Abstract
A security data processing device comprising a processor and memory, the processor configured to: receive a script comprising at least one instruction set for provisioning a type of programmable device, the instruction set(s) defining one or more cryptographic operations, each of the cryptographic operations referring to a parameter; store the script in memory; verify a signature associated with the script using an authorization key retrieved from memory; receive a programming request from a programming module of a programming machine in communication with said processor, said programming request requesting the programming of a programmable device and identifying an instruction set of the instruction set(s) in said script; for each cryptographic operation in the identified instruction set, determine a value for the parameter and perform the cryptographic operation using the value; and in response to performing each cryptographic operation, output programming information to the programming module for programming the programmable device.
