Key Escrow Server for Synchronized Encryption Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current encryption key management systems face synchronization issues between device-level and communication-level management, leading to loose controls and potential breakdowns in communication security, particularly in public key infrastructure and enterprise key management.
Innovation Solution
A client-based service integrates local applications, servers, and infrastructure with an applied key management system, enabling automated key file collection, secure storage, and centralized escrow of encryption keys based on policies, using a Hardware Security Module or key management server for secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device-level encryption key management is implemented, then local security control is improved, but synchronization with communication-level management deteriorates
Solution Approach 1:
The patent introduces a key escrow server as an intermediary between device-level key management and communication-level management. The server receives, stores, and manages encryption keys escrowed from multiple devices, enabling centralized control while maintaining device autonomy. This mediator resolves the synchronization conflict by providing a central coordination point without eliminating local key management capabilities.
2Reliability
If centralized key management is implemented, then communication security control is improved, but device autonomy and local control deteriorate
Solution Approach 1:
The patent segments key management into two independent but coordinated functions: local key generation and storage on devices, and centralized escrow and management on the server. Each device maintains autonomous control over its local keys while the server provides centralized oversight. This segmentation allows both device autonomy and centralized control to coexist without conflict.
3Productivity
If automated key collection and escrow is implemented, then key management efficiency is improved, but system complexity deteriorates
Solution Approach 1:
The patent implements self-service mechanisms where devices automatically generate, protect, and escrow their own encryption keys without requiring manual intervention. The key escrow server provides automated registration and storage services. This automation improves efficiency by eliminating manual key management tasks while the standardized protocols keep system complexity manageable.

AI summary
Embodiments described herein relate to apparatuses and methods for registering and storing a local key associated with a local application of a communication device, including, but not limited to, receiving a request from the communication device to register and store the local key, evaluating the request based on at least one first policy, and sending the request to register and store the local key to a secure key storage.
