Zero-Touch Device Provisioning via Identity Attestation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of shared devices in managed networking environments is often cumbersome and time-consuming due to the need for extensive IT administrator involvement in configuring each device for network access, requiring manual intervention and user involvement for security identifier entry, which slows down the deployment process.
Innovation Solution
Implementing a zero-touch deployment structure where devices are automatically configured upon powering on, using a cloud-stored configuration profile and attestation by a management server to verify device identifiers, allowing devices to connect to the network without manual user intervention, and pre-registering device identifiers for secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of devices by IT administrators is performed, then secure network access is ensured, but deployment time and complexity increase significantly
Solution Approach 1:
Device identifiers are pre-registered with the management server before devices are deployed to users. When a device is powered on, it automatically communicates its pre-registered identifier to the management server, which has already stored the corresponding security credentials and network configuration. This preliminary registration eliminates the need for manual configuration during deployment, enabling rapid automated enrollment while maintaining security through pre-vetted device identification.
2Reliability
If user involvement is required for security identifier entry, then device security is maintained, but ease of operation deteriorates
Solution Approach 1:
The device performs self-enrollment by automatically providing its pre-registered identifier to the management server upon initial power-on. The management server autonomously retrieves the corresponding security credentials and configuration, then pushes them to the device without requiring user intervention. This self-service mechanism maintains security through pre-registered device identification while dramatically improving ease of operation by eliminating manual security identifier entry.
3Manufacturing precision
If extensive IT administrator involvement is required, then proper device configuration is ensured, but productivity decreases
Solution Approach 1:
A management server acts as an intermediary between devices and the network infrastructure. The server stores pre-registered device identifiers, security credentials, and network configuration parameters. When devices enroll automatically, the management server mediates the configuration process by retrieving appropriate settings from its database and pushing them to devices, ensuring configuration accuracy without requiring IT administrator involvement for each device.
Solution Approach 2:
All configuration parameters, security credentials, and network settings are prepared and stored in the management server's database before devices are deployed. This preliminary preparation of configuration data enables the management server to automatically configure devices upon enrollment, ensuring accuracy through pre-vetted configuration parameters while enabling high-volume parallel deployment without IT administrator bottleneck.

AI summary
This document relates to a process for deploying devices and automatically provisioning the devices to connect to a managed network upon powering on with minimal user involvement. Upon deployment of the device to an end point, a record can be established in a management server regarding the device, which can associate device specifications with a deployment profile to be used in provisioning the device. Upon powering on of the device at the end point, the device can automatically perform attestation with the management server, which can then provision the device according to the deployment profile without additional user intervention.
