Signed Release Bundles for Secure Software Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software deployment methods are inefficient, resource-intensive, and insecure, particularly for service-oriented architectures requiring multiple updates across different locations, due to network connectivity, bandwidth, and security challenges.
Innovation Solution
A system for generating a release bundle with checksums and metadata, attaching a signature to make it immutable, and transmitting it to node devices for secure and efficient software distribution, verifying the bundle's integrity and source before storing the files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If software is deployed via network, then deployment speed and efficiency are improved, but security risks and unauthorized updates increase
Solution Approach 1:
The system performs preliminary verification actions by checking digital signatures and checksums before software deployment. The server verifies the signature of the software bundle and calculates checksums of individual files to ensure integrity and authenticity, preventing unauthorized updates before they can be installed.
Solution Approach 2:
The patent introduces a verification intermediary layer between network transmission and software installation. This intermediary checks digital signatures and checksums as a middle step, ensuring that only authenticated and intact software bundles are deployed, thus mediating between deployment efficiency and security requirements.
2Reliability
If physical connection is used for software deployment, then security and control are improved, but deployment time and resource intensity increase
Solution Approach 1:
The patent replaces the mechanical physical connection system with a digital verification system. Instead of requiring physical media transfer, the system uses digital signatures and checksums to verify software integrity, eliminating the time-consuming physical connection process while maintaining security through cryptographic verification.
3Productivity
If network deployment is used, then deployment speed is improved, but network bandwidth and connectivity requirements increase
Solution Approach 1:
The server performs preliminary verification of software bundles and prepares checksums in advance. By pre-verifying signatures and calculating checksums before deployment, the system reduces the network bandwidth required during actual installation, as only verified software needs to be transmitted without repeated verification during the process.
Data Source
AI summary
The present disclosure provides a method, system, and device for distributing a software release. To illustrate, based on one or more files for distribution as a software release, a release bundle is generated that includes release bundle information, such as, for each file of the one or more files, a checksum, meta data, or both. One or more other aspects of the present disclosure further provide sending the release bundle to a node device. After receiving the release bundle at the node device, the node device receives and stores at least one file at a transaction directory. After verification that each of the one or more files is present/available at the node device, the one or more files may be provided to a memory of a node device and meta data included in the release bundle information may be applied to the one or more files transferred to the memory.
