Endpoint Device Credential Packet for Scaled Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for authenticating endpoint devices in networked computing environments require manual intervention, making them inefficient for large-scale deployments and preventing system administrators from registering large quantities of devices.
Innovation Solution
A computer-implemented method that generates a credential data packet using a resource file with encryption keys, encrypts it with a device key, and signs it with an endpoint device management key, allowing endpoint devices to securely register and authenticate without intermediary systems through a trusted communication channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual authentication codes are used for device registration, then security is maintained, but registration efficiency deteriorates for large-scale deployments
Solution Approach 1:
The endpoint device autonomously generates authentication credentials using its device key and resource file without requiring manual administrator intervention. The device self-registers by creating and transmitting credential data packets automatically, enabling bulk device registration while maintaining security through cryptographic signatures.
Solution Approach 2:
The system pre-distributes resource files containing encryption keys to endpoint devices before registration. This preliminary provisioning enables devices to self-authenticate without real-time administrator involvement, resolving the contradiction between security (pre-configured keys) and efficiency (automated registration).
2Productivity
If automated authentication is implemented, then registration efficiency improves, but system complexity increases due to cryptographic key management
Solution Approach 1:
The resource file serves multiple functions: it stores the device key for authentication, contains the EDM key for signing credentials, and provides encryption capabilities. This multi-functional design simplifies the overall system architecture by consolidating cryptographic operations into a single resource file, reducing operational complexity despite automated authentication.
3Speed
If intermediary systems are eliminated for direct device registration, then authentication speed improves, but security risks increase
Solution Approach 1:
The credential data packet acts as a cryptographic intermediary between the endpoint device and the application. It encapsulates authenticated identity information signed by the EDM key, enabling direct device-to-application communication while maintaining security through the intermediary credential structure that verifies device identity without requiring continuous administrator mediation.
