Digital Signatures for Consensus
blockchain multi-signature forward-security
font style='font-size:12px;'>
2019/3/11
We present a pairing-based signature scheme for use in blockchains that achieves substantial savings in bandwidth and storage requirements while providing strong security guarantees. Our signature sch...
Practical and Tightly-Secure Digital Signatures and Authenticated Key Exchange
Tight security digital signatures Fiat-Shamir
font style='font-size:12px;'>
2018/6/5
Tight security is increasingly gaining importance in real-world cryptography, as it allows to choose cryptographic parameters in a way that is supported by a security proof, without the need to sacrif...
On Composable Security for Digital Signatures
Digital Signatures Composable Security
font style='font-size:12px;'>
2018/1/12
A digital signature scheme (DSS), which consists of a key-generation, a signing, and a verification algorithm, is an invaluable tool in cryptography. The first and still most widely used security defi...
CRYSTALS -- Dilithium: Digital Signatures from Module Lattices
digital signatures post-quantum cryptography implementations
font style='font-size:12px;'>
2017/6/28
This paper presents Dilithium, a lattice-based signature scheme that is part of the CRYSTALS (Cryptographic Suite for Algebraic Lattices) package that will be submitted to the NIST call for post-quant...
qDSA: Small and Secure Digital Signatures with Curve-based Diffie-Hellman Key Pairs
Signatures Kummer Curve25519
font style='font-size:12px;'>
2017/6/6
qDSA is a high-speed, high-security signature scheme that facilitates implementations with a very small memory footprint, a crucial requirement for embedded systems and IoT devices, and that uses the ...
Efficient Digital Signatures From Coding Theory
Signature Coding Theory Identification
font style='font-size:12px;'>
2017/5/11
The design of an efficient code-based signature scheme is by all means still an open problem. In this paper, we propose a simple and efficient scheme following the framework detailed by Lyubashevsky t...
Quantum Tokens for Digital Signatures

The fisherman caught a quantum fish. "Fisherman, please let me go", begged the fish, "and I will grant you three wishes". The fisherman agreed. The fish gave the fisherman a quantum computer, three qu...
Digital Signatures Based on the Hardness of Ideal Lattice Problems in all Rings
lattice ideal lattice Ring-SIS
font style='font-size:12px;'>
2016/12/10
In this work, we show that the above may actually be possible. We construct a digital signature scheme based (in the random oracle model) on a simple adaptation of the Ring-SIS problem which is as har...
Digital Signatures from Symmetric-Key Primitives
post-quantum cryptography signatures block cipher
font style='font-size:12px;'>
2016/12/7
We propose practically efficient signature schemes which feature several attractive properties: (a) they only rely on the security of symmetric-key primitives (block ciphers, hash functions), and are ...
Blank Digital Signatures
Digital signature scheme blank digital signatures elliptic curves pairings polynomial commitments
font style='font-size:12px;'>
2013/4/18
In this paper we present a novel type of digital signatures, which we call blank digital signatures. The basic idea behind this scheme is that an originator can define and sign a message template, des...
On the Theory and Practice of Personal Digital Signatures
Personal Digital Signatures issuing digital signatures key-logging
font style='font-size:12px;'>
2009/6/12
We take a step towards a more realistic modeling of personal
digital signatures, where a human user, his mobile equipment, his PC and
a server are all considered as independent players in the protoc...

Practical Attacks on Digital Signatures Using MD5 Message Digest
collision hash function MD5
font style='font-size:12px;'>
2009/4/3
We use the knowledge of the single MD5 collision published by
Wang et al. [2] to show an example of a pair of binary self-extract packages
with equal MD5 checksums, whereas resulting extracted contr...
Tamper-Evident Digital Signatures；Protecting Certi¯cation Authorities Against Malware
covert channel subliminal channel tamper-evident undercover
font style='font-size:12px;'>
2009/2/8
We introduce the notion of tamper-evidence for digital signature generation in order to
defend against attacks aimed at covertly leaking secret information held by corrupted network nodes.
This is a...
