Understanding Quantum Algorithms: How They Break Modern Encryption Algorithms

The RSA encryption algorithm is the cornerstone of modern information security, widely used in network communication, data encryption, and e-commerce. However, with the rapid development of quantum computing, traditional cryptography faces unprecedented challenges. Especially in the era of Noisy Intermediate-Scale Quantum (NISQ) computing, the Variational Quantum Factorization (VQF) algorithm, based on quantum-classical hybrid methods, provides … Read more

Cryptography: Understanding the Mysteries of Codes

Of course, this behavior is very unethical, hiding behind a screen and trampling on education and law at will. However, the relevant departments have also taken timely measures to prevent such incidents from occurring frequently. Back to the point, if an intruder directly cracks passwords through technical means to disrupt classes, does this “password” have … Read more
