矢量空间RSA数字签名方案

A vector space RSA digital signature scheme

基于矢量空间秘密共享方案和RSA签名方案提出了一种新的签名方案,即矢量空间RSA签名方案,该方案包括文献[1]中方案作为其特殊情况。在该方案中,N个参与者共享RSA签名方案的秘密密钥,能保证矢量空间访问结构G中参与者的授权子集产生有效的RSA群签名,而参与者的非授权子集不能产生有效的RSA群签名。

A new digital signature scheme, i.e. vector space RSA digital signature scheme, which includes the scheme in [1] as a particular case, is proposed based on vector space secret sharing scheme and RSA digital signature scheme. In this scheme, N participants share the secret in RSA signature scheme. This scheme can assure that the group signature can be easily produced by the cooperation of the participants in an authorized subset in vector space access structure G and it is impossible for them to generate a group signature by the cooperation of the participants in an unauthorized subset.
