Virtual black-box obfuscation for all circuits via generic graded encoding
Z Brakerski, GN Rothblum - Theory of Cryptography Conference, 2014 - Springer
We present a new general-purpose obfuscator for all polynomial size circuits. The
obfuscator uses graded encoding schemes, a generalization of multilinear maps. We prove …

Proofs of restricted shuffles
B Terelius, D Wikström - … : Third International Conference on Cryptology in …, 2010 - Springer
A proof of a shuffle is a zero-knowledge proof that one list of ciphertexts is a permutation and
re-encryption of another list of ciphertexts. We call a shuffle restricted if the permutation is …
