Crypto: defines the rules of digital world. Imagine a society without rules. My goal: give you an overview of the very basic concepts. Get you interested. Prepare you to dive deeper on your own. 5. Cryptography and computer security: very fast growing topics within computer science. Online attackers are growing in sophistication.
Post-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 ...
Sep 19, 2014 · Cryptography • Cryptography is the technique of secret writing. • A cipher is a method of secret writing. • The purpose is to convert an intelligible message, referred to as plaintext, into apparently random nonsense text, referred to as ciphertext. • The encryption process consists of an algorithm and a key.
