Abstract: Disclosed herein are techniques for generating and signing line-of-code behavior and relation models. Techniques include 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 at least one of: the line-of-code behavior and relation model or 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.

Abstract: Disclosed herein are techniques for using a line-of-code behavior and relation model to determine software functionality changes. Techniques include identifying a first portion of executable code and a second portion of executable code; accessing a first line-of-code behavior and relation model representing execution of functions of the first portion of executable code; constructing, based on the second portion of executable code, a second line-of-code behavior and relation model representing execution of functions of the second portion of executable code; performing a functional differential comparison of the first line-of-code behavior and relation model to the second line-of-code behavior and relation model; determining, based on the functional differential comparison, a status of functional equivalence between the first portion of executable code and the code portion of executable code; and generating, based on the determined difference, a report identifying the status of functional equivalence.

Abstract: Disclosed embodiments relate to opportunistically updating Electronic Control Unit (ECU) software in a vehicle. Operations may include receiving, at a controller in a vehicle, a wireless transmission indicating a need to update software running on at least one ECU in the vehicle; monitoring an operational status of the vehicle to determine whether the vehicle is in a first mode of operation in which an ECU software update is prohibited; delaying the ECU software update when the operational status is prohibited; continuing to monitor the operational status of the vehicle to determine whether the vehicle is in a second mode of operation in which the ECU software update is permitted; and enabling updating of the at least one ECU with the delayed ECU software update when it is determined that the vehicle is in the second mode of operations.

Abstract: Disclosed herein are techniques for analyzing software delta changes based on functional line-of-code behavior and relation models. Techniques include identifying a prompt to change a first version of code on a controller to a second version of code; constructing, based on the identified prompt, a line-of-code behavior and relation model representing execution of functions of the controller based on the second version of code; performing a signature operation on the generated line-of-code behavior and relation model to produce a signature value; and sending the signature value to the controller; wherein the controller is configured to compare the signature value to a computed signature value that the controller is configured to compute based on the second version of code and determine, based on the comparison, whether to validate the second version of code.
