original: The AES ciphers have been analyzed extensively and are now used worldwide, as was the case with its predecessor, the Data Encryption Standard (DES).
simplifications: The AES ciphers have been looked at extensively and are now used worldwide. AES ciphers have been examined greatly and are now used worldwide, just like the Data Encryption Standard was. The AES ciphers have been analyzed a lot and are now used worldwide. Similar thing happened to the Data Encryption Standard. The AES ciphers have been analyzed extensively. They are used worldwide now. It was the same with the Data Encryption Standard (DES). The AES ciphers have been heavily analyzed. They are now used worldwide, just like their predecessor, the Data Encryption Standard (DES). The AES ciphers have been analyzed a lot.
