4Known-Key Security Sample Clauses

4Known-Key Security. The known-key security signifies towards guessing the private keys of the related participants, on condition that the session key is compromised. For instance, if the session key H(TaTSr(x))=H(TSrTa(x)) gets exposed, it will not let the attacker guess any Sy, Sx or Ui secrets i.e., a, PWU, Sr, or Kxy, Ky. Although PWU is a low entropy password, it would be a hard problem to guess the password from public messages. The rest of the secret parameters a, Sr, Kxy, Ky are very hard to guess for being high entropy integers.
