Security analysis of two lightweight certi ficateless signature schemes
Certificateless cryptography Cryptanalysis Signature
2019/8/19
Certificateless cryptography can be considered as an intermediate solution to overcome the issues in traditional public key infrastructure (PKI) and identity-based public key cryptography (ID-PKC). Th...
A New Approach to Constructing Digital Signature Schemes (Extended Paper)
digital signatures hash functions public-key cryptography
2019/6/10
A new hash-based, server-supported digital signature scheme was proposed recently. We decompose the concept into forward-resistant tags and a generic cryptographic time-stamping service. Based on the ...
Subliminal channels in post-quantum digital signature schemes
Subliminal channels post-quantum digital signatures
2019/5/29
We analyze the digital signatures schemes submitted to NIST's Post-Quantum Cryptography Standardization Project in search for subliminal channels.
Evaluation of Code-based Signature Schemes
post-quantum cryptography code-based cryptography signature scheme
2019/5/23
Code-based cryptographic schemes recently raised to prominence as quantum-safe alternatives to the currently employed number-theoretic constructions, which do not resist quantum attacks. In this artic...
On sigma protocols with helper for MQ and PKP, fishy signature schemes and more
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...
Efficient Fully-Leakage Resilient One-More Signature Schemes
leakage resilient signature schemes
2018/11/30
In a recent paper Faonio, Nielsen and Venturi (ICALP 2015) gave new constructions of leakage-resilient signature schemes. The signature schemes proposed remain unforgeable against an adversary leaking...
We introduce the notion of Protean Signature schemes. This novel type of signature scheme allows to remove and edit signer-chosen parts of signed messages by a semi-trusted third party simultaneously....
Improved Signature Schemes for Secure Multi-Party Computation with Certified Inputs
cryptographic protocols Certified Inputs
2018/8/16
The motivation for this work comes from the need to strengthen security of secure multi-party protocols with the ability to guarantee that the participants provide their truthful inputs in the computa...
Public Key Compression for Constrained Linear Signature Schemes
digital signatures post-quantum quantum random oracle model
2018/7/16
We formalize the notion of a constrained linear trapdoor as an abstract strategy for the generation of signature schemes, concrete instantiations of which can be found in MQ-based, code-based, and lat...
Certificateless Public Key Signature Schemes from Standard Algorithms
Certificateless PKC Implicit certificate Signature
2018/5/2
Certificateless public key cryptography (CL-PKC) is designed to have succinct public key management without using certificates at the same time avoid the key-escrow attribute in the identity-based cry...
Signature Schemes with a Fuzzy Private Key
Fuzzy Signature Public Biometric Infrastructure
2017/12/13
In this paper, we introduce a new concept of digital signature that we call \emph{fuzzy signature}, which is a signature scheme that uses a noisy string such as biometric data as a private key, but \e...
Attacking Deterministic Signature Schemes using Fault Attacks
Deterministic signatures EdDSA fault attack
2017/10/19
Many digital signature schemes rely on random numbers that are unique and non-predictable per signature. Failures of random number generators may have catastrophic effects such as compromising private...
A tight security reduction in the quantum random oracle model for code-based signature schemes
Quantum Random Oracle Quantum-Safe Cryptography Code-Based Cryptography
2017/9/28
Quantum secure signature schemes have a lot of attention recently, in particular because of the NIST call to standardize quantum safe cryptography. However, only few signature schemes can have concret...
Bounding the cache-side-channel leakage of lattice-based signature schemes using program semantics
cache side channels lattice-based signature schemes program analysis
2017/9/28
In contrast to classical signature schemes, such as RSA or ECDSA signatures, the lattice-based signature scheme ring-TESLA is expected to be resistant even against quantum adversaries. Due to a recent...
Multi-Designated Verifiers Signature Schemes with Threshold Verifiability: Generic Pattern and a Concrete Scheme in the Standard Model
Digital Signature Designated Verifier Signature Scheme Multi-Designated Verifiers Signature Scheme
2017/8/28
In a designated verifier signature (DVS) scheme, the validity of the signature can only be verified by a designated entity chosen by the signer. Furthermore, the designated entity cannot convince a th...
