Post-Quantum Cryptosystems for Internet-of-Things: A Survey on Lattice-Based Algorithms

The latest quantum computers have the ability to solve incredibly complex classical cryptography equations particularly decode secret encrypted keys and making network vulnerable hacking. They can mathematical problems almost instantaneously compared billions of years computation needed by traditional computing machines. Researchers advocate development novel strategies include data encryption in post-quantum era. Lattices been widely used cryptography, somewhat peculiarly, these algorithms both; (a) cryptoanalysis using lattice approximation break cryptosystems; (b) computationally hard (non-deterministic polynomial time hardness) construct stable cryptographic functions. Most dominant features lattice-based (LBC), which holds it ahead league, resistance attack vectors, high concurrent performance, parallelism, security under worst-case intractability assumptions, solutions long-standing open cryptography. While methods offer possible for cryptosytems theory experimentation, their implementation energy-restricted Internet-of-Things (IoT) devices requires careful study regular implantation its simplification lightweight (LW-LBC). This streamlined algorithm is ideal levelled IoT device security. key aim this survey was provide scientific community with comprehensive information on elementary facts, as well address real-time implementation, hardware architecture, problems, significance networks.
