Abstract

Abstract

Convertible authenticated encryption schemes are studied in this paper. The problems in Wu-Hsus scheme (2002) and Huang-Changs 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.
