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
Concept of ADAS: Advanced Driving Assistance System (ADAS) utilizes various sensors installed in the vehicle (millimeter-wave radar, LiDAR, monocular and binocular cameras, and satellite navigation) to sense the surrounding environment during the vehicle’s operation, collect data, identify, detect, and track static and dynamic objects, and perform systematic calculations and analyses combined with navigation map data. … Read more
