Intrinsic ID Zign® RNG – NIST-Certified Random Number Generator, software-only implementation
Zign RNG is an embedded software implementation that leverages existing SRAM as a PUF, so it is the only hardware entropy source that does not need to be loaded at silicon fabrication. Zign RNG can be installed later in the supply chain, and even retrofitted on already-deployed devices. This enables a never-before-possible “brownfield” deployment of a cryptographically secure, NIST-certified RNG.
