Overview
The 3rd Generation Partnership Project (3GPP) is a collaborative effort between several global telecommunications
standards bodies to develop and maintain technical specifications for 3rd Generation mobile systems and beyond.
The data confidentiality and integrity algorithms currently defined to provide data security within the 3GPP specifications
are based on three underlying encryption algorithms; KASUMI, SNOW3G, and the Advanced Encryption Standard (AES).
Helion can provide highly efficient IP cores for these algorithms in a range of technologies as detailed below.
KASUMI
KASUMI is a 64-bit block cipher which uses a 128-bit key. It forms the basis of the
confidentiality (f8 or UEA1) and integrity (f9 or UIA1) algorithms which provide data security
for signalling and user data within the GSM, GPRS, EDGE and UMTS standards.
Helion provides KASUMI-based IP cores to perform the f8 (UEA1) and f9 (UIA1) algorithms. The f8 core can also
support the GSM A5/3 and GPRS GEA3 encryption algorithms. They are available in versions for use in ASIC, as well as
Altera and Xilinx FPGA. In common with all Helion IP cores they have been designed with each technology
firmly in mind to yield the most efficient results. For more detailed information on these cores, please
download the appropriate datasheet by selecting your chosen target technology from the table below:
SNOW3G
SNOW3G is a stream cipher which uses a 128-bit Key and IV. It provides the basis for the
UEA2 confidentiaility and UIA2 integrity algorithms introduced in 3GPP Release 7 to provide
data security for signalling and user data within the UMTS standard. Subsequently, in 3GPP
Release 8, the 128-EEA1 confidentiality and 128-EIA1 integrity algorithms (which are identical
to UEA2 and UIA2 respectively) were introduced for use within the LTE standard.
Helion provide SNOW3G IP cores which are available in versions for use in Altera and Xilinx FPGA.
In common with all Helion IP cores they have been designed with each technology
firmly in mind to yield the most efficient results. For more detailed information
on these cores, please download the appropriate datasheet by selecting your
chosen target technology from the table below:
AES
3GPP Release 8 introduced confidentiality and integrity algorithms based on the Advanced Encryption Standard (AES)
128-bit block cipher with 128-bit key size to provide data security within LTE networks. The 128-EEA2 confidentiality algorithm uses AES
in Counter mode (specified in NIST SP800-38A) and the 128-EIA2 integrity algorithm uses AES in Cipher-based MAC
(CMAC) mode (specified in NIST SP800-38B). Helion has a range of product proven AES IP cores which can support
these cipher modes for a range of data throughputs, please see our AES pages or contact Helion for more details.
