Secure Application Execution via Immutable Device Profile Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enterprise applications face challenges in securing sensitive transactions from fraud and cyber attacks, particularly in distributed environments where parts of the application execute across private networks and IoT devices, with existing solutions failing to effectively validate and authenticate device configurations.
Innovation Solution
A secure application management system that builds an initial profile of wireless communication devices, storing it as an immutable record, and continuously validates the device's current profile against the initial one to ensure authenticity and integrity, using a secure application manager to manage API requests and enforce secure execution environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the application is distributed across multiple devices and networks to improve accessibility and functionality, then the versatility and ease of operation are improved, but the security and reliability are worsened due to increased exposure to fraud and cyber attacks
Solution Approach 1:
The application is segmented into two distinct parts: a secure core component executing on controlled servers and a client interface executing on user devices. This segmentation allows the application to be distributed for accessibility while maintaining security by isolating sensitive operations in the secure core from untrusted external environments.
Solution Approach 2:
A device profile verification mechanism acts as an intermediary between the distributed client devices and the secure core. This intermediary validates device configurations and establishes trust before allowing communication, enabling distributed access while filtering out potentially malicious connections.
2Reliability
If device profile validation is implemented to improve security and detect unauthorized changes, then the reliability and protection from cyber attacks are improved, but the device complexity and difficulty of operation are worsened
Solution Approach 1:
The complete device profile is captured and stored as an immutable reference state during the initial application installation, before any potential security compromises can occur. This preliminary action establishes a baseline for future validation without requiring ongoing complex monitoring, as the reference state is already predetermined and stored.
Solution Approach 2:
A cryptographic hash of the device profile is created and stored on the server as a lightweight reference copy. Instead of storing or comparing complete device configurations, the system uses this hash copy for efficient validation, reducing the complexity of profile management while maintaining validation capability.
3Reliability
If continuous validation of device profiles is performed to improve security monitoring, then the ability to detect hacks and unauthorized changes is improved, but the use of energy and computational resources are worsened
Solution Approach 1:
The system replaces continuous computational comparison of device profiles with a cryptographic hash verification mechanism. Instead of mechanically comparing entire device states, the system uses mathematical hash functions to validate device integrity, dramatically reducing computational energy requirements while maintaining detection capability.
Solution Approach 2:
The device profile hash serves multiple functions simultaneously: it acts as a security validation key, a device identification marker, and a change detection mechanism. This multi-functionality eliminates the need for separate validation systems, reducing overall computational overhead and energy consumption.

AI summary
A method of managing execution of a secure application is disclosed. The method comprises receiving an initial profile of an wireless communication device (WCD) by a secure application manager executing on a computer system, storing the initial profile by the secure application manager in a datastore; receiving a request comprising a current profile of the WCD by the secure application manager from an API of a secure application executing on the WCD to invoke an operation of a secure application; comparing the current profile of the WCD by the secure application manager to the initial profile of the WCD stored in the immutable record in the datastore; and in response to determining that the current profile of the WCD matches the initial profile of the WCD, passing the request to invoke an operation of the secure application by the secure application manager to the secure application for execution.
