Abstract
System and techniques to generate a cryptographic key specific to a type of hardware are described herein. Software distribution and execution can use cryptographic keys tailored to specific hardware. A secret is generated from a hardware public key. The secret is used to create software public and private keys. The secret is used to protect the data and the public key is distributed with the software for use on a class of hardware to which the hardware private key is applicable. The hardware then uses the software public key and a local copy of the hardware private key to find the secret and decrypt the software to run the software locally.
