Modeling Memory Faults in Signature and Encryption Schemes
fault attacks security model fault resilience deterministic signatures
<
2019/9/19
Memory fault attacks, inducing errors in computations, have been an ever-evolving threat to cryptographic schemes since their discovery for cryptography by Boneh et al. (Eurocrypt 1997). Initially req...
An efficient and secure ID-based multi-proxy multi-signature scheme based on lattice

<
2019/9/16
Multi-proxy multi-signature schemes are useful in distributed networks, where a group of users cooperatively could delegate their administrative rights to the users of another group, who are authorize...
Security analysis of two lightweight certificateless signature schemes

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...
Abstract. The extremely efficient Rabin-Williams signature scheme relies on decryption of a quadratic equation in order to retrieve the original message. Customarily, square roots are found using the ...

2019/8/6
In 2017 Kyung-Ah Shim et al proposed a multivariate signature scheme called Himq-3 which is a submission to National Institute of Standards and Technology (NIST) standardization process of post-quantu...
The Simplest Multi-key Linearly Homomorphic Signature Scheme

We consider the problem of outsourcing computation on data authenticated by different users. Our aim is to describe and implement the simplest possible solution to provide data integrity in cloud-base...
A publicly verifiable quantum blind signature scheme without entanglement based on asymmetric cryptography
Undeniable quantum signature scheme Impersonation attack Quantum asymmetric cryptography
<
2019/7/15
In recent years, several cryptographic scholars have proposed quantum blind signature schemes. However, their methods require the signatories and the inspectors to share common keys in advance, which ...

2019/6/26
In this paper, we introduce a new construction of lattice-based reusable fuzzy signature for remote user authentication that is secure against quantum computers. We define formal security models for t...
A Modified pqsigRM: RM Code-Based Signature Scheme

2019/6/12
We propose a novel signature scheme based on a modified Reed--Muller (RM) code, which reduces the signing complexity and key size compared to existing code-based signature schemes. This cheme is calle...
A Server-Assisted Hash-Based Signature Scheme
