Cryptanalyses of Branching Program Obfuscations over GGH13 Multilinear Map from NTRU Attack
Obfuscation multilinear maps graded encoding schemes
2018/5/11
In this paper, we propose cryptanalyses of all existing indistinguishability obfuscation (iO) candidates based on branching programs (BP) over GGH13 multilinear map. To achieve this, we introduce two ...
Cryptanalyses of Candidate Branching Program Obfuscators
Cryptanalysis Graded-Encoding Obfuscation
2016/12/8
We describe new cryptanalytic attacks on the candidate branching-program obfuscator proposed by
Garg, Gentry, Halevi, Raykova, Sahai and Waters (GGHRSW) using the GGH13 graded encoding, and its
vari...
