Establishment of ECC-Based Initial Secrecy Usable for IKE Implementation
Internet Key Exchange (IKE) protocol is the most common usable mechanism to exchange keying materials and negotiate security associations between two distant entities. Similar to the several enhancements of the IKE protocols, the paper proposes a new flexible approach for complexity reduction and security improvement of the IKE implementation. In this paper, an initial secret key negotiation based on Elliptic Curve Cryptography (ECC) for phase 1 of IKE has been proposed, which instead of RSA, uses ECC based public key certificate for authentication of the entities. The proposed scheme thus requires comparatively less processing time and provides equivalent secrecy with less key size.
