Title: Cryptographic Obfuscation: Models, Security and (Im)possibile Results
Speaker: Prof. Mingwu Zhang
Abstract: Program obfuscation is an important cryptographic primitive that hides the secrets inside a program while preserving its functionality, which has appealing applications in intellectual property protection, authentication without explicit password, digital watermark and even complex cryptographic primitives etc. However, research shows that it is impossible to obtain a program obfuscation for general-purpose functions or circuits. In this talk, we introduce the model of program obfuscation, and then analyze the possibility and impossility of the obfuscation of some functions. Also, we give some cryptographic constructions about several specific functions.
