Centralized Cryptographic Management for Digital Certificate Lifecycle Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of digital certificates is inefficient due to their fixed validity period, requiring frequent renewal and manual administrative efforts across multiple devices, which can lead to errors and increased administrative burdens.
Innovation Solution
A centralized cryptographic management system that uses certificate management agents installed on client devices to manage the lifecycle of digital certificates, including configuration, renewal, and validation, with a server-based system for centralized control and automation of certificate management processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital certificates are provisioned for a fixed period of time, then certificate validity is ensured, but frequent renewal is required increasing administrative burden
Solution Approach 1:
The certificate management agent automatically monitors certificate expiration dates and initiates renewal processes without human intervention. The system self-manages the entire certificate lifecycle including generation, installation, monitoring, and renewal, eliminating the need for manual administrative efforts while ensuring continuous validity.
Solution Approach 2:
The system proactively monitors certificate expiration dates and initiates renewal processes before certificates expire. By performing preliminary actions (monitoring and pre-renewal), the system prevents certificate expiration issues and ensures continuous validity without requiring reactive manual intervention.
2Ease of operation
If manual administrative efforts are used for certificate management across multiple devices, then certificate provisioning is possible, but errors increase and administrative burden increases
Solution Approach 1:
The certificate management agent enables devices to self-provision and self-manage certificates automatically. The agent handles certificate generation, installation, and renewal locally on each device without requiring manual administrative intervention, thereby eliminating human errors while maintaining ease of operation.
Solution Approach 2:
The certificate management agent acts as an intermediary between the server and the local system components. It receives configuration parameters from the server, automatically generates and manages certificates locally, and reports status back to the server, thereby automating the process and eliminating manual errors.
3Extent of automation
If centralized management system is implemented, then automation is improved, but system complexity increases
Solution Approach 1:
The system is segmented into distinct functional modules: a server component for centralized configuration management and a client-side certificate management agent for local execution. This segmentation distributes complexity, allowing the server to handle high-level policies while the agent handles local automation, thereby achieving high automation without overwhelming central complexity.
Solution Approach 2:
The certificate management agent serves as an intermediary that simplifies the interaction between the centralized server and local devices. It translates server configuration parameters into local actions and reports status back to the server, thereby enabling automation while managing system complexity through layered architecture.

AI summary
A system implemented on a server computer for managing digital certificates includes a certificate management agent module, a digital certificate processing module and a configuration module. The certificate management agent module processes requests to create a plurality of certificate management agents. Each of the certificate management agents is configured to manage a lifecycle of a digital certificate for a client electronic device. The digital certificate processing module processes requests from the certificate management agent module for digital certificates for the plurality of certificate management agents. The configuration module receives and processes configuration parameters for the certificate management agents and for the digital certificates.
