It prevents man-inthe-middle attack with only two more packets required to agree on the secret session key, but it has some weaknesses. In this paper, a new enhanced simple authenticated key agreement algorithm is proposed to overcome these weaknesses on the basis of analyzing the weaknesses of the related protocols. The new enhanced simple authenticated key agreement algorithm can get over replay attack and password guessing attack, provide perfect forward secrecy, and hold the merits of the simple authenticated key agreement algorithm.展开更多

文摘Simple authenticated key agrcement algorithm is one of the Diffie-Hellman key agreement variations. It prevents man-inthe-middle attack with only two more packets required to agree on the secret session key, but it has some weaknesses. In this paper, a new enhanced simple authenticated key agreement algorithm is proposed to overcome these weaknesses on the basis of analyzing the weaknesses of the related protocols. The new enhanced simple authenticated key agreement algorithm can get over replay attack and password guessing attack, provide perfect forward secrecy, and hold the merits of the simple authenticated key agreement algorithm.
