1. Frequently Asked Questions about Security Keys. What is a security key? A security key is a small physical device that looks like a USB thumb drive, and works in addition to your password on sites that support it. You can carry it on a keychain like a regular key. Here’s a photo: Why should I have one?
2. The security key is the technical term which is generally used with routers, switches, and modems, where for each network SSID there is a unique and different type of security key named as WPA key or WPA2 key or passphrase depending upon the maker of the network device.
3. Generate keys by encrypting (with a private key) a known value + nonce. This can be verified by decrypting using the corresponding public key and verifying the known value. The program now has enough information to verify the key without being able to generate keys.

In the interest of data security, some people are turning to third-party USB devices that act as security keys for their PCs. Without one plugged in, your computer won't unlock. It's as simple as that. There are two ways you can go about getting one of these security keys to add an extra layer of protection: you can buy one, or you can create your own. Let's take a look at both methods, as well as how to actually make your own USB security key using an old thumb drive.

Jan 14, 2018  for one game I have tried over 15 different “working” generators, just one game. All of them led exactly to a “survey” or “verification” that kept trying to go after a credit card. I even went out of my way to buy a visa gift card but ironically t. Nov 05, 2019  Google Authenticator is not a stand-alone software; it is one component of 2FA system and it is associated with the other party by sharing the same key ( symmetric key ). As such, I asks the question, “How do two parties share the same key?” rathe. Basically, the key fob is synchronized with a server and they're both seeded to generate the same sequence of pseudo-random numbers. The server knows it's you if you input the right number at the right time.

One company, Yubico, created the YubiKey, a USB security stick that is compatible with Windows Hello and a bunch of other services that should be kept secure, such as LastPass, KeePass, Google, Dropbox, and Evernote.

Once you have it in your possession, all you have to do is plug it into your PC, register it, and you're ready to go. There are a few different YubiKey options. You have your standard YubiKey that connects via USB, a Nano YubiKey that is much smaller, and a YubiKey NEO that can connect via NFC as well as USB.

For more information on the YubiKey, including detailed instructions on how to get it all setup, be sure to check out our Executive Editor Daniel Rubino's in-depth guide.

How to create your own USB security key

In an article about clever uses for extra USB thumb drives, we mentioned creating your own security key for your PC. Before starting on this endeavor, however, remember that creating a USB security key for your PC comes with some downsides. If you lose the USB key, you'll have a tough time getting into your PC, especially if you disable the ability to enter a password as a backup entry. You're also going to lose the ability to use one of the USB ports on your PC while the lock is active.

There are more than a few options when it comes to the software used for this process, but USB Raptor, Rohos Logon Key, and Predator are a few favorites, although the latter two are paid services. Rohos Logon Key costs $34, while Predator costs $10.

Since USB Raptor is free, we will show you how to get it set up using Windows 10 and an old thumb drive. It really doesn't matter how much space is on the thumb drive, because all that's created is a 1KB .k3y file.

1. Navigate to the USB Raptor SourceForge page.
2. Click the Download button.

3. Click Save.

4. Click Open folder.

5. Right-click the USB Raptor compressed folder.

6. Click Extract All.

7. Click Extract.

8. Double-click the USB Raptor folder.

9. Double-click the USB Raptor application.

10. Click the checkbox next to I have read the disclaimer.

11. Click I agree.

    • USB Raptor will open. At this point, you can plug your USB thumb drive into your PC. Once it's plugged in, you'll be able to continue with the following steps.

12. Type a password. Be sure it's spelled right, and don't forget it!

13. Click the dropdown arrow below Select USB drive.

14. Click a drive. If you only have your USB drive plugged into a USB port, there should only be one option available.

15. Click Create k3y file.

16. Click the checkbox next to Enable USB Raptor when you're ready to start using USB Raptor. A small window will pop up in the bottom-right corner of your screen letting you know that it is enabled.

17. Click Minimize to tray.

As soon as you eject the USB drive or simply pull it out of the port, USB Raptor will kick in. A purple screen shows up with the USB Raptor logo. Only when you plug the USB key back in does it unlock, pretty much instantaneously.

