Quantum Attacks against Indistinguishablility Obfuscators Proved Secure in the Weak Multilinear Map Model
Cryptanalysis Obfuscation
2018/6/5
We present a quantum polynomial time attack against the GMMSSZ branching program obfuscator of Garg et al. (TCC'16), when instantiated with the GGH13 multilinear map of Garg et al. (EUROCRYPT'13). Thi...
All known candidate indistinguishibility obfuscation (iO) schemes rely on candidate multilinear maps. Until recently, the strongest proofs of security available for iO candidates were in a generic mod...
