A Modified pqsigRM: RM Code-Based Signature Scheme
Code-based cryptography Courtois Finiasz
2019/6/12
We propose a novel signature scheme based on a modified Reed--Muller (RM) code, which reduces the signing complexity and key size compared to existing code-based signature schemes. This cheme is calle...
A Server-Assisted Hash-Based Signature Scheme
digital signatures hash functions public-key cryptography
2019/6/10
We present a practical digital signature scheme built from a cryptographic hash function and a hash-then-publish digital time- stamping scheme. We also provide a simple proof of existential unforgeabi...
A Blockchain-Assisted Hash-Based Signature Scheme
digital signatures hash functions public-key cryptography
2019/6/10
We present a server-supported, hash-based digital signature scheme. To achieve greater efficiency than current state of the art, we relax the security model somewhat. We postulate a set of design requ...

RQCS digital signatures cryptanalysis
2019/2/27
Song, Huang, Mu, and Wu proposed a new code-based signature scheme, the Rank Quasi-Cyclic Signature (RQCS) scheme (PKC 2019, Cryptology ePrint Archive 2019/053), which is based on an IND-CCA2 KEM sche...
A New Code-based Signature Scheme with Shorter Public Key
Post-Quantum Cryptography Rank Metric Codes Digital Signatures
2019/1/26
Code-based signature has been believed to be a useful authentication tool for post-quantum cryptography. There have been some attempts to construct efficient code-based signatures; however, existing c...
We describe a variation of the Schnorr-Lyubashevsky approach to devising signature schemes that is adapted to rank based cryptography. This new approach enables us to obtain a randomization of the sig...
White-Box Implementation of the Identity-Based Signature Scheme in the IEEE P1363 Standard for Public Key Cryptography
cryptographic protocols cryptographic algorithms
2018/11/19
Unlike black-box cryptography, an adversary in a white-box security model has full access to the implementation of the cryptographic algorithm. Thus, white-box implementation of cryptographic algorith...
We present here Wave the first ``hash-and-sign'' code-based signature scheme which strictly follows the GPV strategy [GPV08]. It uses the family of ternary generalized (U,U+V)(U,U+V) codes. We prove t...
In this document, we introduce PKP-DSS: a Digital Signature Scheme based on the so-called Permuted Kernel Problem (PKP). PKP is an NP-complete algebraic problem that consists of finding a kernel vecto...
Masking the GLP Lattice-Based Signature Scheme at Any Order
Side-channel Masking lattice-based signature
2018/5/2
Abstract. Recently, numerous physical attacks have been demonstrated against lattice- based schemes, often exploiting their unique properties such as the reliance on Gaussian distributions, rejection ...
Flush, Gauss, and Reload -- A Cache Attack on the BLISS Lattice-Based Signature Scheme
SCA FLUSH+RELOAD lattices
2016/3/18
We present the first side-channel attack on a lattice-based signature scheme, using the FLUSH+RELOAD cache-attack. The attack is targeted at the discrete Gaussian sampler, an important step in the Bim...

2016/1/27
In view of the expected progress in cryptanalysis it is important to find alternatives for currently
used signature schemes such as RSA and ECDSA. The most promising lattice-based signature