To disable USB Raptor, simply open the app and uncheck the box next to Enable USB Raptor.

This covers the simple configuration that USB Raptor recommends, but there are quite a few advanced settings you can tweak by clicking the checkbox next to Advanced configurations near the top-right corner of the window.

Here you can choose whether or not you'd like to use a password as a backup in the event you lose your USB drive, whether there's a delay on the lock when the USB drive is removed, whether or not the .k3y file is matched to the USB drive's serial number (to prevent copying of the file), and more.

Of course, USB Raptor works perfectly well without messing with the advanced settings, so you don't have to tweak anything you don't want to.

Eyes-on with Minecraft with RTX ray-tracing: They should have sent a poet

/universal-key-generator-2017-mac.html. Minecraft Bedrock Edition beta build is now testing out RTX ray-tracing. Even with modest RTX hardware, it is truly stunning.

^[1]A security token is a peripheral device used to gain access to an electronically restricted resource. The token is used in addition to or in place of a password. It acts like an electronic key to access something. Examples include a wireless keycard opening a locked door, or in the case of a customer trying to access their bank account online, the use of a bank-provided token can prove that the customer is who they claim to be.

Some tokens may store cryptographic keys that may be used to generate a digital signature, or biometric data, such as fingerprint details. Some may also store passwords.^[2] Some designs incorporate tamper resistant packaging, while others may include small keypads to allow entry of a PIN or a simple button to start a generating routine with some display capability to show a generated key number. Connected tokens utilize a variety of interfaces including USB, near-field communication (NFC), radio-frequency identification (RFID), or Bluetooth. Some tokens have an audio capability designed for vision-impaired people.

Password types[edit]

All tokens contain some secret information that is used to prove identity. There are four different ways in which this information can be used:

Static password token

The device contains a password which is physically hidden (not visible to the possessor), but which is transmitted for each authentication. This type is vulnerable to replay attacks.

Synchronous dynamic password token

A timer is used to rotate through various combinations produced by a cryptographic algorithm. The token and the authentication server must have synchronized clocks.

Asynchronous password token

A one-time password is generated without the use of a clock, either from a one-time pad or cryptographic algorithm.

Challenge response token

Using public key cryptography, it is possible to prove possession of a private key without revealing that key. The authentication server encrypts a challenge (typically a random number, or at least data with some random parts) with a public key; the device proves it possesses a copy of the matching private key by providing the decrypted challenge.

One-time passwords[edit]

Time-synchronized one-time passwords change constantly at a set time interval; e.g., once per minute. To do this some sort of synchronization must exist between the client's token and the authentication server. For disconnected tokens this time-synchronization is done before the token is distributed to the client. Other token types do the synchronization when the token is inserted into an input device. The main problem with time-synchronized tokens is that they can, over time, become unsynchronized.^{[citation needed]} However, some such systems, such as RSA's SecurID, allow the user to resynchronize the server with the token, sometimes by entering several consecutive passcodes. Most also cannot have replaceable batteries and only last up to 5 years before having to be replaced – so there is additional cost.^{[citation needed]}

Another type of one-time password uses a complex mathematical algorithm, such as a hash chain, to generate a series of one-time passwords from a secret shared key. Each password is unguessable, even when previous passwords are known. The open source OAuth algorithm is standardized; other algorithms are covered by US patents. Each password is observably unpredictable and independent of previous ones, wherefore an adversary would be unable to guess what the next password may be, even with knowledge of all previous passwords.

Physical types[edit]

Tokens can contain chips with functions varying from very simple to very complex, including multiple authentication methods.

The simplest security tokens do not need any connection to a computer. The tokens have a physical display; the authenticating user simply enters the displayed number to log in. Other tokens connect to the computer using wireless techniques, such as Bluetooth. These tokens transfer a key sequence to the local client or to a nearby access point.

Alternatively, another form of token that has been widely available for many years is a mobile device which communicates using an out-of-band channel (like voice, SMS, or USSD).

