A PUBLICLY VERIFIABLE AUTHENTICATED ENCRYPTION SCHEME WITHOUT USING ONE-WAY HASH FUNCTION

摘要：

Most of currently publicly verifiable authenticated encryption schemes based on the conventional one-way Hash function have a security hole that these schemes are vulnerable to the universal forgery attack.The security weakness of Ma-Chens publicly verifiable authenticated encryption scheme has been shown in this paper.In order to overcome this problem, without using any conventional one-way hash function we proposed an improved scheme based on only the Discrete Logarithm Problem(DLP).Further, the proposed scheme is more efficient than Ma-Chens in terms of the computation cost.
