Endpoint Access Control for PCIe IDE Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security methods for high-speed interconnect technologies, such as PCIe, face challenges in controllability and performance, particularly in maintaining data integrity and confidentiality while minimizing overhead.
Innovation Solution
Integrating selective components of the Integrity and Data Encryption (IDE) mechanism into the Access Control Services (ACS) framework at endpoint devices, focusing on key setup and exchange without full encryption, to enhance security and reduce performance penalties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full IDE encryption mechanism is implemented, then data integrity and confidentiality are improved, but computational overhead and performance penalties increase
Solution Approach 1:
The patent extracts and implements only the essential access control and authentication components of IDE into the ACS framework, separating these from the full encryption mechanism. This allows security functionality to be maintained while excluding the computationally intensive encryption operations, thereby resolving the contradiction between security reliability and computational performance
Solution Approach 2:
The patent segments the IDE mechanism into distinct functional components: access control services, key setup and exchange, and authentication. By implementing only the necessary components for security establishment rather than the complete encryption pipeline, the system achieves security functionality with reduced computational overhead
2Productivity
If selective IDE components are integrated into ACS framework, then performance penalties are reduced, but security coverage may be compromised
Solution Approach 1:
The patent applies partial action by implementing only the necessary subset of IDE components (access control, key exchange, authentication) rather than the complete encryption mechanism. This partial implementation provides sufficient security coverage for the intended use case while avoiding the performance penalties of full IDE, achieving an optimal balance between security and performance
3Reliability
If key setup and exchange component is established, then authentication security is improved, but device complexity increases
Solution Approach 1:
The patent merges the key setup and exchange functionality directly into the existing ACS framework, combining authentication security features with access control services. This integration eliminates the need for separate, complex authentication subsystems while maintaining strong security, thereby reducing overall device complexity
Data Source
AI summary
systems, computer program products, and methods are described for an endpoint device configured for secure data transmission within a network. An example endpoint device may include a network interface configured to receive a communication request from a peer endpoint device, and an access control unit configured to determine whether a peer endpoint device is IDE qualified based on the communication request. If the peer endpoint device is IDE qualified, the access control unit authorizes the communication request, allowing secure communication between the devices. If the peer endpoint device is not IDE qualified, the access control unit transmits the communication request to a root port for further authorization, verifying that only IDE-qualified devices are permitted to communicate directly.
