Bouncy Castle: The Versatile Encryption Library Hello everyone! Today I want to share with you a very powerful encryption library in both Java and C# – Bouncy Castle. As a cryptography enthusiast, I particularly love this library because it is like a treasure chest that contains almost all commonly used encryption algorithms. Whether it’s simple … 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
Encryption Algorithms: Data Security Assurance for Microcontrollers and PLCs In industrial automation systems, data security is a critical issue that cannot be ignored. Whether it is a microcontroller or a programmable logic controller (PLC), they often need to handle and transmit important data such as production parameters, quality records, and machine status. If this data … Read more
(Legal Education) ⚠️ Decrypting encryption algorithms is illegal unless done in a legally authorized environment for research and educational purposes ⚠️ Understanding Encryption Algorithms – Conduct an in-depth study of the target encryption algorithm’s workings, mathematical foundations, and encryption processes. Collecting Encrypted Data – Obtain a large sample of data encrypted using the specified encryption … Read more
JCL: The Alchemist of Java Encryption Algorithms! Hello, friends! Today, Niu Ge will talk to you about the popular topic of Java encryption algorithms. Do you remember how confused I was the first time I encountered encryption algorithms when I transitioned from testing to Java? It was like stepping into the kitchen for the first … Read more
There are two sayings: 1) Algorithms and data structures are an important part of programming. If you lose algorithms and data structures, you lose everything. 2) Programming is algorithms and data structures; algorithms and data structures are the soul of programming. Note that this is not my own statement, but a summary from countless programmers. … Read more
According to MEMS Consulting, researchers from the Holst Center in Belgium’s IMEC and the Netherlands’ TNO have demonstrated a novel flexible, large-area sensor technology for detecting fingerprints and palm prints. This new sensor is less than 0.2 millimeters thick and does not have bulky prisms or moving parts, allowing it to be embedded in objects … Read more
In a controlled environment, preventing accidental errors and hardware failures is sufficient to achieve secure behavior. If an unrecoverable situation is detected, the system can switch to a limited or non-functional state, but it remains safe. In uncontrolled environments, various forms of attacks can jeopardize the security of the system. Only by considering security at … Read more
Due to the uniqueness of embedded systems, there are many security threats. Firstly, because embedded systems have limited resources, with small RAM and ROM and limited processing speed, they cannot implement multiple security defense measures simultaneously, making them vulnerable to attacks. Secondly, the diverse deployment environments of embedded systems, such as industrial production environments, medical … Read more
1. What is Cybersecurity? Cybersecurity includes network software security, network device security, and network information security, which refers to protecting the hardware, software, and data in network systems from accidental or malicious changes, destruction, or leakage, ensuring that the system can operate reliably, continuously, and normally, with uninterrupted network services. For example, certain official websites … Read more
