Source: Semiconductor Industry Observation In the past year, the soaring prices and promising prospects of Nor Flash have reignited confidence in encoded storage devices. Many manufacturers, including Gigadevice and Winbond, have made significant profits from this trend. While some may view this somewhat outdated product as lacking in technical content, Nor Flash faces various challenges … Read more
Source: Semi Connect Author: Belle Flash Memory, also known as Flash, is a type of non-volatile memory that represents data using the threshold levels of storage cells. The main technology used in Flash memory cells is the Floating Gate field-effect transistor (see Figure 5-80). The charge on the floating gate determines the threshold of the … Read more

The afternoon course was taught by Professor Xie Xiang, titled “Theory and Construction of Fully Homomorphic Encryption.” Professor Xie is a researcher at Shanghai Qi-Zhi Institute, primarily engaged in the research and implementation of efficient and secure … Read more
This article is an excerpt from a book produced by Zhihu: “Cats, Einstein, and Cryptography: Quantum Communication That I Can Understand” From Julius Caesar to Sherlock Holmes from Nazi leader Hitler to the father of AI, Turing… How did the ultimate code in the field of communication come into being? All of this must start … Read more
A few days ago, the news of Google cracking the SHA-1 algorithm flooded my social media feed. In fact, the term “crack” is not entirely accurate, it should be that they published an example of breaking the SHA-1 algorithm. Regarding this news, I saw two different comments: A: Wow, that’s amazing! They actually cracked an … Read more
Generate an information digest from plaintext encoding to prevent tampering. For example, MD5 uses a hash algorithm, which outputs a 128-bit string regardless of the input length. The digest algorithm does not require a secret key; both the client and server can use the same digest algorithm to obtain consistent ciphertext for the same plaintext. … Read more
Photographer: Product Manager This Skewered Food Shop Has Finally Opened When reading various encryption articles, you often see that the authors use numbers as examples for encryption. However, in real life, we communicate in Chinese. So how can we encrypt Chinese text? In the article “Don’t Worry, No One Can Snooze Our Chat Messages”, we … Read more
Authors：Zhao Yiqiang，Song Kaiyue，He Jiajie，Ma Haocheng Abstract：In response to current hardware security threats such as integrated circuit (IC) counterfeiting and intellectual property (IP) theft, we propose an enhanced logic encryption algorithm based on secure authorization keys. This algorithm locates the insertion point of the “key gate” through a rare node analysis method, using the fully correlated … Read more
Reliable and Efficient: The Block Cipher Written by | Teacher Kang In the previous five issues, we discussed the intrinsic characteristics and structures of cryptography, as well as the relationship between cryptography and security. Starting from this issue, we enter the second part of this series – the
