Definitions[]

A cryptographic boundary is

an explicitly defined contiguous perimeter that establishes the physical bounds of a cryptographic module and contains all the hardware, software, and/or firmware components of a cryptographic module.[1]
a logical container where all the relevant security components of a control system that employ cryptography reside. It includes the processing hardware, data, and memory as well as other critical components.[2]
