Post-Quantum Cryptography for Embedded Systems: Challenges and Accelerator Integration over RISC-V Architecture

Introduction Information security has taken an increasingly crucial and pervasive role, particularly for embedded systems, which are low-power, resource-constrained devices involved in critical applications such as automotive, IoT and industrial...

TelsyInTouch: secure mobile conversations

31 Mar

In the world of information and interconnection, where both workers and private citizens are exposed to a multitude of cyber risks ranging from malware, computer fraud, theft of intellectual property...

Multivariate signatures based on identification schemes

15 Feb

Introduction The goal of an identification protocol is to enable the verification of someone’s identity. More specifically, a Prover must demonstrate to an interlocutor, called the Verifier, that they...

UOV and its Variants: Digital Signatures Based on Multivariate Systems

24 Nov

In the previous exploration of multivariate cryptography, we examined how systems of polynomial equations over finite fields can form the basis for cryptographic schemes resistant to quantum computing attacks. The...

In the office, on the road, at home, and in many other places, we often use tools and devices constantly connected to the Internet. This condition has greatly increased...

Falcon: digital signature based on NTRU

31 Jul

Introduction NIST’s Post-Quantum standardization process has identified two cryptographic schemes based on lattice theory within digital signatures: CRYSTALS-Dilithium and Falcon. Within modern cryptographic communication protocols, these solutions will replace the...

One-Way and Trapdoor Functions: The Heart Of Modern Encryption

14 Dec

Introduction A one-way function is, by definition, a mathematical function that is easy to calculate but computationally difficult to invert. In other words, inverting a one-way function is equivalent to...
