Quantum computers are expected to break modern public key cryptography owing to Shor's
algorithm. As a result, these cryptosystems need to be replaced by quantum-resistant …

Picnic is a digital signature algorithm designed to provide security against attacks by
quantum computers. The design uses only symmetric-key primitives, and is an efficient …

Two-factor authentication provides a strong defense against account compromise. However,
traditional two-factor authentication schemes cannot provide users with much flexibility and …

Passwords are the most prevalent authentication mechanism, and proliferate on nearly
every new web service. As users are overloaded with the tasks of managing dozens even …

Post-quantum cryptography has received increased attention in recent years, in particular,
due to the standardization effort by NIST. One of the second-round candidates in the NIST …

Abstract HQC is an IND-CCA2 KEM running for standardization in NIST's post-quantum
cryptography project and has advanced to the second round. It is a code-based scheme in …

The high degree of automation demanded in the automotive industry has turned vehicles
into powerful mobile computing platforms. Various types of data are collected, distributed …

There appears to be a widespread belief that some processes of selecting cryptosystems
are less risky than other processes. As a case study of quantifying the difference in risks, this …

Algebraic digital signature algorithms with a hidden group, which are based on the
computational difficulty of finding a solution to a system of many quadratic equations with …

The protection of data is essential in this digitized world and hence the need for
cryptographic techniques to aid in this process. Cryptography in general helps achieve three …
