AN ID-BASED DESIGNATED-VERIFIER PROXY MULTI-SIGNATURE SCHEME WITHOUT TRUSTED PKG
摘要
Abstract
An ID-based designated-veriiier proxy multi-signature scheme without trusted PKG is proposed by using the bilinear pairings in this paper. The scheme supposes that Private Key Generator (PKG) is not a trusted dealer, and user' s private key is generated by the PKG and user together. Compared with the existing ID-based designated-verifier proxy signature, the new scheme can prevent user' s secret key from leaking and solve the problems that the existing ID-based proxy signature need to trust PKG unconditionally. Analysis shows that the scheme is secure and has the practicability to certain extent.关键词
