| Popis: | 83 In this thesis, two new authentication protocols are proposed. In the first part, we present a four-message protocol for initial authentication that supports subsequent authentication in two messages without contacting the authentication server or using synchronized clocks. This protocol has the property of using fewer messages to provide better security than Kerberos and better reliability and security than the NS and Permuted protocols. Based on the protocol, a secure authentication system is built, which uses the master-slave scheme. In the second part, we propose a secure authentication protocol which supports both the privacy of messages and the authenticity of communicating parties in wireless networks. The trusted third party (key information center) is not needed once the secure network system is set up. Mutual authentication and key distribution can be achieve with two messages merely between two parties involved. With lower computation overhead, this protocol resolves the problems, appeared in the Okamoto and Tanaka's ID-based scheme, that user identities may be forged and user secret information may be discolsed. It can also protect user communication from replay attacks even if system clocks are not synchronized. |
