Identity Based Encryption is a type of public key cryptography in which users' public key is some unique information about the identity of the user. IBE scheme relies on a trusted third party, called private key generator or PKG, to generate corresponding private keys. An inherent problem of this system is key escrow. It also requires a secure channel between users and the PKG to deliver private keys. This paper describes several proposals that would eliminate those problems. It is also describes how to make identity based encryption more applicable by providing a secure issuing mechanism that would ensure user privacy and authenticity.
