Abstract :
Group key agreement based on elliptic curve at ad hoc networks is studied. In order to meet the demand of efficiency and security, an improved key exchange scheme based on elliptic curve is proposed in this paper. In the scheme, elliptic curve cryptosystem and digital signature algorithm in elliptic curve field are combined to make a group key. The key is agreed on within all members who would participate in the conversation. The new improved scheme has not only the features of forward security, backward security and resisting attack, but also certain theoretical and practical values.
