WebPost-Quantum Cryptography - 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 … WebCryptography is the mathematical foundation on which one builds secure systems. It studies ways of securely storing, transmitting, and processing information. Understanding what cryptographic primitives can do, and how they can be composed together, is necessary to build secure systems, but not su cient.
