Introduction The currently popular MCUs mainly fall into two categories: ARM and DSP. Among the many manufacturers of DSP, TI (Texas Instruments) is one of the important leaders in the DSP chip field. CCS is an integrated development environment (IDE) software designed for Texas Instruments (TI) processors and microcontrollers. CCS provides developers with a complete … Read more
1. Overview Xilinx FPGAs starting from the 7 series have on-chip Advanced Encryption Standard (AES) decryption logic, providing a high level of design security. Encrypted Xilinx FPGA designs cannot be copied or reverse-engineered for other FPGAs.The Xilinx FPGA responsible for encryption uses an AES system consisting of software-based bitstream encryption and on-chip bitstream decryption, with … Read more
01 “Passwords” and “Passcodes” The term “password” mentioned in real life, such as the boot “password”, WeChat “password”, and bank card payment “password”, actually refers to passcodes. A passcode is merely a “ticket” to access personal computers, mobile phones, email accounts, or personal bank accounts; it is a simple, basic means of identity authentication. These … Read more
This “password” is not that “password”; key password knowledge you should know. As of July 1, the newly revised “Commercial Password Management Regulations” have officially come into effect. With the acceleration of the digitalization process, commercial passwords are now applied in all aspects of our lives, providing security assurance. The “password” referred to here is … Read more
Editor & Proofreading & Illustration: YXG (Editor) Introduction So far, there have been three industrial revolutions in human history. The first industrial revolution began with the invention of the steam engine. Its core was converting chemical energy (coal) into mechanical energy (steam engine), allowing people to no longer rely solely on animal power, water power, … Read more
This article is an excellent piece from the Kuanxue Forum. Author ID on Kuanxue Forum: Awei IntroductionTo engage with cryptography before analyzing ransomware, some algorithms are indeed too complex, and my brother finds it quite challenging, so I won’t embarrass myself. There may also be unnoticed errors, and I hope everyone can point them out … Read more
Abstract: With the continuous development of the internet and the increasing demand for security, encryption technology has become the preferred choice for ensuring traffic security. However, it has also led to a surge in encrypted malicious traffic. In the face of a complex and ever-changing network environment, the ability to quickly identify malicious traffic without … Read more
Click the blue text above Follow us! Microcontrollers (MCUs) in embedded systems are like the air traffic control systems of a busy airport. With modern MCU product lines, designers can add new features without increasing costs or reduce costs while maintaining existing feature sets, all while developing scalable software that can be reused in future … Read more
AESNI is an SIMD instruction set developed by Intel for the x64 architecture, specifically designed to provide hardware acceleration for the AES encryption algorithm. Anyone who has some understanding of SIMD is generally aware of the existence of AESNI. However, due to the asymmetric structure of AES itself and the special design of AESNI, there … Read more
In the field of computing, program packing refers to executing a “pack” program before the original program runs, and then handing the program back to the original program. The benefit of this approach is that the true entry point (OEP) of the executable program cannot be easily found through conventional cracking methods, effectively preventing the … Read more
