Report ID: TR-2023-GM-5B Subject: Security Analysis of the GM 5-Bit Seed/Key Security Access Mechanism Classification: Automotive Security / Reverse Engineering 1. Executive Summary This report details the technical analysis of the proprietary "5-Bit" Seed/Key algorithm utilized in legacy General Motors (GM) Electronic Control Units (ECUs). This algorithm is employed to restrict access to specific diagnostic services (via Unified Diagnostic Services - UDS or KWP2000) over the Controller Area Network (CAN) bus.
