A New Variant of the Winternitz One Time Signature Scheme Based on Graded Encoding Schemes

2019/2/28
The Winternitz one-time signature (WOTS) scheme, which can be described using a certain number of so-called ``function chains", plays an important role in the design of both stateless and stateful man...
Graded Encoding Schemes from Obfuscation
Multilinear maps graded encoding schemes indistinguishability obfuscation

2018/1/12
We construct a graded encoding scheme (GES), an approximate form of graded multilinear maps. Our construction relies on indistinguishability obfuscation, and a pairing-friendly group in which (a suita...

We construct a general-purpose indistinguishability obfuscation (IO) scheme for all polynomial-size circuits from {\em constant-degree} graded encoding schemes in the plain model, assuming the existen...
A subfield lattice attack on overstretched NTRU assumptions: Cryptanalysis of some FHE and Graded Encoding Schemes
NTRU Cryptanalysis Multilinear Maps

2016/2/23
We exploit the presence of a subfield to solve the NTRU problem for large moduli
q: norming-down the public key h to a subfield may lead to an easier lattice problem, and any
sufficiently good solut...
Implementing Candidate Graded Encoding Schemes from Ideal Lattices

font style='font-size:12px;'>
2016/1/6
Multilinear maps have become popular tools for designing cryptographic schemes
since a first approximate realisation candidate was proposed by Garg, Gentry and Halevi
(GGH). This construction was la...
