[Resource Topic] 2012/453: New Leakage Resilient CCA-Secure Public Key Encryption

Welcome to the resource topic for 2012/453

Title:
New Leakage Resilient CCA-Secure Public Key Encryption

Authors: Kaoru Kurosawa, Ryo Nojima, Le Trieu Phong

Abstract:

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$_2$ hash proof system which accepts an auxiliary parameter. Specifically, two schemes are presented, basing on the DCR assumption and DLIN assumption respectively.
