Kilian, Joe (ed.), Advances in cryptology - CRYPTO 2001. 21st annual international cryptology conference, Santa Barbara, CA, USA, August 19-23, 2001. Proceedings. Berlin: Springer. Lect. Notes Comput. Sci. 2139, 213-229 (2001).
Summary: We propose a fully functional identity-based encryption scheme. 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 the Weil pairing. We give precise definitions for secure identity based encryption schemes and give several applications for such systems.