Still other tokens plug into the computer, and may require a PIN. Depending on the type of the token, the computerOS will then either read the key from the token and perform a cryptographic operation on it, or ask the token's firmware to perform this operation

A related application is the hardware dongle required by some computer programs to prove ownership of the software. The dongle is placed in an input device and the software accesses the I/O device in question to authorize the use of the software in question.

Commercial solutions are provided by a variety of vendors, each with their own proprietary (and often patented) implementation of variously used security features. Token designs meeting certain security standards are certified in the United States as compliant with FIPS 140, a federal security standard. Tokens without any kind of certification are sometimes viewed as suspect, as they often do not meet accepted government or industry security standards, have not been put through rigorous testing, and likely cannot provide the same level of cryptographic security as token solutions which have had their designs independently audited by third-party agencies.^{[citation needed]}

Disconnected tokens[edit]

Disconnected tokens have neither a physical nor logical connection to the client computer. They typically do not require a special input device, and instead use a built-in screen to display the generated authentication data, which the user enters manually themselves via a keyboard or keypad. Disconnected tokens are the most common type of security token used (usually in combination with a password) in two-factor authentication for online identification.^[3]

Connected tokens[edit]

Connected tokens are tokens that must be physically connected to the computer with which the user is authenticating. Tokens in this category automatically transmit the authentication information to the client computer once a physical connection is made, eliminating the need for the user to manually enter the authentication information. However, in order to use a connected token, the appropriate input device must be installed. The most common types of physical tokens are smart cards and USB tokens, which require a smart card reader and a USB port respectively. Increasingly, Universal 2nd Factor (U2F) tokens, supported by the open specification group FIDO Alliance have become popular for consumers with mainstream browser support beginning in 2015 and supported by popular websites and social media sites.

Older PC card tokens are made to work primarily with laptops. Type II PC Cards are preferred as a token as they are half as thick as Type III.

The audio jack port is a relatively practical method to establish connection between mobile devices, such as iPhone, iPad and Android, and other accessories. The most well known device is called Square, a credit card reader for iPhone and Android.

Some use a special purpose interface (e.g. the crypto ignition key deployed by the United States National Security Agency). Tokens can also be used as a photo ID card. Cell phones and PDAs can also serve as security tokens with proper programming.

Smart cards[edit]

How Do Security Key Generators Work On Iphone

Many connected tokens use smart card technology. Smart cards can be very cheap (around ten cents)^{[citation needed]} and contain proven security mechanisms (as used by financial institutions, like cash cards). However, computational performance of smart cards is often rather limited because of extreme low power consumption and ultra-thin form-factor requirements.

Quick heal total security 2016 serial key generator. Smart-card-based USB tokens which contain a smart card chip inside provide the functionality of both USB tokens and smart cards. They enable a broad range of security solutions and provide the abilities and security of a traditional smart card without requiring a unique input device. From the computer operating system's point of view such a token is a USB-connected smart card reader with one non-removable smart card present.^[4]

Contactless tokens[edit]

Unlike connected tokens, contactless tokens form a logical connection to the client computer but do not require a physical connection. The absence of the need for physical contact makes them more convenient than both connected and disconnected tokens. As a result, contactless tokens are a popular choice for keyless entry systems and electronic payment solutions such as MobilSpeedpass, which uses RFID to transmit authentication info from a keychain token. However, there have been various security concerns raised about RFID tokens after researchers at Johns Hopkins University and RSA Laboratories discovered that RFID tags could be easily cracked and cloned.^[5]

Another downside is that contactless tokens have relatively short battery lives; usually only 5–6 years, which is low compared to USB tokens which may last more than 10 years.^{[citation needed]} Some tokens however do allow the batteries to be changed, thus reducing costs.

Bluetooth tokens[edit]

The Bluetooth Low Energy protocols serve for long lasting battery lifecycle of wireless transmission.

• The transmission of inherent Bluetooth identity data is the lowest quality for supporting authentication.
• A bidirectional connection for transactional data interchange serves for the most sophisticated authentication procedures.

