Technical Blog / Methods and benefits of M2354’s protection against side-channel attacks
https://www.nuvoton.com/support/technical-support/technical-articles/TSNuvotonTechBlog-000364/
Information security relies not only on cryptography algorithms but also on the protection of the machine itself. However, when system chips are usually running, they inadvertently leak some messages on physical features. These messages will be spread outside the system chip through physical phenomena such as voltages, currents, and electromagnetic waves, and attackers can analyze these exposed messages to reverse analyze the keys in the chip. This type of attack that uses the physical information leaked from the operation of password systems to crack the system is called a side-channel attack. M2354 is developed by Nuvoton used to meet the needs of the times for MCU performance and security; it provides accelerators for the cryptography algorithm of various hardware, and multiple message protection functions including AES, ECC, RSA, HMAC, and high-quality True Random Number Generators (TRNG). It is also equipped with an exclusive Key Store to save keys, allowing it to be applied in

NuMicro® M2351 applications｜Short-range wireless communication module, 802.15.4 thread module Nuvoton Microcontroller Application Business Group Technology Manager – Robert Ling What is 802.15.4 Thread? First, let’s take a look at which are the mainstream communication standards of the Internet of Things (IoT). According to the figure above, we can see that the communication methods of IoT are divided into two major categories long-range wireless and short-range wireless; and these two major standards include many detailed standards that need to be discussed. Let’s take a look at the explanations in the next table to learn about some factors that need to be considered when these different standards are used. *1: Low-Power Wide-Area Network Range > 1km, for example, LoRA, SigFox, NB-IoT *2: Short Range < 100m, for example, ZigBee, Thread, Z-Wave or Bluetooth From the table above we can clearly understand that wireless communication needed for terminal devices with sensors to collect

NuMicro® M2351 applications｜Smart Authentication, USB FIDO Key Nuvoton Microcontroller Application Business Group Technology Manager – Robert Ling What is FIDO (Fast Identity Online)? First, let’s look at what FIDO is. Based on the literal letters, we can easily guess that it is a method related to network authentication. Indeed, since traditional information systems keep having problems with password authentication whether it is insufficient security, stolen account, difficult to remember passwords or inconvenient usage, etc., users kept complaining about it. Plus, with the emerging of the internet, more and more network connections require safer and faster network identity identification technologies; therefore, the FIDO standard began formulating in 2012 by the FIDO Alliance, which composed on several large companies such as PayPal, Nok Nok Labs, and Lenovo. Many other major companies in the information and communication industry such as Google, Alibaba, Intel and Qualcomm, even
