Abstract: Identity-based encryption(IBE) is a form of public key encryption which uses the identity as a public key. The identity-based encryption schema are introduced and compared with PKI. This paper analyses the interaction model of a secure E-mail system based on IBE and its security design and gives implementation of the system.
