CLP-27: Compact True Random Number Generator

Many cryptographic operations require a source of random numbers primarily in the creation of cipher keys. This core combines a whitening circuit with a noise source that provides automatic seeding of the random number stream and an ongoing source of entropy to the core. The core is therefore classified as a non-deterministic random bit generator using the terminology preferred by NIST. The noise source does not depend on process specific circuitry and is therefore very portable across different fabrication technologies.

Key Features:

• Area: 5K ASIC gates
• Compliant to both NIST 800-22 and FIPS 140-2
• Full SPA/DPA timing attack resistance
• High speed operation - 3 Mbps at 50 MHz core clock
• Initial seed provided from internal noise source
• Automatic re-seeding
• Test bench provided

Applications:

• WiMax applications such as 802.16
• IPSec designs in gateways and enterprise routers
• WLAN applications such as 802.11i
• Digital Rights Management
• TPM designs
• Military communications systems
