Post-Quantum Cryptography in the automobile sector: • Post-quantum cryptography (PQC), also referred to as quantum-resistance cryptography, is an encryption approach that aims to secure a system against a cryptanalytic attack by a quantum computer through cryptographic algorithms. • The demand for PQC is increasing splendidly across all industries, including electronics, automotive, finance, healthcare, etc., owing to the confined safety and security of data provided by existing renowned algorithms. • PQC employs various algorithms comprising Hash-Based Cryptography, Code-Based Cryptography, Lattice-Based Cryptography, Multivariate Cryptography and many more.
