Key agreement protocol based on the conic curve cryptography

Key management is the core problem of network system security, which deals with the correlative problems from key being generated to ultimately destroyed; it includes system initialization, key generation, key encasement, key distribution, key storage, key renovation, key destruction, etc. In which, the critical problem is key storage and key destruction. Key distribution technology is researched in this paper. A new key distribution protocol, based on the public-key cryptography of conic curve, was proposed, in which the security relied on the conic curve discrete logarithm problem. The protocol can provide identity authentication, key validation, perfect forward secrecy, and foil man-in-the-middle attacks.
