Abstract: |
A key distribution procedure is an essential constituent of secured exchange of information between the participants. In this paper, a fast symmetric key distribution technique with additional services is presented. The aim of the proposed technique is to improve the conventional Needham-Schroeder five-message protocol in four aspects. The first aspect is to introduce an additional authentication level in originator’s identity and the second aspects to provide the integrity of the originator’s message. The third aspect is to reduce the time needed to distribute a session-key between a pair of entities, and the fourth aspect is to develop the key freshness for security. |
