A Comparative Study of JASO TP15002-Based Security Risk Assessment Methods for Connected Vehicle System Design

: Assumption List.


Type	Assumption	Overview

Objective	A.No_Objective_to_CGW	It is assumed that there is no advance security objective for CGW, in order to identify all key threats at the initial stage of security design.

Physical	A.Physical_access_by_Outsider	The “Chassis” module, the “Body” module, and the “ADAS” module are connected to other modules only via an in-car bus, so they are not attacked directly through any physical interfaces.
	A.Attack_to_Sensor_Receptor	The “ADAS” module also has radar and sensors as its interface. These receptors from which this module gets the location information are treated as physical interfaces without transmission function.

Human Factor	A.Automatic_drive	The transfer of the driver’s authority is not assumed regarding the use of the functions for automatic drive.

Communication	A.GPA	The communication to Satellite is a one-way (Satellite -> Vehicle), the same as the Sensor.
