Certificateless Authenticated Group Key Agreement Scheme with Privacy-Preservation for Resource-Limited Mobile Devices
A group key agreement scheme is to establish a secret key shared among some participants for secure group-oriented applications. Many authenticated group key agreement schemes have been proposed, but few of them provide user anonymity for wire-less mobile networks. Considering the user privacy issues and the characteristics of wireless mobile networks, the authors proposed a certificateless authenticated group key agreement scheme with privacy-preservation based on elliptic curve discrete logarithms. Resource-limited mobile devices can efficiently, cooperatively and anonymously establish an authenticated group key with entity authentication using no public key certificates in mobile wireless networks.
