Cloud Enclave Remote Attestation for Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data security methods in software applications are insufficient to comply with the General Data Protection Regulation (GDPR), leaving organizations at risk of significant penalties due to potential data breaches and unauthorized access.
Innovation Solution
A method involving remote attestation, where a provider agent in the cloud service system requests a cryptographic quote of an instantiated enclave, verifying its integrity against a provider quote verification service, ensuring the application's security by validating the quote enclave signature against a provider attestation data storage, thereby enhancing data protection across client, service provider, and cloud systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software-based security solutions are used to encrypt data, then data protection from theft is improved, but data integrity and protection against corruption worsen
Solution Approach 1:
The patent introduces hardware-based security modules (HSMs) and secure enclaves as intermediary layers between the software application and the data storage. These hardware components act as mediators that provide cryptographic protection and integrity verification, preventing both theft and corruption by isolating the data in a physically protected environment that software cannot directly access or modify.
Solution Approach 2:
The patent combines software-based encryption with hardware-based security mechanisms to create a composite security architecture. This includes layering software encryption protocols with hardware security modules, secure enclaves, and remote attestation mechanisms, where each layer provides complementary protection against different types of threats including theft, corruption, and unauthorized access.
2Reliability
If hardware-based security solutions are used to prevent read and write access, then data integrity is improved, but system usability and flexibility worsen
Solution Approach 1:
The patent implements self-service mechanisms where the hardware security modules automatically perform cryptographic operations, integrity verification, and access control without requiring manual intervention. The system autonomously manages security policies, performs remote attestation, and handles key management, reducing the operational burden while maintaining strict security controls.
Solution Approach 2:
The patent segments the security functions into distinct modular components including hardware security modules, secure enclaves, remote attestation services, and policy management systems. This modular architecture allows different security mechanisms to be independently configured and activated based on specific operational requirements, providing flexibility while maintaining data integrity through hardware enforcement.
3Reliability
If remote attestation and quote verification are implemented, then data security compliance is improved, but computational overhead and processing time worsen
Solution Approach 1:
The patent performs remote attestation and quote verification as preliminary actions during system initialization, application deployment, and before critical data operations. By completing these computationally intensive security verification processes in advance, the system establishes trusted execution environments beforehand, avoiding repeated verification overhead during normal operations and reducing overall processing time.
