Shared Verification Signature Scheme Based on Hyper-elliptic Curves Cryptosystem
LI Delong · Jisuanji gongcheng · 2007
Analyses are made on the security threats and system flaws of present shared verification signature schemes,and an improved shared verification signature scheme based on hyper-elliptic curves cryptosystem that can gain a wide application in computer and wireless communication network is presented.The probabilistic encryption algorithm in the scheme avoids the relevance between different signatures generated by the same signer,prevents coalition and generalized signature forgery.Further analyses also justify its brevity,security,high efficiency,and thus considerable improvement on system overheads regarding software and hardware application.
