摘要

提出两个新的基于分级身份的签名方案.在随机应答模型下

新方案有如下结果:两个方案中的签名算法效率都很高;这两个方案是可证明安全的

在给定身份和选择明文攻击下是不可伪造的; 第二个方案的签名长度是常数

与分级深度无关; 两个方案都能达到安全归约紧致的要求.

Abstract

Two new hierarchical identity-based signature (HIBS) schemes are proposed.In random oracle model

the two schemes have the following results:The signature generation algorithms are efficient;They are provably secure and have good exact security against existential forgery for selective-ID attack;Signature size in the latter HIBS scheme is constant and independent to hierarchy depth;Both HIBS schemes have tight security reduction.
