Many cryptographic operations require a source of random numbers primarily in the creation of cipher keys. Elliptic’s silicon proven CLP-27: Compact True Random Generator 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.
The Compact True Random Number Generator also integrates seamlessly in ARM-based SOCs and enables designers to efficiently balance: power, performance, and silicon area.
