ARINC 829

This specification focuses on various aspects of connections between portable devices and onboard network infrastructures. First, it addresses the wireless technology used for these connections, including standards like IEEE 802.11, and other applicable protocols. Understanding the specific wireless technology employed is crucial for ensuring compatibility and optimizing performance. Device authentication methods are also a key consideration within this scope. Different authentication mechanisms, such as Pre-Shared Key, RADIUS authentication, and Service Set Identifier (SSID) policies, are examined to establish secure and authorized connections between portable devices and the onboard network. Robust authentication measures help prevent unauthorized access and maintain the integrity of the network. Certificate management is another critical aspect covered in this specification. It encompasses the management of certificates for both the AID and tablet EFB devices. Effective certificate management ensures the authenticity and integrity of the devices involved in the connection, enhancing overall security. Additionally, this specification delves into the operation of portable devices as part of a larger aircraft network. Understanding how these devices integrate into the broader network infrastructure is essential for seamless communication, data exchange, and coordination among different systems and components within the aircraft. Network protection is of utmost importance, particularly when it comes to safeguarding against unintended access by passengers. Measures to establish domain protection are examined to ensure that only authorized devices and users can access the network, preventing potential security breaches. The specification also addresses failure mode scenarios, which involve identifying and mitigating risks associated with network disruptions or device malfunctions. Preparing for and managing such failure scenarios is crucial for maintaining continuous and reliable connectivity. Network management, specifically the ability to query status, is another area covered by this specification. Having the means to monitor and assess the status of the network and connected devices allows for proactive troubleshooting and maintenance, ensuring optimal performance. Finally, the specification incorporates Wireless Risk Analysis/Assessment/Management as per the guidelines outlined in RTCA DO-326A. This ensures that comprehensive risk analysis and management practices are implemented to address potential vulnerabilities and mitigate wireless-related risks effectively.
