original: A large proportion of block ciphers use the scheme, including the Data Encryption Standard (DES).
simplifications: A lot of block ciphers use schemes like the Data Encryption Standard. Many block ciphers use this scheme, including the Data Encryption Standard (DES). A part of block ciphers use the process, including Data Encryption Standard. Many block ciphers use the scheme, including the Data Encryption Standard (DES). Many block ciphers use the scheme, including the Data Encryption Standard (DES). Many block ciphers like the Data Encryption Standard use the scheme. A large percentage of block ciphers use the scheme. One example is the Data Encryption Standard. A large amount of the block ciphers use the plan, as well as the Data Encryption Standard (DES). A large percentage of block ciphers  use this method. The Data Encryption Standard also uses this method. The scheme is used by a large proportion of block ciphers, including the Data Encryption Standard (DES).
