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
1Adaptability or versatility
If a rudimentary system using image recognition and audio recognition is employed to identify emergency vehicles, then autonomous vehicles can respond to emergency signals, but security issues arise where rogue vehicles can impersonate emergency vehicles with minimal effort
Solution Approach 1:
The patent introduces cryptographic certificates and digital signatures as an intermediary mechanism between emergency vehicles and autonomous vehicles. Instead of directly trusting visual or audio signals, the system uses cryptographic verification as a mediator to authenticate the identity of emergency vehicles, preventing rogue vehicles from impersonating them.
Solution Approach 2:
The patent replaces the mechanical/optical system of image and audio recognition with a cryptographic system based on digital signatures and certificates. This substitution transforms the authentication mechanism from sensory-based recognition to mathematically secure verification, eliminating the security vulnerabilities of the previous approach.
2Reliability
If cryptographic authentication systems are implemented to secure communications, then security against impersonation is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-distributing cryptographic certificates to authorized emergency vehicles before they need to communicate. This advance preparation allows the system to maintain high security without adding complexity during critical moments, as the authentication infrastructure is already in place and configured.
Solution Approach 2:
The patent creates a universal cryptographic authentication system that can be applied across all autonomous and emergency vehicles in the fleet. This multi-functional approach allows a single cryptographic infrastructure to serve multiple purposes: authentication, authorization, and secure communication, reducing overall system complexity compared to implementing separate solutions for each function.
