The IntelliProp IPC-BL204-ZM is an AES-CTR Counter Mode Encryption Core supporting 128 or 256 bit encryption. The IPC-BL204-ZM provides encryption/decryption based on a design principle known as substitution-permutation network (SP-network). An SP-network takes a block of the plaintext (clear...
CTR(计数器模式,Counter Mode)是对称加密算法的一种模式,广泛应用于数据加密领域。它将块密码转化为流密码,通过将明文与一个以计数器为基础的密钥流进行异或运算,达到加密的目的。本文将介绍CTR加密的基本原理,并提供一个Python代码示例,帮助读者理解其具体实现。 1. 什么是CTR加密? CTR模式的工作原理包括以下几步:...
In this paper, we revisited the previous Fast AES-CTR mode Encryption (FACE) method for high-end processors and tailored the method to the microcontrollers, namely FACE-LIGHT. We targeted the 32-bit counter mode of operation for AES in constant timing. This optimized technique pre-computes the...

高级加密标准(英语:Advanced Encryption Standard,缩写:AES),在密码学中又称 Rijndael 加密法,是美国联邦政府采用的一种区块加密标准。 该标准是用来替代原先的 DES,现已经被多方分析且广为全世界所使用,成为对称密钥加密中最流行的算法之一。 AES 采用对称分组密码体制,加密数据块分组长度必须为 128 比特,密钥长度可...
