摘要: 該文對(duì)可轉(zhuǎn)變認(rèn)證加密進(jìn)行了研究，指出了Wu-Hsu(2002)方案和Huang-Chang(2003)方案中存在的問(wèn)題，分別給出了這兩個(gè)方案的改進(jìn)方案，很好地解決了認(rèn)證加密方案的公開(kāi)驗(yàn)證問(wèn)題。

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. -
