key authentication attack

  • 1Key authentication — is a problem that arises when using public key cryptography. It is the process of assuring that the public key of person A held by person B does in fact belong to person A .In traditional symmetric key cryptography, this problem wasn t an issue… …

  • 3Key-agreement protocol — In cryptography, a key agreement protocol is a protocol whereby two or more parties can agree on a key in such a way that both influence the outcome. If properly done, this precludes undesired third parties from forcing a key choice on the… …
