MicroPeckerX Message Authentication Plugin​

MicroPeckerX CAN FD Analyzer​

Feature Overview​

This product provides the following features.

Feature	Overview
Message authentication settings	Detailed message authentication settings (MAC/FV, etc.) by channel and CAN ID for CAN/CAN FD communication. Supports JASPAR specification and custom profiles.
Monitoring and log display	Real-time display and recording of authenticated message TX/RX status, verification results (OK/NG), and parameters (MAC, FV, payload, etc.).
Security settings management	Security settings can be saved to and loaded from files for easier multi-project and complex setting management.
Callout DLL integration	User-defined authentication algorithms and parameter generation logic (MAC key, FV generation, etc.) can be integrated via external DLL.
JASPAR support	Supports settings and verification compliant with JASPAR message authentication flow and counter structure.
Error message display	Displays detailed error messages and countermeasures for invalid settings and authentication errors.
Bulk management/list display	CAN ID list and authentication parameters can be managed and reviewed in bulk on the GUI.

*1: Verify these requirements in advance using System Checker.
*2: On PCs with power-saving functions, configure settings so sleep, HDD stop, and CPU clock throttling do not occur while using this product.
*3: Virtual environments are not supported.
*4: Includes Intel Core 4th generation or later.
*5: Ensure sufficient free disk space for long-term monitoring.
*6: When using an external USB hub, use a self-powered hub and supply external power before connection. Bus-powered hubs may not work correctly or may be unstable.

Check with System Checker​

Before using the MicroPeckerX message authentication plugin, be sure to verify that your CPU is supported using the System Checker tool below. If requirements are not met, This computer doesn't meet system requirement is shown in Security Window, and message authentication cannot be used.

Terminology​

Definitions of terms used in this manual are listed below.

Term	Description
CAN	Abbreviation of Controller Area Network. A communication protocol developed for in-vehicle networks and standardized by ISO 11898.
CAN FD	Abbreviation of CAN with Flexible Data-rate. An extended CAN protocol for higher speed and larger payload, standardized as ISO 11898-1:2015.
MicroPeckerX	Generic name of hardware systems with in-vehicle communication interfaces, used with applications for data acquisition and analysis.
Arbitration	Identifier (ID) field at the beginning of a CAN frame. When multiple nodes transmit simultaneously, priority is determined by ID.
Payload	Data field in a CAN frame containing actual data (signal values), up to 8 bytes (CAN) or 64 bytes (CAN FD).
Ch	Abbreviation of channel. Physical or logical communication path on CAN bus. MicroPeckerX supports multiple channels and independent TX/RX per channel.
GW	Abbreviation of gateway. Hardware/software that relays data between networks with different communication protocols.
Monitoring	Real-time display of data acquired from the CAN bus on the GUI application.
Logging	Automatic saving of data acquired from CAN bus to a PC folder as text file (.csv).
Message authentication	Mechanism to verify both sender authenticity (anti-spoofing) and message integrity (anti-tampering).
MAC	Information used for message authentication to verify sender and tampering; abbreviation of Message Authentication Code.
FV	Counter value used so MAC input changes continuously; abbreviation of Freshness Value.
CMAC/AES-128	One of the cryptographic algorithms used for message authentication. CMAC (Cipher-based Message Authentication Code) generates MAC using AES-128 and allows fast secure verification.
Security profile	A set of configuration values/specifications defined by AUTOSAR SecOC (Secure Onboard Communication) to implement security functions such as message authentication. Defines authentication method, MAC generation, FV management, and data layout for standardized secure ECU communication.
Prefix/Postfix	Data elements prepended/appended during MAC generation. Content and length vary by security strength/specification.
Element	Fine-grained data element composing Prefix/Postfix. Bit position, length, and initial value can be configured per element.
JASPAR	General incorporated association established to improve efficiency and reliability through standardization/common use of automotive software and network architecture; abbreviation of Japan Automotive Software Platform and Architecture.
