Efficient ID-based signature scheme without trusted party
高效的基于ID的无可信中心签名方案

This paper proposed an efficient ID-based signature scheme without trusted party against the problem of key escrow of ID-based signature system. The new scheme could solve the key escrow problem through binding two partially public keys with a same identity and has been proved secure against existential forgery on adaptively chosen message and ID attack under random oracle model. The efficiency of the scheme is higher than the existing schemes.
