后量子密码

摘 要：The most widely used nowadays are the number theoretical based cryptosystems such as RSA, DSA, and ECC. However, due to Peter Shor's Algorithm, such cryptosystems would become insecure if a large Quantum computer is built. We need to develop a new family of cryptosystems that can resist quantum computers attacks. Researchers usually use Post-Quantum Cryptography (PQC) to denote this new...
