In the paper, an algorithm fitted to P2P system was proposed by improving Kerberos which is an algorithm for mutual authentication. To keep the role of Kerberos and minimize load to server, the proposed algorithm imposed the server role of ticket recognition to the opposite peer. Using this method, the number of sewers as ticket recognition server was averted and function of server for authentication was minimized so that server load was mininized. The proposed algorithm enables the server to play the minimum of the role and to perform strong mutual authentication, while imposeing on the peers the role of authentication. To make suitable to P2P system, trial number oriented authentication limit was given, not time-oriented authentication expiration time. In the paper, a new P2P system was designed using this algorithm.
