Cryptanalysis of a code-based full-time signature
Nicolas Aragon, Marco Baldi, Jean-Christophe Deneuville +3
We present an attack against a code-based signature scheme based on the Lyubashevsky protocol that was recently proposed by Song, Huang, Mu, Wu and Wang (SHMWW). The private key in…
Galois ring isomorphism problem
Karan Khathuria
Recently, Doröz et al. (2017) proposed a new hard problem, called the finite field isomorphism problem, and constructed a fully homomorphic encryption scheme based on this problem.…
On single server private information retrieval in a coding theory perspective
Gianira N. Alfarano, Karan Khathuria, Violetta Weger
In this paper, we present a new perspective of single server private information retrieval (PIR) schemes by using the notion of linear error-correcting codes. Many of the known sin…
On the Hardness of the Lee Syndrome Decoding Problem
Violetta Weger, Karan Khathuria, Anna-Lena Horlemann +3
In this paper we study the hardness of the syndrome decoding problem over finite rings endowed with the Lee metric. We first prove that the decisional version of the problem is NP-…
