The historical development of cryptographic algorithms is a reflection of the continuous struggle and progress of human intelligence and technology. Below is a detailed chronological introduction: 1. Classical Cryptography (Before 5th Century) Caesar Cipher (1st Century BC) The earliest monoalphabetic substitution cipher, which encrypts by shifting the alphabet by a fixed number of positions (e.g., … Read more
Homomorphic encryption (HE) is a special encryption mode in cryptography that satisfies the property of homomorphic operations on ciphertexts. This means that after data is homomorphically encrypted, specific calculations can be performed on the ciphertext, and the result of these calculations, when subjected to corresponding homomorphic decryption, will be equivalent to performing the same calculations … Read more
