zero knowledge Post-Quantum digital signatures Multivariate cryptography
2019/5/21
We then remove the helper from the protocol with a "cut-and-choose" protocol and we apply the Fiat-Shamir transform to obtain signature schemes with security proof in the QROM. We show that the result...
BEARZ Attack FALCON: Implementation Attacks with Countermeasures on the FALCON signature scheme

Post-quantum cryptography is an important and growing area of research due to the threat of quantum computers, as recognised by the National Institute of Standards and Technology (NIST) recent call fo...
A Method to Reduce the Key Size of UOV Signature Scheme
digital signatures public-key cryptography
2019/5/13
Multivariate public key signature scheme has a good performance on speed and signature size. But most of them have a huge public key size. In this paper, we propose a new method to reduce the public k...
With the rapid development of quantum technologies, quantum-safe cryptography has found significant attention. Hash-based signature schemes have been in particular of interest because of (i) the impor...
Hierarchical Attribute-based Signatures: Short Keys and Optimal Signature Length
Attribute-based Signatures delegation hierarchy path anonymity
2019/4/16
With Attribute-based Signatures (ABS) users can simultaneously sign messages and prove compliance of their attributes, issued by designated attribute authorities, with some verification policy. Neithe...
Generic Construction of Linkable Ring Signature

2019/4/11
We propose a generic construction of linkable ring signature from any compatible ring signature scheme and one-time signature scheme. Our construction has both theoretical and practical interest. In t...
A Traceable Ring Signature Scheme based on Coding Theory
cryptographic protocols digital signatures
2019/4/1
Traceable ring signatures are a variant of ring signatures which allows the identity of a user to be revealed, when it signs two different messages with respect to the same group of users. It has appl...

Group signature Cryptanalysis ISO/IEC 20008-2 SGX
2019/3/18
In ISO/IEC 20008-2, several anonymous digital signature schemes are specified. Among these, the scheme denoted as Mechanism 6, is the only plain group signature scheme that does not aim at providing a...
A New Variant of the Winternitz One Time Signature Scheme Based on Graded Encoding Schemes
graded encoding schemes multi-linear maps GDL problem
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...

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...
A Revocable Group Signature Scheme with Scalability from Simple Assumptions and Its Application to Identity Management
Group Signatures Anonymity Revocation
2019/1/26
Group signatures are signatures providing signer anonymity where signers can produce signatures on behalf of the group that they belong to. Although such anonymity is quite attractive considering priv...
