Human-readable Proof of the Related-Key Security of AES-128
Abstract. The related-key model is now considered an important scenario for block cipher security and many schemes were broken in this model, even AES-192 and AES-256. Recently wer...

On Statistically Secure Obfuscation with Approximate Correctness
Goldwasser and Rothblum (TCC ’07) prove that statistical indistinguishability obfuscation (iO) cannot exist if the obfuscator must maintain perfect correctness (under a widely b...

Pseudorandom Functions in Almost Constant Depth from Low-Noise LPN
Pseudorandom functions (PRFs) play a central role in symmetric cryptography. While in principle they can be built from any one-way functions by going through the generic HILL (SIC...

Adaptively Secure Identity-Based Encryption from Lattices with Asymptotically Shorter Public Parameters
In this paper, we present two new adaptively secure identity-based encryption (IBE) schemes from lattices. The size of the public parameters, ciphertexts, and private keys are ˜O...
