This article is contributed by the ChaMd5 Security Team IOT Group. This is a summary of the theoretical knowledge learned recently about side-channel attacks and fault injection. If there are any mistakes or areas for improvement, I hope experts will correct me. First, let’s introduce several common encryption algorithms. Encryption Algorithms RSA Encryption Algorithm RSA … 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 1.1 Ransomware Ransomware is a type of malicious software that runs on computers, kidnapping user files and rendering user data assets or computing resources unusable, and extorting money from users as a condition for restoring access. These user data assets include various files such as documents, databases, source code, images, and compressed files. … Read more
Follow “Script Home” and join millions of developers Author | kiba518 Produced by | Script Home (ID: jb51net) Introduction This article mainly explains the commonly used encryption algorithms in C#. MD5 Encryption MD5 encryption is the most common encryption method. Since MD5 is irreversible, many systems store passwords using MD5 encryption. Although MD5 cannot be … Read more

Java Technology Stack www.javastack.cn Follow to read more quality articles Encryption algorithms can generally be divided into: reversible encryption and irreversible encryption. Reversible encryption can further be divided into: symmetric encryption and asymmetric encryption. 1. Irreversible Encryption Common irreversible encryption algorithms include MD5, HMAC, SHA1, SHA-224, SHA-256, SHA-384, and SHA-512. Among them, SHA-224, SHA-256, SHA-384, … Read more
A Revolutionary Algorithm Earth-Shattering A cryptographic algorithm that can only be cracked by computational power 1 The History of Cryptography 5th Century BC, the ancient Greeks used a stick called scytale to transmit encrypted messages. To encrypt, a strip of paper was wrapped around the stick, and the message was written horizontally along the stick. … Read more
