Autonomous Vehicle Remote Control With Cryptographic Emergency Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack the capability to securely recognize and respond to emergency vehicles, as they cannot process external stimuli like human operators, leading to security issues such as rogue vehicles impersonating emergency vehicles with minimal effort.
Innovation Solution
Implementing a cryptographically secure authentication system using DICE-RIoT to verify messages from emergency vehicles, ensuring secure communication through a tamper-proof blockchain data structure, and executing commands securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image recognition and audio recognition are used to identify emergency vehicles, then autonomous vehicles can detect emergency signals, but security issues arise where rogue vehicles can impersonate emergency vehicles
Solution Approach 1:
The patent introduces cryptographic certificates and digital signatures as an intermediary mechanism between emergency vehicles and autonomous vehicles. Instead of relying solely on perceptual recognition (lights, sirens), the system uses a trusted cryptographic intermediary to verify identity, preventing rogue vehicles from impersonating emergency vehicles while maintaining reliable detection capabilities
Solution Approach 2:
The patent replaces the mechanical/perceptual recognition system (image recognition, audio recognition of sirens and lights) with a cryptographic verification system. Digital signatures and certificate validation substitute for visual and auditory identification methods, eliminating the security vulnerability of impersonation while preserving the ability to identify genuine emergency vehicles
2Reliability
If cryptographic authentication and blockchain logging are implemented, then message security and authenticity are ensured, but system complexity increases
Solution Approach 1:
The patent implements a universal cryptographic authentication framework where certificates and digital signatures serve multiple functions: verifying emergency vehicle identity, authenticating control messages, ensuring message integrity, and providing non-repudiation. This multi-functional approach consolidates security requirements into a single coherent system, managing complexity through functional integration rather than separate mechanisms
Solution Approach 2:
The patent performs preliminary cryptographic setup by issuing certificates to vehicles before they operate in the autonomous vehicle system. The authentication infrastructure is established in advance, with certificates pre-configured in vehicles, so that during actual emergency operations, the system can quickly verify identities without complex real-time authentication negotiations, reducing operational complexity

AI summary
Disclosed are techniques for remotely controlling autonomous vehicles. In one embodiment, a method is disclosed comprising receiving a message from a first autonomous vehicle, the message including a signed body portion and a triple including components selected from the group consisting of a public identifier of the first autonomous vehicle, a public key of the first autonomous vehicle, and a certificate of the first autonomous vehicle; authenticating the message by verifying the certificate of the first autonomous vehicle; logging the message into a blockchain storage structure, the blockchain storage structure storing a plurality of blocks, each blocking including the signed body portion; and executing one or more orders included within the signed body portion.
