Concurrent Impersonation Attack (Dictionary Entry)

Quotes

Concurrent Impersonation Attack: this attack further extends the active attack in that the adversary can choose to engage, acting as a server, in concurrent executions of the identification scheme with a different instantiation of P (using the same public and private keys), until it decides to make an impersonation attempt; thus, at any given time, the adversary can decide to start a new session with a new instantiation of P, to continue a previous session by sending the next verifier’s message, or to start the impersonation attempt.
