Cryptanalysis of CLT13 Multilinear Maps with Independent Slots
Multilinear maps lattice cryptanalysis
2019/3/21
Many constructions based on multilinear maps require independent slots in the plaintext, so that multiple computations can be performed in parallel over the slots. Such constructions are usually based...
New Multilinear Maps from CLT13 with Provable Security Against Zeroizing Attacks
multilinear maps obfuscation CLT13
2017/9/28
We devise the first weak multilinear map model for CLT13 multilinear maps (Coron et al., CRYPTO 2013) that captures all known classical polynomial-time attacks on the maps. We then show important appl...
Zeroizing Attacks on Indistinguishability Obfuscation over CLT13
Multilinear Maps CLT13 Indistinguishability Obfuscation
2016/12/8
In this work, we describe a new polynomial-time attack on the multilinear maps of Coron,
Lepoint, and Tibouchi (CLT13), when used in candidate iO schemes. More specifically, we show that
given the o...
