Solution Overview

Problem

Existing data processing systems face challenges in securely managing and efficiently provisioning, validating, and removing management controller enhanced devices (MCEDs) due to the need for secure communication and credential management, which are vulnerable to snooping attacks and lack portability between different systems.

Innovation Solution

A communication and credential management system is implemented using a secured and unsecured communication channel between the host BMC and MCEDs, ensuring secure encryption key transmission and credential management, including provisioning, validity, and removal processes to enhance security and portability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If secure communication channels and encryption key transmission are implemented between host BMC and MCEDs, then security against snooping attacks is improved, but device complexity and communication overhead increase

Engineering Contradiction:

ImprovesecurityVSAvoidcommunication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The communication system is segmented into two distinct channels: a first communication channel for transmitting secure encryption keys and a second communication channel for transmitting unsecured communications. This segmentation allows the patent to implement security measures selectively on the key transmission channel while keeping the device management channel simpler and more efficient.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The host BMC acts as an intermediary that manages the secure transmission of encryption keys to MCEDs through the first communication channel. This intermediary role enables centralized security management, where the host BMC controls key distribution and credential validation without requiring complex security implementations in each MCED.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If credential management systems are implemented for MCED provisioning and validation, then security and portability are improved, but the complexity of device management increases

Engineering Contradiction:

ImproveportabilityVSAvoidmanagement system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The credential management system implemented in the host BMC provides universal functionality for provisioning, validating, and managing MCEDs across different data processing systems. This universal credential manager enables MCEDs to be portably deployed between systems while maintaining security, as the host BMC handles all credential-related operations rather than requiring system-specific implementations in each MCED.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs preliminary credential provisioning and validation actions during MCED initialization and deployment. By pre-configuring encryption keys and credentials through the first communication channel before MCED operational use, the system simplifies subsequent device management operations and enables seamless portability without requiring complex runtime security decisions.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If separate secured and unsecured communication channels are used for different purposes, then security is improved, but loss of time due to channel selection and management increases
