The concept of functional safety has attracted more and more attention on the automotive embedded systems. The automotive open system software architecture standard AUTOSAR is the current international popular standard, it firstly proposes a End-to-End (E2E) security communication mechanism for functional security in the AUTOSAR4.1. In order to ensure the safety of communication between components of the vehicle, the E2E security communication mechanism under the framework of AUTOSAR is studied.By using E2E Profile 2 methods to realize the secure communication of E2E to solve the problem of how to ensure the secure communication between ECU or different SWC inside ECU.By using the E2E Protection Wrapper communication mode of the ECU nuclear communication and the COM Callout E2E mode of the ECU core communication, AUTOSAR architecture is built based on this communication mechanism.By testing the communication, the proposed method can effectively detect the repeated transmission errors, CRC checksum errors and send sequence errors .
