Understanding RSA Algorithm Principles (Part 1)

Understanding RSA Algorithm Principles (Part 1)

If you ask me, which algorithm is the most important? I might answer “Public Key Encryption Algorithm“. Because it is the cornerstone of computer communication security, ensuring that encrypted data cannot be cracked. You can imagine the consequences if credit card transactions are compromised. Before getting into the main topic, let me briefly introduce what … Read more

Obfuscation Techniques: The Safest Way to Encrypt Code

Obfuscation Techniques: The Safest Way to Encrypt Code

For decades, computer scientists have sought to verify whether there exists an absolutely secure method to encrypt computer programs, rendering them uncrackable during use. At the end of 2020, several scholars successfully discovered an encryption method that prevents computer users from cracking programs by obtaining the code. Encrypting Program Code First, It Must Be Obfuscated … Read more

Math-Based Encryption and Decryption Game for Kids

Math-Based Encryption and Decryption Game for Kids

Recently, I’ve been discussing addition and subtraction with regrouping within 20 in our activity group. We have progressed from understanding numbers within 100, practicing making ten, basic methods of regrouping, to the second round of learning numbers within 10, and now we’ve reached more strategies for calculations within 20. In the past couple of days, … Read more

Tor Adds New Encryption Algorithm for Enhanced Security

Tor Adds New Encryption Algorithm for Enhanced Security

The Tor browser, known for its anonymity, is striving to reach new heights in the pursuit of encryption keys. To generate encryption keys that are hard to crack, it is necessary to innovate and upgrade the random algorithms. A key is a parameter that is input data in the algorithm that converts plaintext to ciphertext … Read more

Understanding HTTPS and Its Encryption Principles

Understanding HTTPS and Its Encryption Principles

HTTPS (full name: Hypertext Transfer Protocol Secure, is a secure version of HTTP designed with security in mind. This article will delve into its principles. 1 Why HTTPS is Necessary The reason for using HTTPS is quite simple: it is due to the insecurity of HTTP. When we send sensitive data to a server (such … Read more

Introduction to Information Security and Cryptography

Introduction to Information Security and Cryptography

This article provides a preliminary understanding of the field of information security. 1. Briefly describe security attacks, security mechanisms, and security services. Security attack: Any act that jeopardizes the security of an information system. Security mechanism: A process used to detect, prevent attacks, or recover from an attack state to a normal state. Security service … Read more
