Homomorphism key agreement based on ECC
Ma Jie · Jisuanji gongcheng yu sheji · 2007
The basic content of key management is reviewed,and the limitation of the existing key agreement protocol is poinfed out.ECC public key cryptosystems and homomorphic encryption scheme in the integer ring is introduced in detail.The homomorphism key agreement based on ECC and homomorphic encryption scheme is presented.Compared with Diffie-Hellman protocol,its operation speed is more quick and compared with key agreement protocol based on password,it has better security.The protocol use the public key of ECC to create the contributory,forward secrecy the session key.Finally,the security of the protocol is proved by BAN logic.
