Indistinguishability Obfuscation Without Multilinear Maps: New Paradigms via Low Degree Weak Pseudorandomness and Security Amplification
PFG iO
2019/6/4
The existence of secure indistinguishability obfuscators (iO) has far-reaching implications, significantly expanding the scope of problems amenable to cryptographic study. All known approaches to cons...
Security Amplification against Meet-in-the-Middle Attacks Using Whitening
Block cipher meet-in-the-middle attack provable security
2014/3/7
In this paper we introduce a model for studying meet-in-the-middle attacks on block ciphers, and a simple block cipher construction provably resistant to such attacks in this model. A side-result of t...
