Serverless Safety Functions for Hybrid Cloud Vehicle Resource Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connected vehicles face security risks when communicating with non-trusted entities, as existing safety mechanisms struggle to manage interactions without exposing vulnerabilities, particularly in hybrid cloud environments.
Innovation Solution
Implementing a processing device that determines safety levels for vehicle resources based on predefined rules and exposes serverless functions corresponding to these levels, abstracting capabilities from implementations to mitigate security risks while enabling secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing safety mechanisms are used to manage interactions, then vehicle safety is maintained, but security vulnerabilities are exposed to non-trusted entities
Solution Approach 1:
The patent introduces a serverless function as an intermediary layer between vehicle resources and external entities. This function acts as a mediator that receives requests from non-trusted entities, evaluates them against safety rules, and executes only approved actions. The intermediary prevents direct exposure of vulnerable resources while maintaining safety through rule-based filtering and abstraction.
2Ease of operation
If serverless functions are exposed to non-trusted entities, then communication accessibility is improved, but security risks increase
Solution Approach 1:
The patent applies local quality by implementing different levels of access control for different entities. Trusted entities receive full access to serverless functions, while non-trusted entities receive limited access through abstracted interfaces. The safety rules enforce local quality control by evaluating each request based on the entity's trust level and the specific resource being accessed, allowing secure communication while maintaining accessibility.
3Reliability
If safety rules are strictly enforced, then functional safety is improved, but device complexity increases
Solution Approach 1:
The serverless function implements self-service by autonomously evaluating incoming requests against predefined safety rules and executing decisions without requiring external safety management infrastructure. The function automatically abstracts vehicle resources, enforces access control, and manages security protocols, reducing the complexity burden on the overall system while maintaining strict functional safety through automated rule-based decision-making.
Data Source
AI summary
Aspects of the present disclosure relate to fleetwide serverless functional safety protection for hybrid cloud interoperability. More specifically, a processing device receives, from a requesting entity, a message comprising an indication of a resource of a vehicle and an indication of the requesting entity. The processing device determines, based on the message and a set of safety rules for a set of resources of the vehicle, a safety level of the resource. The processing device exposes, to the requesting entity, a serverless function corresponding to the resource of the vehicle from amongst a plurality of serverless functions based on the safety level.
