Abstract. Certificateless cryptography introduced by Al-Riyami and Paterson eliminates the key escrow problem inherent in identity based cryptosystems. Even though building practic...

Abstract: Recently, Au et al. [Au et al. 2007] pointed out a seemingly neglected security concern for certificateless public key encryption (CL-PKE) scheme, where a malicious key g...
Abstract-Secure cooperation incentive schemes usually use public key cryptography, which incur too heavy overhead to be used efficiently in limited-resource nodes. In this paper, w...
In this work, we study a new multivariate quadratic (MQ) assumption that can be used to construct public-key encryption schemes. In particular, we research in the following two di...