However the automatic transmission power control antagonizes to attempts for radial distance estimates. The escape is available apart from the standardised Bluetooth power control algorithm to provide a calibration on minimally required transmission power.^[6]

Bluetooth tokens are often combined with a USB token, thus working in both a connected and a disconnected state. Bluetooth authentication works when closer than 32 feet (10 meters). When the Bluetooth link is not properly operable, the token may be inserted into a USBinput device to function.

Another combination is with smart card to store locally larger amounts of identity data and process information as well.^[7] Another is a contactless BLE token that combines secure storage and tokenized release of fingerprint credentials.^[8]

In the USB mode of operation sign-off requires care for the token while mechanically coupled to the USB plug. The advantage with the Bluetooth mode of operation is the option of combining sign-off with distance metrics. Respective products are in preparation, following the concepts of electronic leash.

NFC tokens[edit]

Near-field communication (NFC) tokens combined with a Bluetooth token may operate in several modes, thus working in both a connected and a disconnected state. NFC authentication works when closer than 1 foot (0.3 meters). The NFC protocol bridges short distances to the reader while the Bluetooth connection serves for data provision with the token to enable authentication. Also when the Bluetooth link is not connected, the token may serve the locally stored authentication information in coarse positioning to the NFC reader and relieves from exact positioning to a connector.^{[citation needed]}

Single sign-on software tokens[edit]

How Do Home Generators Work

Some types of single sign-on (SSO) solutions, like enterprise single sign-on, use the token to store software that allows for seamless authentication and password filling. As the passwords are stored on the token, users need not remember their passwords and therefore can select more secure passwords, or have more secure passwords assigned. Usually most tokens store a cryptographic hash of the password so that if the token is compromised, the password is still protected.^{[citation needed]}

Programmable tokens[edit]

Programmable tokens are marketed as 'drop-in' replacement of mobile applications such as Google Authenticator (miniOTP^[9]). They can be used as mobile app replacement, as well as in parallel as a backup.

Vulnerabilities[edit]

Any means and measures for securing data may be overcome. This applies as well for security tokens. The major threat is by incautious operation. Users shall be aware of permanent options of threat.

Loss and theft[edit]

The simplest vulnerability with any password container is theft or loss of the device. The chances of this happening, or happening unawares, can be reduced with physical security measures such as locks, electronic leash, or body sensor and alarm. Stolen tokens can be made useless by using two factor authentication. Commonly, in order to authenticate, a personal identification number (PIN) must be entered along with the information provided by the token the same time as the output of the token.

Attacking[edit]

Any system which allows users to authenticate via an untrusted network (such as the Internet) is vulnerable to man-in-the-middle attacks. In this type of attack, a fraudster acts as the 'go-between' of the user and the legitimate system, soliciting the token output from the legitimate user and then supplying it to the authentication system themselves. Since the token value is mathematically correct, the authentication succeeds and the fraudster is granted access. Citibank made headline news in 2006 when its hardware-token-equipped business users became the victims of a large Ukrainian-based man-in-the-middle phishing attack^[10][11].

Breach of codes[edit]

In 2012, the Prosecco research team at INRIA Paris-Rocquencourt developed an efficient method of extracting the secret key from several PKCS #11 cryptographic devices, including the SecurID 800.^[12][13] These findings were documented in INRIA Technical Report RR-7944, ID hal-00691958,^[14] and published at CRYPTO 2012.^[15]

Digital signature[edit]

Trusted as a regular hand-written signature, the digital signature must be made with a private key known only to the person authorized to make the signature. Tokens that allow secure on-board generation and storage of private keys enable secure digital signatures, and can also be used for user authentication, as the private key also serves as a proof of the user’s identity.

For tokens to identify the user, all tokens must have some kind of number that is unique. Not all approaches fully qualify as digital signatures according to some national laws.^{[citation needed]} Tokens with no on-board keyboard or another user interface cannot be used in some signing scenarios, such as confirming a bank transaction based on the bank account number that the funds are to be transferred to.
