| Abstract: | IDEA algorithm is based on the DES algorithm,it is a block cipher algorithm using 128-bit key to encrypt data with a 64-bit grouping as the unit.On the base of thorough analysis and research on the main idea of IDEA algorithm,the implementation principle and process of the IDEA algorithm are discussed,particularly,the key expansion and encryption process are discribed in details,and the IDEA symmetric encryption algorithm is designed and implemented in the C# environment. |
