Generating and signing a line-of-code behavior and relation model

A non-transitory computer readable medium including instructions that, when executed by at least one processor, cause the at least one processor to perform operations for generating and signing a line-of-code behavior and relation model, comprising:

• identifying executable code for a controller;
• performing a functional analysis of the executable code to determine a plurality of functions associated with the executable code and a plurality of relationships between the plurality of functions;
• generating, based on the determined plurality of functions and plurality of relationships, a line-of-code behavior and relation model for the executable code;
• performing a signature operation on the generated line-of-code behavior and relation model to produce a unique signature value associated with the line-of-code behavior and relation model and a functional block of the line-of-code behavior and relation model;
• and
• linking the unique signature value to the line-of-code behavior and relation model.
