Author丨labuladong Source丨labuladong The “password” mentioned here is not the same concept as the passwords we use in daily life. The cryptographic algorithms discussed in this article mainly address the issues of encryption and decryption in information transmission.We must assume that the data transmission process is insecure, and all information is being eavesdropped on, so the … Read more
ClickBlue TextFollow Us Abstract: The symmetric and asymmetric cryptographic systems each have their own advantages and disadvantages.Exploring a hybrid cryptographic system that combines both, retaining their advantages while maximizing the elimination of their disadvantages, is of great significance for the efficiency and security of modern network communication.Using asymmetric encryption to protect symmetric key is a … Read more
Source: https://www.biaodianfu.com/aes.html The Data Encryption Standard (DES) has a key length of 56 bits, resulting in a theoretical security strength of 256. However, the late 20th century was a period of rapid development in computing, and advancements in component manufacturing technology led to increasing computational power, making DES insufficiently secure. On January 2, 1997, the … Read more
