Identity-Based Cryptosystem Secure E-mail System

摘要：

To solve the key distribution problems in the IBC scheme, this paper proposes a new key distribution protocol based on HIBE key distribution protocol and part of keys manage, which improves the IBC scheme. A new secure E-mail scheme based on Identity-Based Cryptosystems is designed with the combination of GDH group signatures and key manage protocols. It ensures not only the confidentiality, integrity and authenticity, but also the non-repudiation and tracing of the e-mail owing to the improved PKG. The new scheme is compatible with the existing mail protocols and has some practicability as well as application prospects.
