摘要: 自证明签名对验证者来说一次仅验证2个签名,而在交叉认证中验证证书链上的证书不止2个,因此,自证明签名在实际的应用中不能满足需求. 针对此问题提出了多证明签名方案,它是在自证明签名的基础上做了一定的扩展,由验证2个签名扩展到可同时验证3个签名;此后又在多证明签名方案的基础上做了进一步的扩展,扩展后的多证明签名方案可同时验证n个签名.

Abstract: A verifier verifies only both signer's signature using self-certified signatures, but it verifies over two certifications to certification chain in cross-certification, it can't be satisfied with demand in actual application. To the above problem, a new digital signature scheme called multi-certification signature was proposed. The method extents self-certified signatures and verifies three certifications once and extents more multi-certification signature which can verifies multi-signatures once.

Key words: multi-certification signature, digital signature algorithm, public key infrastructure, cross-certification
