IKE authentication using certificateless signature

Aiming at the problems of implementing the conventional IKE authentications such as pre-shared key and certificate-based Public Key Infrastructure (PKI), this paper proposes a new certificateless IKE authentication scheme. This scheme uses bilinear pairing to structure the framework of certificateless IKE authentication, solves the end to end IPSec security by removing the requirement of both nodes either to be manually configured with the common shared key or to exchange the certificates and the necessity to be enrolled to certain Certificate Authority (CA). Furthermore, this paper provides a set of specifications for implementing IKE authentication using certificateless signature that can be used to verify the validity of the scheme in a single trust domain infrastructure.
