Content Introduction Abstract The CAESAR competition is an authenticated encryption algorithm competition funded by the National Institute of Standards and Technology (NIST) in 2013, aimed at soliciting authenticated encryption algorithms that outperform AES-GCM in both comprehensive performance and security, capable of providing both integrity and confidentiality. The final selected algorithms may be recommended to the … Read more
Before answering this question, let us first understand two concepts: What is the MD5 algorithm? What is an encryption algorithm? 1. MD5 Algorithm MD5 stands for Message-Digest Algorithm 5, used to ensure the integrity of information transmission. It is one of the widely used hashing algorithms in computing, and mainstream programming languages generally have an … Read more
Is there an inherent connection between passive side-channel analysis and active fault injection? Author | Shuyuan Editor | Pan Qizhi Background Introduction Side-channel analysis of cryptographic algorithms refers to the process of inferring intermediate values of cryptographic operations by collecting and analyzing the physical information leaked by cryptographic chips during computation, thereby recovering the keys. … Read more

1 Introduction DES algorithm is a common block cipher algorithm proposed by IBM in 1971. The DES algorithm is a typical representative of block ciphers and is also the most widely used symmetric encryption algorithm. This article will detail the principles and implementation process of DES. 1.1 Plaintext Plaintext refers to data that has not … 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 “é’¥”, is it pronounced “yao” or “yue”? Check the image below. 1. Symmetric Encryption As the name suggests, in symmetric encryption, … Read more
