Abstract: Designated verifier proxy signatures allow a signer to delegate signing ability to a proxy signer,who signs messages to a specific designated verifier.Based on Mehta and Harn’s one-time proxy signature,we propose an efficient designated-verifier one-time proxy signature.The scheme satisfies the security requirement,in addition,the computational load is split between online and offline phases.

Key words: signature, one-time proxy signature, trapdoor hash function, designated verifier signature

摘要: 指定接收者的代理签名是将签名的能力委托给代理签名者,其对预先设定的用户进行签名。结合Mehta和Harn的一次代理签名方案和陷门hash函数,首次提出了指定接收人的一次代理签名方案,该方案不仅满足代理签名所需的安全要求,如不可伪造性、可验证性、一次性等,而且,与其它方案相比较,由于方案的运算量分成offline和online两个阶段,从而其效率大大提高。
