If you find this article beneficial, feel free to share it. In this digital age, every online transaction and every encrypted email relies on a sophisticated encryption system. Today, I want to talk about the RSA algorithm (Rivest-Shamir-Adleman, named after its three inventors), the foundation of public key encryption that builds a security barrier in … Read more
This article introduces commonly used cryptographic algorithms in daily development. abstract.png Classical Cryptography Classical cryptography typically employs simple techniques such as substitution (replacing letters in plaintext with other letters) and transposition (rearranging the order of letters in plaintext), without the need for complex machines or algorithms. Therefore, its security is insufficient and easily compromised. Caesar … Read more
1. Definition of Asymmetric Encryption Algorithms An asymmetric encryption algorithm is a type of encryption technology that uses a pair of keys for encryption and decryption. Unlike symmetric encryption, asymmetric encryption uses two keys: a public key for encrypting data and a private key for decrypting it. Only the recipient who possesses the private key … Read more

RSA (Rivest-Shamir-Adleman) is a classic asymmetric encryption algorithm proposed by three cryptographers Ron Rivest, Adi Shamir, and Leonard Adleman in 1977. Its core function is to achieve secure communication through public key encryption and private key decryption, widely used in digital signatures, SSL/TLS protocols, data encryption, and other fields. Key Generation Principle of RSA Significance … Read more
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
