CLP-38f: KASUMI 3G Cipher Core

The CLP-38f 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-38f.

Key Features:

  • KAUSMI cipher for 3GPP
    • Supports both the Confidentiality (f8) and Integrity (f9) modes
  • Maximum clock frequency: 175 MHz in a XC5VLX50-3
    • 656 Mbps throughput
  • In-line or flow-through architectures available
    • Ingress and egress FIFO depth configurable at build time in flow-through engine
  • Hardware key expansion logic
  • Available under terms of the Xilinx SignOnce IP License
  • Key size - 128 bits

Applications:

  • 3GPP - UMTS and LTE
