摘要: 自证明签名对验证者来说一次仅验证了两个签名,而在PMI系统中,验证者除了要认证用户身份,其中包括两个验证:一个是验证用户的签名,另一个是验证CA颁发的公钥证书,还需要验证AA颁发的属性证书。针对此问题,该文对自证明签名做了一定的扩展,提出了扩展自证明签名ESCS方案,ESCS由验证两个签名扩展到可同时验证3个签名,此后又对ESCS方案做了进一步的扩展,扩展后的ESCS方案可以同时验证多个签名。

关键词: 扩展自证明签名, DSA, PMI, PKI

Abstract: A verifier verifies only both signer’s signature using self-certified signatures. In PMI system, verifier sides need verify AC issued by AA besides PKC issued by CA which includes two verificationsm, namely user sign and PKC. To the above problem, this paper proposes a new digital signature scheme called multi-certification signature which extents self-certified signatures and verifies two extented to three certifications once. Then, it extents more multi-certification signature which can verfy multi-signatures once.

Key words: Extend self-certification signature, DSA, PMI, PKI
