Improved ID-based Threshold Proxy Re-signature Scheme
摘要
Abstract
Based on ID-based proxy re-signature, an ID-based bidirectional threshold proxy re-signature scheme without random oracles is presented, and its security in the standard model is proved.The analysis result shows that it is robust and secure against existential forgery under the adaptive chosen identity and message attacks.The length of public parameters of the scheme is shorter than that of previously known ID-based bidirectional threshold proxy re-signature scheme in the standard model, and the security of the scheme is tightly reduced to the security of the q-Strong Diffie-Hellman(q-SDH) problem.关键词
