Data encryption algorithm (Data Encryption Algorithm, DEA) of the Data Encryption Standard (Data Encryption Standard, DES) is a standardized description of it from IBM s research work and, in 1997, formally adopted by the U.S. government. It is probably the most widely used secret key system, especially in protecting the safety of financial data, the initial development of DES is embedded in hardware. Usually, automated teller machines (Automated Teller Machine, ATM) are the use of DES. Document is described in VHDL code DES
