CLP-41: SNOW 3G Cipher Core

The CLP-41 core implements the SNOW 3G stream cipher that forms the heart of the 3GPP confidentiality algorithm UEA2 and the 3GPP integrity algorithm UIA2. The standard is governed by ETSI document - SNOW 3G Algorithm Specification Version 1.1. The CLP-41 implements a flow-through or in-line version of the core although the core can also be provided as a look-aside engine. The base cipher can be supplemented by wrapper to offer both the confidentiality and authentication algorithms.

Key Features:

• SNOW 3G cipher for 3GPP
• Maximum clock frequency: 408 MHz in 90 nm
• 960 Mbps @ 100 MHz for 64 byte messages (UEA2)
• 2.5 Gbps @ 100 MHz for 512 byte messages (UEA2)
• Flow-through architecture
• Ingress and egress FIFO depth configurable at build time
• Key size - 128 bits
• 35K ASIC gates (supports both UEA2 and UIA2)

Applications:

• 3GPP
