The CLP-38 core implements the KASUMI cipher. The KASUMI cipher is specified in the SAGE/ETSI document "Specification of the 3GPP TS 35.202 V7.0.0 (2007-06)". The algorithm implements a block cipher that produces a 64-bit output from a 64-bit input using a 128-bit key. The standard requires both a confidentiality algorithm known as f8 and an integrity algorithm known as f9 - both can be implemented in the CLP-38.
• KASUMI cipher for 3GPP
o Supports both the confidentiality (f8) and Integrity (f9) modes
o Supports GSM A5/3, ECSD A5/3 and GSM GEA3 keystream generation
• Maximum clock frequency: 200 MHz in 0.13 micron
o 800 Mbps throughput
• Flow-through architecture
o Ingress and egress FIFO depth configurable at build time
