Convertible Authenticated Encryption Scheme
YU Zhao-ping · Jisuanji gongcheng · 2007
All the existed authenticated encryption schemes either have only considered the process of authenticated signature without using Hash functions and redundancy functions or have only discussed the signature’s convertibility.So it proposes a new convertible authenticated encryption scheme without using Hash functions and redundancy functions which are based on ECC.The convert of signature in this scheme can be executed without signer.The scheme’s security is analysed.
