Secure Certificateless Public Key Encryption without Redundancy
Yinxia Sun Futai Zhang
Certificateless public key cryptography was introduced to solve the key escrow problem in identity based cryptography while enjoying the most attractive {\em certificateless} property. In this paper, we present the first {\em secure} certificateless public key encryption (CLPKE) scheme {\em without redundancy}. Our construction provides optimal bandwidth and a quite efficient decryption process among all the existing CLPKE schemes. It is provably secure against adaptive chosen ciphertext attacks in the random oracle model under a slightly stronger assumption.
