tandard. The NIST (National Institute of
Standards and Technology) has been developing the AES encryption
standard jointly with industrial companies for years. This
symmetrical encryption is designed to replace the previous DES
standard. The AES standard specifies three different key sizes with
128, 192 and 256 bits.
In 1997, the NIST launched the AES initiative and announced its
conditions for the algorithm. Of the encryption algorithms proposed,
the NIST short-listed five; the algorithms MARS, RC6, Rijndael,
Serpent and Twofish. In October 2000, the encryption algorithm
chosen was Rijndael.
APN (Access Point
Name)
Trans-network connections, e.g. from a GPRS network to the Internet,
are created in the GPRS network via so-called APNs.

APN
(private)
An end device that wants to establish a connection via the GPRS
network specifies an APN to indicate which network it wants to be
connected to: the Internet or a private company network that is
connected via a dedicated line.
The APN designates the transfer point to the other network. It is
communicated to the user by the network operator.
