Automated Software Upgrade Server with Public Key Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large computer networks, manually upgrading software on numerous nodes is inefficient and undesirable, as it requires user intervention and can be time-consuming, especially in datacenters with many nodes.
Innovation Solution
An automated system utilizing an upgrade server that authenticates and downloads new software versions using public keys, ensuring validity and compatibility, and a control engine that manages installation, tracking, and analysis, allowing for stable software deployment across nodes while reverting if issues arise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual user authorization is used for software upgrades on each node, then software upgrade security and control are improved, but upgrade efficiency and time consumption deteriorate significantly in large networks
Solution Approach 1:
The system implements self-service automation where the upgrade server automatically performs software package authentication, node identification, package download, and installation execution without requiring manual user intervention on each node. The control engine on each node autonomously communicates with the upgrade server to complete the upgrade process, eliminating the need for users to manually authorize each upgrade while maintaining security through automated cryptographic verification.
2Productivity
If automated download and installation is implemented, then upgrade efficiency is improved, but system complexity and authentication requirements worsen
Solution Approach 1:
The system performs preliminary actions by pre-configuring cryptographic authentication mechanisms (public key infrastructure) during software package creation and node initialization. The upgrade server stores authentication keys and node identification information in advance, so that when automated upgrades are executed, the complex authentication processes are already prepared and can be performed automatically without adding operational complexity to the upgrade execution phase.
3Reliability
If comprehensive authentication and verification processes are implemented, then software package validity and security are improved, but processing time and operational complexity worsen
Solution Approach 1:
The system replaces manual mechanical authentication processes with automated cryptographic verification mechanisms. The upgrade server uses public key infrastructure to automatically verify software package signatures and authenticate node identities through cryptographic operations, eliminating the need for manual verification steps. This substitution maintains comprehensive security checks while reducing processing time by automating what would otherwise require lengthy manual procedures.

AI summary
Systems, methods, and computer-readable media are provided for automatically downloading and launching a new version of software package on components in a network environment. In some examples, an upgrade server of a network environment keeps a copy of all versions of software packages running on nodes or sensors of the network environment, identifications of corresponding nodes or sensors, and public keys associated with the software packages. The upgrade server can authenticate a new version of a software package using a two-step process.
