In this paper we introduce the notion of certificateless proxy re-encryption and also give precise definitions for secure certificateless proxy re-encryption schemes. We present a concrete scheme based on bilinear pairing, which enjoys the advantages of certificateless public key cryptography while providing the functionalities of proxy re-encryption. Moreover, the proposed scheme is unidirectional and compatible with current certificateless encryption deployments. Finally, we show that our… CONTINUE READING
