多证明签名方案及在交叉认证中的应用

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.

Multi-Certification Signature Scheme and Its Application to Cross-Certification

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.
