Solution Overview

Problem

Existing systems for digital asset provisioning in computerized devices face challenges such as network connectivity failures during production, leading to temporary halts in manufacturing, and the need for secure, offline provisioning to prevent unauthorized software updates or tampering.

Innovation Solution

A security credential management system (SCMS) with a certificate authority that generates and provisions digital assets offline, using a distribution appliance with a hardware security module to ensure secure communication and provisioning without an external network connection, and logs provisioning activities for audit and authorization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a centralized SCMS is used for digital asset provisioning, then security and authorization are improved, but network connectivity requirements cause production halts during outages

Engineering Contradiction:

Improvesecurity of digital asset provisioningVSAvoidcontinuous manufacturing capability

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system segments the centralized SCMS into a distributed architecture where local provisioning systems operate as independent units capable of functioning without constant central connection. Each local system maintains security credentials and can provision devices autonomously, dividing the monolithic centralized model into modular segments that tolerate network disconnections.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-provisioning local provisioning systems with security credentials, certificates, and operational parameters before network outages occur. These pre-loaded resources enable the local systems to immediately continue provisioning operations during connectivity failures without waiting for central authorization or key distribution.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If network connectivity is required for SCMS, then centralized security management is improved, but manufacturing productivity decreases during outages

Engineering Contradiction:

Improvecentralized security managementVSAvoidproduction halt duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system applies beforehand cushioning by maintaining local caches of security credentials, digital certificates, and provisioning parameters that cushion the impact of network outages. These pre-stored resources act as a buffer, allowing the system to continue operating during connectivity failures without immediate production halt.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The system ensures continuity of useful action by designing the provisioning process to continue uninterrupted during network outages through local autonomous operation. The useful action of device provisioning maintains continuous flow without requiring external network support, eliminating production halts and time loss during connectivity issues.

Inventive Principle:

Principle #20Continuity of useful action

3Productivity

If offline provisioning is implemented, then continuous manufacturing is improved, but security verification capabilities are reduced

Engineering Contradiction:

Improvecontinuous manufacturing capabilityVSAvoidsecurity verification of digital assets

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system implements self-service by enabling local provisioning systems to autonomously verify and issue digital assets without requiring external SCMS validation during offline operation. The local systems use pre-loaded security credentials and certificates to self-verify and self-issue, maintaining security verification capabilities independently during network disconnections.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system applies parameter changes by switching the operational mode of security verification between online (SCMS-dependent) and offline (local-autonomous) states. The verification parameters and validation mechanisms change dynamically based on network availability, allowing the system to maintain security verification capability in both connected and disconnected states through different verification parameter sets.

Inventive Principle:

Principle #35Parameter changes

AI summary

A system for offline generation of digital assets includes: a security credential management system (SCMS) that is operable to generate and conditionally transmit digital assets; and a certificate authority communicatively connected to the SCMS by a communication network, the certificate authority being operable to receive the digital assets from the SCMS. The certificate authority is operable to securely provision a plurality of computerized devices based on the received digital assets, the certificate authority intermittently connects to the SCMS to receive the digital assets, the certificate authority is operable to securely provision the plurality of computerized devices while disconnected from the SCMS, and the provisioning by the certificate authority while disconnected from the SCMS is limited by a policy associated with the certificate authority.
