Abstract: Cold boot attack and a large number of side channel attacks may obtain some secret information by observing the implementation features of cryptographic systems. Therefore, the security of the schemes which are based on black box model is likely broken. Leakage resilient cryptography has become a hot topic. Thus, the research on leakage resilient cryptography has not only important theoretical significance but also the corresponding application value. This paper reviews the latest research advances about leakage resilient encryption and gives the systematic analysis. Several leakage-resilient security models in the literature are summarized, and the achievements are introduced and analyzed in detail. Several classical leakage-resilient encryption schemes are introduced and their leakage-resilient principles are analyzed. Several directions for further research are pointed out.

Key words: leakage-resilient, side channel attack, public-key encryption, identity-based encryption, Hash proof system
