Description: DES (Data Encryption Standard) algorithm. in 1977 the United States government's official permission, is a key 56 to 64 data encryption methods. IDEA is the International Data Encryption Algorith m initials yes in 1990 by the Swiss Federal Institute of Technology Xuejia Lai X. J. Massey, and the recommendations of the standard operator France called the PES (Proposed Encryption Standard). Lai and Massey in 1992 by improving strengthened against differential analysis of the capacity it renamed IDEA is the size of the 64 bit encryption of the data block encryption algorithm key to a length of 128 based on "different algebra Groups of mixed operation "design algorithm with hardware and software and is easy to achieve than in DES soon have more. Since the inception of IDEA has go
