Abstract: | 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. |
