Abstract

After Shamir proposed his scheme, other authors proposed many Identity-Based Encryptions. The models were assumed in the random oracle model with a variant of the computational Diffie-Hellman problem. In our paper we propose a new variant of Identity-Based Encryption (IBE), using elliptic curves schemes and prove his security completeness. Also, we are doing a complete description of the necessary system used in the present scheme in order to secure a communication. The performance of our system is comparable to the performance of ElGamal encryption in Fp * and the security of the system is based on the elliptic curve calculus intractability. Keywords: identity-based encryption, Diffie-Hellman problem, elliptic curves cryptography, Escrow ElGamal. 1 Introduction In the
