The operation of the AES algorithm is shown inFigure 36-2. The encryption step uses a key that converts the data into an unreadable ciphertext, and then the decryption step uses the same key to convert the ciphertext back into the original data. This type of key is asymmetric...
AES是由美国国家标准与技术研究院(NIST)于2001年确定的,它取代了过时的数据加密标准(Data Encryption Standard,DES)。 以下是AES加密算法的主要特点和概述: 对称密钥算法: AES是一种对称密钥算法,意味着相同的密钥用于加密和解密数据。这就要求通信双方在通信前共享密钥,并确保其保密性。 分组密码: AES将明文数据...

Multiplication in GF(28) is trickier, however. As you'll see later in the C# implementation, the AES encryption and decryption routines need to know how to multiply by only the seven constants 0x01, 0x02, 0x03, 0x09, 0x0b, 0x0d, and 0x0e. So instead of explaining GF(28) multipli...
in November 2001 after a 5-year standardization process. The AES encryption & decryption algorithm is implemented on the FPGA. This has to have an interface with the PC. The C source for the encryption and decryption is already provided. The algorithm is implemented to work in software and ...
