Describe a method that allows a client to authenticate multiple times to a server with the following requirements:

a. The client and server use constant space for authentication.

b. Every time the client authenticates to the server, a different random value for authentication is used (for example, if you have n authentication rounds, the client and the server have to use n different random values—this means that sharing a key initially and using it for every round of authentication is not a valid solution).

Can you find any vulnerabilities for this protocol?
