History Before 1976, the encryption world mainly used Symmetric-key algorithms. Symmetric encryption has a troublesome problem: when parties A and B communicate, A must inform B of the encryption rules; otherwise, decryption is impossible. Is it possible to ensure the security of key storage and transmission? In 1976, two American computer scientists, Whitfield Diffie and … Read more
This article attempts to discuss the evolution of cryptographic algorithms, which are closely related to our online lives, from ancient to modern times, and to elaborate on the key cryptographic algorithms that emerged throughout this process, leading everyone to understand the fascinating algorithms behind them. — Anhua Jinhui Article Navigation ◈ How Did Ancient People … Read more
Privacy protection? It’s not to scare everyone; information is transparent, but we should still try to maintain personal privacy. Today, we will learn about symmetric encryption and asymmetric encryption. First, let’s read this character “钥”, is it pronounced “yao” or “yue”? Check the image below. 1. Symmetric Encryption As the name suggests, in symmetric encryption, … Read more
Today, we will introduce commonly used encryption algorithms, their classifications, and applications. 1. Symmetric Encryption Algorithms Symmetric means that both parties using this encryption method use the same key for encryption and decryption. The key is the instruction that controls the encryption and decryption process. The algorithm is a set of rules that specifies how … Read more
