an identifier. The verifier can ask for any of the passwords, and the prover must have that correct password for that identifier. Assuming that the passwords are chosen independently, an adversary who intercepts one challenge–response message pair has no clues to help with a different challenge ...
The simplest example of a challenge–response protocol ispasswordauthentication, where the challenge is asking for the password and the valid response is the correct password. Clearly an adversary who can eavesdrop on a password authentication can then authenticate itself in the same way. One solution...
The invention relates to a challenge-response device (1) comprising an input (5) for receiving a challenge signal from a terminal and an output (6) for emitting a response signal. The challenge-response device (1) also comprises a feedback shift register (2), a memory (3) for saving a...

Secure Shell (SSH) protocolincludes a challenge-response mechanism that uses separate public key infrastructure (PKI) to authenticate communication sessions between servers. Each server authenticates itself by sending the other a value signed with the other's public key. ...
Challenge-response authentication is a group or family of protocols characterized by one entity sending a challenge to another entity. The second entity must respond with the appropriate answer to be authenticated. Advertisements A simple example of this is password authentication. The challenge is from...
A challenge-response user-authentication procedure masks an authentication center's expected response (XRES) utilizing a masking function () and by transmitting a random challenge and a masked expected response (XRES′) instead of the XRES to an intermediate party where the actual user authentication...

If the server returns a 401 as expected, the client will respond to the challenge and eventually upload the entire POST-body. If, however, the server does not return a 401 response, the client will simply submit the single zero-byte post, which likely will lead to an error message o...
