Access Control Module for Secure Network Policy Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in ensuring that computing devices comply with varying law enforcement access policies across different countries, as they lack a robust method to verify whether devices meet specific policy requirements before allowing access to networks.
Innovation Solution
The implementation of an Access Control Module within computing devices, which uses an Access Verification Public Key and a Device Signature Key to verify digital signatures and ensure compliance with external access policies, allowing authorized access while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a network access point checks authorization credentials before granting access, then network security is improved, but access complexity increases
Solution Approach 1:
The access verification public key is embedded in the access control module during device manufacturing, before the device attempts to access any network. This preliminary setup eliminates the need for complex runtime credential verification, as the device can immediately present its verification key to prove compliance with law enforcement access policies.
Solution Approach 2:
The access verification public key acts as an intermediary credential that simplifies the authentication process. Instead of verifying complex authorization credentials, the network access point only needs to verify the digital signature using the pre-embedded public key, reducing access complexity while maintaining security.
2Reliability
If digital signature verification is implemented to ensure policy compliance, then access control reliability is improved, but processing time increases
Solution Approach 1:
The access verification public key is pre-embedded in the access control module during device manufacturing. This preliminary action eliminates the need for time-consuming key exchange or certificate validation processes during network access, as the verification key is already available for immediate use.
Solution Approach 2:
The patent extracts only the essential verification function from complex authentication protocols. By using a pre-embedded public key for signature verification, the system removes unnecessary processing steps while maintaining access control reliability, significantly reducing processing time.
3Reliability
If law enforcement access policies are enforced at network access points, then policy compliance is improved, but device compatibility issues arise across different countries
Solution Approach 1:
The access verification public key serves multiple functions: it verifies device identity, proves compliance with law enforcement access policies, and enables network authentication. This universal credential works across different networks and jurisdictions, improving device compatibility while enforcing policy compliance.
Solution Approach 2:
Instead of requiring different authentication mechanisms for different countries' policies, the patent uses a universal digital signature verification approach. The same pre-embedded public key can be copied and used across all networks that enforce law enforcement access policies, ensuring both compliance and compatibility.

Methods and apparati for permitting Computing Devices 200 to safely accept Payloads 220 from External Access Entity Devices 260, and to safely access external Networks 710. In an apparatus embodiment, a Computing Device 200 contains an Access Control Module 210 comprising an Access Verification Public Key 211 and a Device Signature Key 214. The Access Control Module 210 is configured to verify authorization of an External Access Payload 220 by verifying a digital signature affixed to the Payload 220 using the Access Verification Public Key 211. The authorized External Access Payload 220 is then permitted to execute on the Computing Device 200. The Access Control Module 210 is also configured to receive from a Network Access Device 600 information associated with a Network 710 access request, and to create a plurality of digital signatures, using the Device Signature Key 214, that link said information associated with the Network 710 access request with the Access Verification Public Key 211.
