Attacks and Solutions in Cryptography


The advancement in high-performance computing and the dawn of quantum computing drive the need for novel designs of cryptographic algorithms that are secure against potential future adversaries. The emergence of the Internet of things (IoT) also propels the designing of lightweight cryptography suitable for resource-constrained edge devices. It is of paramount importance to analyze the security and potential weakness of different crypto-primitives under various applications to ensure confidentiality, integrity, authentication, and nonrepudiation for secure communications. In addition, Shor's factoring algorithm exposes the possible vulnerabilities of well-established public key infrastructure (PKI) such as RSA when facing quantum computers. The lattice-based learning with errors (LWE) is one of the promising candidates for Post-Quantum Cryptography (PQC), thwarting the cryptanalysis efforts with advanced quantum machines.
