Security analysis of two lightweight certificateless signature schemes
Certificateless cryptography Cryptanalysis Signature
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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 ...

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

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...

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
font style='font-size:12px;'>
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...
Protean Signature Schemes
public-key cryptography Protean Signature schemes
font style='font-size:12px;'>
2018/11/6
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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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

font style='font-size:12px;'>
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

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...
