摘　　要：切尼提出了一种带有信号恢复的签名方案,但是米切尔和尤尼称这种方案仅仅是一种鉴别编码方案而并非签名方案。在理解米切尔和尤尼的观点的基础上,提出了一种带有信号恢复特征的新签名方案;在詹科比森提出的指定检验者的签名方案的基础上,提出了一种带有防发送方抵赖的指定检验者的签名方案,并为该方案给出了协议。Recently, Chen proposed a signature with message recovery. But Mitchell and Yeun observed that Chen＇s scheme is only an authenticated encryption scheme and not a signature scheme as claimed. A new signature scheme with message recovery feature is proposed in the sense ofMitchell and Yeun. The designated verifier signature is introduced by Jakobsson et al. A designated verifier signature scheme with non-repudiation of origin is put forward. Protocols for a convertible designated verifier signature scheme with non-repudia-tion of origin are also given. Both of these schemes are based on signature scheme with message recovery which is brought forward.
