Agent System POND 1.0 (1.7.2000)

Class AcceptAndReplyChallengeMessage


public class AcceptAndReplyChallengeMessage
extends ChallengeIdentityMessage

A message to reply to a ChallengeIdentityMessage. Third part in a mutual authentication. The length of the challenge is restricted to 16 bytes. Otherwise it would be possible to submit certain data and let the computer sign it without knowing its content. To avoid this, also some bytes are inserted (which hopefully destroy any normal meaning!).
