New Leakage Resilient CCA-Secure Public Key Encryption

Building cryptographic schemes secure even if the secrets are partially leaked is a trend in cryptography, motivating partially from side channel attacks. In this paper, the authors are interested in Public Key Encryption (PKE) schemes with leakage resilience. This paper shows a generic method of constructing CCA- secure Public Key Encryption schemes with leakage resilience on the secret key. It is based on a new kind of universal hash proof system which accepts an auxiliary parameter. Specifically, two schemes are presented, basing on the DCR assumption and DLIN assumption respectively.
