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.
