Access Security for AUTOSAR ECUs
The growth in the amount of safety-related information and personal data in the automobile is making protection against intentional data manipulation and data theft increasingly more important. Security mechanisms are being used to protect the integrity, authenticity and confidentiality of information. In this area, Vector can offer you components specified in AUTOSAR 4.3.
Overview of Advantages of MICROSAR Security
- Standard-conformant implementation of security functions from a single source
- Established cryptographic algorithms
- Protection against unauthorized modification of critical data
- Authentication of communication end points
- Protection against unauthorized reading of data
Secure OnBoard Communication (SecOC)
This module is used for secure communication between ECUs. It prevents a 3rd party from manipulating data in transit,
replaying recorded data and claiming to be the correct communication partner. This prevents manipulative interventions. The
SecOC interacts with the PDU router, and can be controlled by the application.
Cryptographic Service Manager (CSM)
The Cryptographic Service Manager provides access to cryptographic services.
Crypto Interface (CRYIF)
The Crypto Interface module provides a single interface to handle different crypto solutions.
The module CRYPTO (SW) provides the actual implementations for the cryptographic algorithms and functions which are
provided via the CSM.
The Crypto (HW) module acts as a driver for accessing the security algorithms and functions provided by a hardware trust
Ethernet Firewall (vETHFW)
The Ethernet firewall vETHFW provides an implementation of a firewall for Ethernet communication. Its main task is to
block unwanted traffic which is received or transmitted in order to increase the security of the entire network.
