Lattice-based cryptography is the use of conjectured hard problems on point lattices in Rn
as the foundation for secure cryptographic systems. Attractive features of lattice cryptography …

The Internet of Things (IoT) is an information service paradigm based on the integration of
smart objects, mobile devices, and computers via the Internet. IoT technologies are key …

Abstract The National Institute of Standards and Technology is in the process of selecting
one or more public-key cryptographic algorithms through a public, competition-like process …

Smart-card based password authentication has been the most widely used two-factor
authentication (2FA) mechanism for security-critical applications (eg, e-Health, smart grid …

We propose an efficient commutative group action suitable for non-interactive key exchange
in a post-quantum setting. Our construction follows the layout of the Couveignes–Rostovtsev …

Rapid advances in quantum computing, together with the announcement by the National
Institute of Standards and Technology (NIST) to define new standards for digitalsignature …

Abstract The Fujisaki-Okamoto (FO) transformation (CRYPTO 1999 and Journal of
Cryptology 2013) turns any weakly secure public-key encryption scheme into a strongly (ie …

Background: With increased specialization of health care services and high levels of patient
mobility, accessing health care services across multiple hospitals or clinics has become very …

Abstract The National Institute of Standards and Technology is in the process of selecting
publickey cryptographic algorithms through a public, competition-like process. The new …

Post-quantum cryptosystems should be prepared before the advent of powerful quantum
computers to ensure information secure in our daily life. In 2016 a post-quantum …
