Abstract:

Aiming at overcoming the shortages of the current proposed K-selection algorithm for evolved packet system (EPS) authentication and key agreement, an automatic K-selection algorithm on the base of authentication numbers was put forward. Based on message exchange traffic, this algorithm adds the bit exchange traffic as measures and introduces the two wastage rate of authentication vectors. Simulation shows that the proposed algorithm effectively reduces bit exchange traffic and message exchange traffic, and gains an unique K value.

Key words: authentication and key agreement, message exchange traffic, bit exchange traffic, authentication vector array
