LAN Server Automated Certificate Issuance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for delivering and authenticating trusted security certificates in computer systems often require secondary channels, which can be cumbersome and lack automation, especially for two-way authentication within local area networks.
Innovation Solution
A local area network server issues security certificates to client devices through a network transaction, using a self-signed or trusted security certificate for automated two-way authentication and encryption, eliminating the need for secondary authentication mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security certificates are delivered through secondary channels (postal mail, courier), then certificate authentication reliability is improved, but device complexity and operational ease deteriorate due to manual delivery processes
Solution Approach 1:
The patent replaces the mechanical secondary channel delivery system (postal mail, courier) with an electronic network-based certificate issuance system. The server automatically generates and transmits certificates through network transactions, eliminating the need for physical delivery mechanisms while maintaining authentication reliability through cryptographic verification.
Solution Approach 2:
The server automatically issues certificates to client devices through network transactions without requiring manual intervention from certificate authorities or physical delivery. The system performs self-service certificate issuance and verification, where the server both issues and validates certificates through automated network-based authentication processes.
2Productivity
If automated network-based certificate issuance is implemented, then productivity and ease of operation are improved, but certificate trust verification becomes more difficult
Solution Approach 1:
The patent implements a feedback mechanism where the server verifies client device identities through network transactions before issuing certificates. The server receives authentication requests, verifies device identities, and provides feedback by issuing certificates only to verified devices. This automated feedback loop maintains trust verification while enabling efficient certificate issuance.
Solution Approach 2:
The server acts as an intermediary between client devices and the certificate validation process. It mediates the authentication by verifying device identities and issuing certificates that serve as trusted intermediaries for future communications, simplifying the trust verification process while maintaining security.
3Adaptability or versatility
If self-signed or trusted certificates are used on the server, then adaptability is improved, but measurement precision of certificate authenticity deteriorates
Solution Approach 1:
The patent allows the server to use different certificate types (self-signed or trusted certificates) as configurable parameters. The system adapts to different security requirements by changing the certificate authenticity parameter, where self-signed certificates provide adaptability for various deployment scenarios while trusted certificates provide higher authenticity verification precision when available.
Data Source
AI summary
A local area network server may issue security certificates to client devices on the network for two-way authentication across the network. The certificates may be issued through a transaction performed over the network and, in some cases, may be automated. The server may have a self signed or a trusted security certificate which may serve as a basis for issuing certificates to various clients. After a certificate is issued, future communications on the network may be authenticated by both the server and client, and the communications may be encrypted using the certificates.
