报告摘要Security reduction is a very popular approach for proving security in public-key cryptography. With security reduction, roughly speaking, we can show that breaking a proposed scheme is as difficult as solving a mathematical hard problem. However, how to program a correct security reduction using an adversary’s adaptive attack is rather complicated. The reason is that there is no universal security reduction for all proposed schemes. In this talk, for a cryptosystem, I will introduce how to define algorithms, how to define security models and how to program a security reduction.
