Research on ring signature based on multilinear pairing
基于多线性映射的环签名研究

An ID-based ring signature scheme was constructed using multilinear pairing on the base of the idea that the generations of the private keys of users were completed by more than one key generation centre. None of the key generation centers could forge a valid ring signature all by itself. All the centers have to collaborate to finish a forgery. The extension of the scheme to support the general access structure was also considered.
