I never expected that the news about “Front Desk” and “88888888” would generate over 5,000 comments (on Weibo), with most discussions revolving around whether it would automatically connect to “Front Desk”. Therefore, I unboxed different brands of wireless routers one by one to conduct connection tests, using three different smartphones for testing (the Mate20 is … Read more
Rust Cryptography Libraries: A Comprehensive Guide Cryptography refers to the process of converting information into a secure format, primarily achieved through encryption. It ensures that data transmitted over the network is secure and reliable. Although Rust has a random number generator, the most commonly used suite today is OpenSSL. As this guide shows, the Rust … Read more
According to Breaking Defense, Northrop Grumman will begin testing a new hardware/software prototype for the Space Force next spring, designed to protect large interconnected satellite networks from cyberattacks. This prototype, named the Space End Crypto Unit (ECU), is being developed by Aeronix and is scheduled for delivery in 2024. On June 7, Northrop Grumman (NYSE: … Read more
In the digital age, home networks are as essential as water and electricity in our homes. We rely on them for work, study, entertainment, and socializing. However, with the widespread use of the internet, the security threats facing home networks are increasing, and routers, as the core hub of home networks, have become prime targets … Read more
Introduction to HTTP Protocol The HTTP protocol is a text-based transmission protocol that operates at the application layer of the OSI network model. The HTTP protocol communicates through request-response interactions between clients and servers. The protocol has been split from the previous RFC 2616 into six separate protocol specifications (RFC 7230, RFC 7231, RFC 7232, … Read more
Recently, I worked on a project that involved selecting some encryption algorithms, and I would like to summarize them here to deepen our understanding of encryption. The most commonly used encryption algorithms can be summarized as one-way encryption and two-way encryption. They are quite simple and not difficult to understand. However, I believe it is … Read more
Application of Encryption Algorithms in PLCs: Protecting Intellectual Property and Data Security Introduction: New Security Challenges in Industrial Control Systems With the advancement of Industry 4.0, PLC systems are increasingly connected to enterprise networks and even the internet. This connectivity enhances efficiency but also brings unprecedented security risks to the systems. In a automotive parts … Read more
Implementing a Simple Encryption and Decryption Tool in C In today’s article, we will implement a simple encryption and decryption tool using the C programming language. This tool is based on a very basic character substitution algorithm, allowing users to input a plaintext, encrypt it using a defined method, and then decrypt it back through … Read more
Click the blue text “ShunYun Multi-Physical Field Simulation” Explore advanced algorithm engines Elliptic Curve Cryptography (ECC) is a highly regarded topic. ECC is a public key encryption algorithm that utilizes points on an elliptic curve for encryption and decryption operations. Compared to traditional RSA algorithms, ECC offers greater efficiency and security by using shorter key … Read more
ref: RFC3961 An encryption mechanism must define the following properties and operations: 1. Protocol Key Format Specifies which characters (octet string) can appear in a valid key. For keys that require special encoding, it must specify how to encode them. For encryption mechanisms that don’t have <span>perfectly dense key spaces</span>, this will describe the representation … Read more
