Leakage Resilient Encryption Against Adaptive Chosen Ciphertext Attack
YU Qi-hon · Computer and Modernization · 2013
Recently,a lot of attacks leak some important information which should be kept secret absolutely,so the security of many traditional cryptosystems is broken. Since 2009,designing cryptosystems which are resilient to leakage gets more and more attention. On the basis of an identify-based leakage resilient CPA secure encryption,the paper associates with a strong one-time true simulation extractable NIZK,ultimately gains an identify-based leakage resilient CCA secure encryption,which improves the security.
