eSIM Resource Reservation for Secure Shared Workstation Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for accessing physical computing resources in shared environments are inefficient and vulnerable to security threats due to lack of device authentication and inefficient allocation, particularly in distributed workforces with varying schedules and needs.
Innovation Solution
Implementing an embedded subscriber identity module (eSIM) on computing devices to manage resource reservations through unique device profiles, ensuring secure and efficient access by authenticating devices and users via wireless network connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If freely available workstations are utilized without authentication, then accessibility and ease of operation are improved, but security vulnerabilities and resource allocation efficiency deteriorate
Solution Approach 1:
The system performs preliminary authentication of computing devices before granting access to physical computing resources. Device profiles are pre-configured with authentication credentials, and the reservation service pre-validates device authorization before allowing connection to workstations, printers, or other shared resources. This preliminary verification eliminates security vulnerabilities while maintaining ease of operation for authorized devices.
2Reliability
If device authentication is implemented, then security and resource allocation efficiency are improved, but device complexity and system complexity increase
Solution Approach 1:
The system uses embedded subscriber identity modules (eSIM) to store and manage device profile copies that contain authentication credentials. Instead of complex centralized authentication servers, each computing device holds a verified copy of its authentication profile, enabling self-authentication. This approach maintains high security while reducing system complexity by distributing authentication capabilities to individual devices.
3Ease of operation
If first-come-first-serve access is used, then ease of operation is improved, but resource allocation efficiency and user satisfaction deteriorate for distributed workforces
Solution Approach 1:
The reservation service enables users to pre-book physical computing resources in advance by submitting reservation requests with desired time slots and resource types. The system pre-allocates resources to authorized devices based on these reservations, ensuring that distributed workforce members can secure needed workstations, printers, or meeting room equipment before arrival. This maintains operational simplicity while dramatically improving resource allocation efficiency and user satisfaction.

AI summary
An example computing device accesses a resource allocation network service utilizing a wireless network connection in accordance with embedded SIM (eSIM) functionality to identify and reserve computing resources. The computing device transmits a request to the resource allocation server that includes computing device profile information stored in the eSIM. The resource allocation network service processes the requests and receives additional profile information from the identified physical computing resource. The resource allocation network service then establishes a reservation and generates allocation information that includes credential information and is sent to the requesting computing device and the physical computing resource. When the computing device attempts to access the computing resource (e.g., the workstation), the physical computing resource authenticates the computing device based allocation information transmitted by the computing device.
