SoC Security Engine for Sensor Data Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld devices lack effective protection and security measures for sensitive sensor data, such as user health information and location data, which can be compromised when transmitted to backend services.
Innovation Solution
A system on chip (SoC) with an integrated sensor hub and security engine is used to collect, process, and encrypt sensor data, ensuring secure transmission by adding certificates and using encryption keys, thereby protecting sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensor data is transmitted to backend services, then applications can utilize sensor data for various features, but user sensitive information is exposed and unprotected
Solution Approach 1:
The patent introduces a security engine as an intermediary component between the sensor hub and backend services. This security engine processes sensor data through encryption and authentication mechanisms, allowing applications to access protected data while preventing unauthorized exposure. The security engine acts as a mediator that enables data utilization while mitigating the harmful effect of data exposure.
Solution Approach 2:
The patent applies preliminary action by encrypting and securing sensor data before it is transmitted to backend services or made accessible to applications. The security engine performs authentication and encryption operations in advance, ensuring that data is protected before any potential exposure occurs, rather than attempting to secure it after transmission.
2Object-affected harmful factors
If encryption and security measures are implemented, then user information is protected, but system complexity increases
Solution Approach 1:
The patent merges the security engine with the sensor hub into an integrated system on chip (SoC). By combining these previously separate components, the patent reduces overall system complexity while maintaining comprehensive security functionality. The merged architecture allows security operations to be performed closely at the data source without requiring separate complex security infrastructure.
Solution Approach 2:
The security engine is designed to autonomously perform authentication, encryption, and data protection operations without requiring external intervention or complex external security systems. The component serves itself by independently managing security protocols, which simplifies the overall system architecture by eliminating the need for additional external security management layers.
Data Source
AI summary
An apparatus, a system and a method for securing sensor data by a security engine circuitry of a system on chip (SoC). For example, the security engine may receive from a processor circuitry of the SoC an inter processor communication (IPC) request to secure sensor data, and may send to an integrated sensor hub (ISH) of the SoC an IPC request to receive sensor data. The ISH may collect sensor data from one or more internal and/or external sensors, and may send the collected sensor data to the security engine. The security engine may receive the collected sensor data from the ISH, may secure the collected sensor data, and may send secured sensor data to the processor circuitry.
