Cryptographic (crypto) algorithms are the essential ingredients of all secure systems: crypto
hash functions and encryption algorithms, for example, can guarantee properties such as …

We demonstrate that a passive network attacker can opportunistically obtain private RSA
host keys from an SSH server that experiences a naturally arising fault during signature …

We carry out the first provable security analysis of the new FIDO2 protocols, the promising
FIDO Alliance's proposal for a standard for passwordless user authentication. Our analysis …

We consider the theoretically sound selection of cryptographic parameters, such as the size
of algebraic groups or RSA keys, for TLS 1.3 in practice. While prior works gave security …

The standard definition of security for digital signatures-existential unforgeability-does not
ensure certain properties that protocol designers might expect. For example, in many …

It is well known in the cryptographic literature that the most common digital signature
schemes used in practice can fail catastrophically in the presence of faults during …

The standard security notion for digital signatures is “single-challenge”(SC) EUF-CMA
security, where the adversary outputs a single message-signature pair and “wins” if it is a …

The area of computational cryptography is dedicated to the development of effective
methods in algorithmic number theory that improve implementation of cryptosystems or …

In this study, we revisit the RSA public key cryptosystem in some special case of Boneh and
Durfee's attack when the private key d assumes to be larger than the public key e. The attack …

Abstract Supervisory Control and Data Acquisition (SCADA) systems are essential for
monitoring and controlling a country's Critical Infrastructures (CI) such as electrical power …
