System Infrastructure - AES
The Zywpeit system makes use of AES encryption to help keep data secure, AES is short for Advanced Encryption Standard and is also known by its
original name Rijndael. It is essentially a specification for the encryption of electronic data established by the U.S. National Institute of
Standards and Technology (NIST). AES has been adopted by the U.S. government and is now used worldwide, it supersedes and replaces the Data Encryption
Standard (DES) which was published in 1977. The algorithm described by AES is a symmetric-key algorithm, meaning the same key is used for both
encrypting and decrypting the data.
In the United States, AES was announced by the NIST as the preferred standard on November 26, 2001. This announcement followed a five-year
standardization process in which fifteen competing designs were presented and evaluated, before the Rijndael cipher was selected as the most suitable.
AES became effective as a federal government standard on May 26, 2002, after approval by the Secretary of Commerce and is included in the ISO/IEC 18033-3
standard. AES is the first (and only) publicly accessible cipher approved by the National Security Agency (NSA) for top secret information when used in an
NSA approved cryptographic module.
How Secure Is AES? - With current computer hardware it would take billions of years to brute force (guess the encryption key).
Also, the algorithm authors calculate the best attack using their technique on AES with a 128 bit key requires the attacker to store 288
bits of data. That works out to about 38 trillion terabytes of data, which is more than all the data stored on all the computers
on the planet as of 2016. As such, there are no practical implications on AES security.
