CHALLENGE-RESPONSE ENTITY AUTHENTICATION TECHNIQUES. Authors: HOREA OROS, FLORIAN MIRCEA BOIAN. |
||||||
Abstract: Entity authentication is a process by which one party obtains evidence regarding the identity of a second party involved in a protocol, and that the second party effectively participated to the process, being active when the evidence is obtained or immediately prior to the time the evidence is acquired. This paper presents general techniques used in entity authentication protocols, techniques based on challenge-response mechanism. These techniques use time-variant parameters in the form of random numbers, sequence numbers or times-tamps. We investigate challenge-response techniques based on symmetric and asymmetric cryptography. Key words and phrases. authentication, protocol, challenge-response, nonce. |
