Abstract
A cryptographic hardware security module (HSM) includes a memory storage device and an immutable hardware unit in signal communication with the memory storage device. The memory storage device is configured to store firmware. The immutable hardware unit is configured to perform a hash operation on targeted firmware stored in the memory storage device to determine an authenticity of the targeted firmware based at least in part on results of the hash operation.
