AI Technical Summary

Technical Problem

In distributed systems, particularly in modern vehicles, determining the identity of software entities across nodes running different operating systems poses a challenge for secure and efficient communication, as existing identity mechanisms are not effectively interoperable across diverse OS installations.

Method used

The implementation of a remote proxy system that utilizes operating system verification mechanisms, such as UIDs and GIDs, to securely verify and sign messages between nodes, allowing secure communication by treating messages as local and enforcing security policies across different OS installations.

Benefits of technology

This approach enables secure and efficient communication between nodes with different operating systems by using remote proxies to verify and sign messages, ensuring authorized access and preventing tampering, thus maintaining system security and efficiency.

Abstract

A method at a remote proxy on a first node, the method including receiving, at the remote proxy, a first message from a first module on the first node, the first message being directed to a second module on a second node; verifying the first message at the remote proxy utilizing operating system verification; determining, based on a manifest at the remote proxy, the second node; signing, using a private key for the first node, the first message; and sending the first message to the second node.
