Advanced Encryption Standard (AES) is the currently defined standard for encryption of digital data. Since 2005, sensitive and confidential data is encrypted via a special algorithm which so far has not been able to be attacked. This method fulfils the highest level of confidentiality, so that even governmental documents can be secured with this method.
