在层次结构下实现基于身份的签密

The Identity-Based Signcryption Schemes in Hierarchical Cryptosystem

对层次结构下基于身份的签密进行了详细的研究。先基于The Malone-Lee的签密方案,提出一种在层次结构下实现基于身份的签密方案。然后,为提高效率,根据不同的情况提出了几个不同的改进方案,为层次结构下基于身份签密的实际应用提供了较好的基础。

We research how to use the identity-based signcryption in hierarchical cryptosystem. Firstly, we proposed a scheme based on the Malone-Lee scheme. Then we proposed some improved schemes for different conditions in order to improve efficiency. Based on these schemes, we proved a better foundation for the application of the identity-based signcryption.
