Solution Overview

Problem

Existing methods for configuring Hardware Security Modules (HSMs) in networked environments are inefficient and laborious, relying on untrusted devices for manual configuration, which lacks security and automation, especially in cloud-based setups.

Innovation Solution

A system and method for End-to-End trusted HSM setup using a secure device, involving certificate-based authentication and multi-factor authentication (MFA) to program secure elements with network configuration information, allowing automated IP address assignment and secure communication channels for HSM initialization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual configuration using untrusted devices is used, then HSM can be set up, but security is compromised and labor is excessive

Engineering Contradiction:

ImprovesecurityVSAvoidmanual configuration labor

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The HSM performs self-configuration by automatically detecting network parameters and generating cryptographic keys without requiring manual intervention. The device uses its own embedded secure element to store configuration data and autonomously completes the setup process, eliminating the need for operators to manually configure each HSM while maintaining security through hardware-based protection.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

An automated provisioning system acts as an intermediary between the HSM and the network infrastructure. This system automatically pushes configuration parameters to the HSM, manages cryptographic key generation, and coordinates the setup process, thereby eliminating manual configuration labor while maintaining security through controlled automated access.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If automated configuration is implemented, then labor is reduced, but trust and security verification become challenging

Engineering Contradiction:

Improveconfiguration automationVSAvoidtrust verification

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The secure element is pre-provisioned with cryptographic keys and authentication credentials before the HSM is deployed. This preliminary action ensures that trust verification mechanisms are already in place before automated configuration begins, allowing the system to automatically verify identities and establish secure communications without compromising security.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses temporary, single-use cryptographic tokens and ephemeral security credentials for automated authentication. These short-living security objects are generated specifically for the configuration process and discarded afterward, providing strong trust verification for automation without requiring long-term security compromises.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If serial cable connection is used for configuration, then direct control is achieved, but device complexity increases and cost rises

Engineering Contradiction:

Improvedirect controlVSAvoidphysical connection requirements

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical serial cable connection system with wireless or network-based communication protocols. The HSM uses its network interface to receive configuration commands and transmit status information, eliminating the need for physical serial connections while maintaining direct control capabilities through software-based communication channels.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Measurement precision

If each HSM is configured individually, then precise control is maintained, but productivity decreases

Engineering Contradiction:

Improveconfiguration controlVSAvoidsetup speed

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The automated provisioning system implements a universal configuration interface that can simultaneously manage multiple HSMs with different requirements. The system maintains precise control over each device's specific configuration parameters while operating on multiple devices in parallel, thereby achieving both individualized configuration control and high throughput productivity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The configuration process is segmented into independent, standardized tasks that can be executed simultaneously across multiple HSMs. Each HSM receives its own configuration package with device-specific parameters, allowing parallel processing while maintaining precise control over individual device settings through structured configuration data.

Inventive Principle:

Principle #1Segmentation
