摘要 对已有多重签名方案进行了安全性分析,提出了可证安全的广播多重盲签名方案。给出了改进的广播多重盲签名算法和验证算法,并证明了改进方案满足盲性和不可伪造性。比较和分析了改进方案的复杂度和安全性,改进方案的运算量减少了37.2n+447.8TML。改进方案所需运算量少,安全性高且易于实现。 Multisignature algorithm by reference is analyzed. Provably secure broadcast blin d multisignature scheme is pre-sented. Specific signature and verification algorithms of Improved broadcast blind multisignature scheme are given. And the Im -proved scheme meets the properties of both blindness and non-forgery. The complexity and security of improved scheme are com-pared and analyzed. Improved scheme reduces computation costs 37.2n+447.8TML. Improved scheme has the advantages of low com-putation complexity, high security and easy to achieve.
