Identity-based Cryptography

Description

Identity-based cryptography (IBC) is the enabling technology of next generation public key infrastructure. By allowing any user identity to be used as a public key, IBC is widely believed to be a promising technology to make security applications much more user friendly than ever before. However, before IBC can be introduced to a wide range of applications, some crucial research problems that are still inherent in IBC need to be solved. Problems include the key escrow problem, the implementation efficiency of various identity-based cryptographic primitives, the system architecture of IBC, and key renewal, revocation and registration issues. In this project, the researchers plan to find solutions to these problems, and the ultimate objective is to reduce the gap between the security levels of identity-based cryptographic techniques and the user friendliness of these techniques.
