On the Incoercibility of Digital Signatures
2023 IEEE 36th Computer Security Foundations Symposium (CSF), 2023We introduce incoercible digital signature schemes, a variant of a standard digital signature. Incoercible signatures enable signers, when coerced to produce a signature for a message chosen by an attacker, to generate fake signatures that are indistinguishable from real signatures, even if the signer is compelled to reveal their full history ...

This paper introduces four new digital signature schemes for computer communication networks. These involve one or more arbitrators who validate and authenticate messages and signatures without having access to the actual contents of the messages.

On the Incremental Digital Signatures
2018 17th IEEE International Conference On Trust, Security And Privacy In Computing And Communications/ 12th IEEE International Conference On Big Data Science And Engineering (TrustCom/BigDataSE), 2018The purpose of incremental cryptography is to enable updates of cryptographic forms of documents undergoing modifications, more efficiently than if we had to recompute them from scratch. This paper defines a framework for securely using a variant of the incremental hash function designed by Goi, Siddiqi and Chuah.

Security Arguments for Digital Signatures and Blind Signatures
Journal of Cryptology, 2000This paper proves the security of a large class of signature schemes in the so-called random oracle model. This model assumes that the hash function used in a signature scheme behaves as a random function. However, it has been shown that there exist (contrived) schemes that are provably secure in the random oracle model, but not when used with a real ...

In this article, the author describes three digital signature algorithms that have been approved by the National Institute of Standards and Technology and which have also been standardized by a number of other organizations, including ISO, ANSI, and IEEE. Two additional digital signature algorithms are also discussed.

Electronic signature based on digital signature and digital watermarking
2012 5th International Congress on Image and Signal Processing, 2012In this paper, an electronic signature algorithm, using a combined technology of digital signature, digital watermarking and time stamp, is presented. In this algorithm timestamp information is added to digital signature data, improving the signature safety and anti- offensive.

On the Security of the Digital Signature Algorithm
Designs, Codes and Cryptography, 2002The authors develop a new key-recovery attack against the Digital Signature Algorithm (DSA). It is a variant of known attacks by Boneh et al. and is also based on lattice basis reduction techniques. They prove that the system will be insecure if half of the total number of bits in the secret and ephemeral keys (or in two ephemeral keys) are known ...

Improved digital signature algorithm
IEEE Transactions on Computers, 1995Summary: A digital signature algorithm is developed which is an improved version of the Digital Signature Algorithm proposed by the NIST. The security of the improved version is the same as the original one while it benefits the signature signer and performs more efficiently.
