An Authenticated Key Agreement Protocol Based on ECDH

For the defects of Diffie-Hellman key exchange and ECDH protocol,an authenticated key agreement protocol is proposed. This proposed protocol is of such security properties as key uncontrollability,key confirmation,perfect forward security,and resistance to known key attacks. Furthermore,this protocol as compared with traditional ones,is simple in management,low in overhead,and high in security,and could achieve secure key agreement and verification between the communication parties with lower computing cost and higher efficiency. Analysis indicates that this protocol is fairly applicable to the end-to-end key management of large-scale networks.
