A Certificateless Multiple-key Agreement Protocol Based on Bilinear Pairings
Certificateless cryptosystems were proposed by Al-Riyami and Paterson in 2003 [1] to solve problems of public key cryptosystems based on PKI and based on identity. Up to now, various types of certificateless cryptographic primitives as encryption functions, signature schemes, key agreement protocols and etc, have been designed. But to the best of our knowledge, multiple-key agreement protocols have not been proposed based on certificateless cryptosystem yet. So in this paper we propose a certificateless authenticated multiple-key agreement protocol with bilinear pairings.
