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.
Cross-network connections, e.g. from the GPRS network into the
Internet are established in the GPRS network via so-called APNs.
G P R S
terminal
A terminal wishing to establish a connection via the GPRS network
specifies the network with which it wishes to be connected via the
APN:
•
the Internet,
•
a private corporate network connected via a dedicated line.
The APN denotes the point of access to the other network.
