摘要
该文对可转变认证加密进行了研究,指出了Wu-Hsu(2002)方案和Huang-Chang(2003)方案中存在的问题, 分别给出了这两个方案的改进方案,很好地解决了认证加密方案的公开验证问题。
Convertible authenticated encryption schemes are studied in this paper The problems in Wu-Hsu's scheme (2002) and Huang-Chang's scheme (2003) are pointed out. Furthermore the improvements of the two schemes are given; for that, the public verification of authenticated encryption schemes is solved as well.
