Did Rijndael cipher win a competition call by NIST to become the AES cryptosystem?
The Rijndael cipher did win the competition held by the National Institute of Standards and Technology (NIST) in 2000 to become the Advanced Encryption Standard (AES) cryptosystem. This competition was organized by NIST to select a new symmetric key encryption algorithm that would replace the aging Data Encryption Standard (DES) as the standard for securing
Public-key cryptography, also known as asymmetric cryptography, is a fundamental concept in the field of cybersecurity that emerged due to the issue of key distribution in private-key cryptography (symmetric cryptography). While the key distribution is indeed a significant problem in classical symmetric cryptography, public-key cryptography offered a way to resolve this problem, but additionally introduced
What are some predefined categories for object recognition in Google Vision API?
Google Vision API 是 Google Cloud 机器学习功能的一部分,提供高级图像理解功能,包括对象识别。在对象识别的背景下,API 使用一组预定义的类别来准确识别图像中的对象。这些预定义的类别可作为 API 机器学习模型进行分类的参考点
