What is challenge-response method?

In computer security, challenge-response authentication is a set of protocols used to protect digital assets and services from unauthorized users, programs or activities. While challenge-response authentication can be as simple as a password, it can also be as dynamic as a randomly generated request.

How do you respond to the YubiKey challenge?

HMAC-SHA1 Challenge-Response (recommended)

Select Challenge-response and click Next. Generate a secret key by clicking Generate, and copy it somewhere (this will be needed later for KeePass setup). If desired, check Require touch. Click Finish, and confirm if prompted.

What happens when I touch my YubiKey?

The YubiKey has an integrated touch-contact that triggers the OTP generation. Generated OTPs are sent as keystrokes by the emulated keyboard, thereby allowing the OTPs to be received by any text input field or command prompt.

An adversary who can eavesdrop on a password authentication can then authenticate itself by reusing the intercepted password.

How does YubiKey generate code?

The YubiKey is a device that makes two-factor authentication as simple as possible. Instead of a code being texted to you, or generated by an app on your phone, you press a button on your YubiKey. That's it. Each device has a unique code built on to it, which is used to generate codes that help confirm your identity.

FIDO2 - the YubiKey 5 can hold up to 25 resident keys in its FIDO2 application. OATH (Yubico Authenticator) - the YubiKey 5's OATH application can hold up to 32 OATH-TOTP credentials (AKA authenticator app codes).

What is challenge phrase authentication?

Challenge-response authentication uses a cryptographic protocol that allows to prove that the user knows the password without revealing the password itself. Using this method, the application first obtains a random challenge from the server.

What is Hmac in security?

Hash-based Message Authentication Code (HMAC) is a message authentication code that uses a cryptographic key in conjunction with a hash function. Hash-based message authentication code (HMAC) provides the server and the client each with a private key that is known only to that specific server and that specific client.

What is a challenge and response environment?

In a good Challenge and Response environment, everybody feels free to question assumptions and actions, and positive responses are normal. Here, we are dealing with challenging concepts. By concepts, we mean our mental picture, the understanding and assumptions about a situation.

What is a challenge code?

– The Challenge Code is a code that you choose – not something you have to receive via email, phone call, or text. – With this feature, you will avoid having to receive and enter an access code each time you login. • Setting up your Challenge Code is simple, and will only take a few moments.

What is MD5 challenge response?

In EAP MD5-Challenge, the RADIUS server sends a random challenge to the client. The client forms an MD5 hash of the user's password and the challenge and sends the result back to the server. The server then validates the MD5 hash using the known correct plaintext password from the user database.

How is a challenge response protocol utilized with token device implementation?

How is a challenge/response protocol utilized with token device implementations? This protocol is not used; cryptography is used. The token challenges the user for a username and password. An authentication service generates a challenge, and the smart token generates a response based on the challenge.

What is the difference between FIDO and FIDO2?

FIDO2 stands for Fast Identity Online 2 and is also referred to as “The New Passwordless Standard.” The original FIDO was created by the FIDO Alliance to require better authentication standards for passwords and logins.

How do FIDO2 keys work?

The FIDO protocols use standard public key cryptography techniques to provide stronger authentication. During registration with an online service, the user's client device creates a new key pair. It retains the private key and registers the public key with the online service.

Why is FIDO more secure?

FIDO protocols use standard public key cryptography techniques to secure user authentication. All communications are encrypted and private keys never leave users' devices, which lessens the chances of someone discovering them during transmission.
