In today’s circuit design, the vast majority of scenarios involve mixed-signal circuit designs that integrate both digital and analog components, and the intermediate connection channels in mixed circuits inevitably rely on ADC and DAC. For example, the joystick inside our daily remote controls operates on the principle of a sliding potentiometer. Some higher-end designs use … Read more
Abstract: A SAR imaging processing scheme based on multicore DSP interconnection architecture is proposed. First, a real-time imaging algorithm based on azimuth sub-block interpolation is introduced. Second, the processing performance of the TI multicore DSP TMS320C6678 is studied, and a typical RapidIO interconnection architecture is introduced, followed by the proposal of a SAR imaging processing … Read more
Hello everyone, I am Xiaozao. The first official 5G standard is about to be released, and I believe everyone is eagerly looking forward to it. Previously, I introduced to everyone that back in December last year, we actually released a “half” 5G standard. That’s right, at that time it was the “Non-Standalone (NSA)” 5G standard. … Read more
Python Encryption Algorithm Practice: Protect Your Data Security Hello everyone, today we are going to talk about encryption algorithms in Python. In this data-driven era, protecting sensitive information has become increasingly important. Whether it’s protecting user passwords or encrypting important files, mastering some basic encryption techniques is very useful. So, let’s explore the secrets of … Read more
History Before 1976, the encryption world mainly used Symmetric-key algorithms. Symmetric encryption has a troublesome problem: when parties A and B communicate, A must inform B of the encryption rules; otherwise, decryption is impossible. Is it possible to ensure the security of key storage and transmission? In 1976, two American computer scientists, Whitfield Diffie and … Read more
Recently, Jason invited Mei from the Mathematics Department of Fudan University to give five hardcore math classes for friends interested in Web3. Starting from natural numbers, he explained the details of RSA asymmetric encryption. Let me review and try to explain this rather complex topic. (Math warning ahead, but I promise to limit it to … Read more
1. Overview of Cryptographic Algorithms Cryptographic algorithms play a crucial role in today’s digital age. With the rapid transmission and storage of information, protecting data security and privacy has become a top priority. Cryptographic algorithms are mainly divided into three categories: symmetric encryption, asymmetric encryption, and hashing algorithms. Symmetric encryption algorithms are an early and … Read more
Source:http://dwz.date/afUd 1. Basic Concepts of Encryption “Encryption” is a technology that restricts access to data transmitted over the network. The original data (also known as plaintext) is encoded into ciphertext by encryption devices (hardware or software) and keys. The process of restoring ciphertext back to the original plaintext is called decryption, which is the reverse … Read more
Background Recently, some security requirements were rectified in the project. Encryption is one of the commonly used means during the process. Here is a brief summary, hoping to help everyone. Usage Scenarios Encryption is a process that transforms raw information (plaintext) into a form (ciphertext) that is difficult to understand directly. The main purpose is … Read more
This article is reprinted from the SegmentFault community Community Column: Love Frontend Author: linshuai In today’s world, where information security is becoming increasingly important, various encryption methods in frontend development have also become more critical. Typically, in interactions with servers, to ensure the security of data transmission and prevent data tampering, in addition to the … Read more
