Efficient certificateless multi-signature scheme
一种高效的无证书多重签名方案*

In order to meet the high efficiency of the multi-signature,by combining certificateless cryptosystem with the multi-signature scheme,this paper proposed an efficient certificateless multi-signature scheme.The scheme was weaken the power of the trusted third party and proved existing unforgeability under the adaptive chosen message attack. The security of the scheme was based on the fact that computational Diffie-Hellman problem was hard.Compared with existing schemes,the scheme need calculate less bilinear pairing and reduce the system costs.
