Identity Based Encryption From the Weil Pairing
Dan Boneh and Matthew Franklin
Abstract: We propose a fully functional identity-based encryption scheme (IBE).
The scheme has chosen ciphertext security in the random oracle model
assuming an elliptic curve variant of the computational Diffie-Hellman
problem. Our system is based on bilinear maps between groups. The
Weil pairing on elliptic curves is an example of such a map. We give
precise definitions for secure identity based encryption schemes and
give several applications for such systems.
