Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud-based hardware security module (HSM) solutions from different service providers lack interoperability, making it difficult for users to migrate cryptographic keys across different cloud environments and regions, due to varying key management and exchange protocols.
Innovation Solution
A cloud infrastructure-agnostic key exchange management system utilizing true quantum random number generation and key derivation circuitry to establish secure communication groups among HSMs hosted by different service providers, enabling secure key sharing and migration across diverse cloud environments and regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different service providers implement their own key management and exchange protocols in cloud-based HSM solutions, then each provider can optimize security and control for their specific infrastructure, but interoperability between different cloud environments and regions deteriorates, making key migration difficult
Solution Approach 1:
The patent introduces a key exchange management device that acts as an intermediary between HSMs from different service providers. This device implements a standardized key exchange protocol that translates between different providers' proprietary protocols, enabling interoperability while allowing each provider to maintain their own security implementations. The intermediary device receives key exchange requests, performs protocol translation, and facilitates secure key sharing across heterogeneous cloud environments.
Solution Approach 2:
The key exchange management device is designed with universal functionality to work with multiple different service providers and HSM implementations simultaneously. It supports multiple key exchange protocols and can adapt to different cloud infrastructure types (public, private, hybrid clouds), making it a multi-functional solution that resolves interoperability issues across diverse environments without requiring separate solutions for each provider.
2Speed
If service providers regionalize their managed HSMs for local compliance and performance, then regional performance and compliance are improved, but the ability to use the same cryptographic key across different regions deteriorates
Solution Approach 1:
The patent segments the key management system into regional HSM components that can operate independently for local performance optimization, while the key exchange management device provides a coordinating layer that enables cross-region key sharing. Each regional HSM can process cryptographic operations locally with high speed, while the management device handles the coordination of key exchange across regions, allowing both regional performance and cross-region interoperability.
3Reliability
If cloud-based HSM solutions are implemented with proprietary key management protocols, then service providers can maintain control and security, but the complexity of managing key exchange across different providers increases
Solution Approach 1:
The key exchange management device serves as an intermediary that abstracts away the complexity of multi-provider key management. It implements a standardized interface that simplifies the key exchange process for users, while internally handling the complexity of protocol translation and coordination between different service providers' proprietary systems, thereby reducing operational complexity without sacrificing provider control.

AI summary
Systems, apparatuses, methods, and computer program products are disclosed for hardware security module communication management. An example method includes deriving, by a first HSM, a first cryptographic key based on an initial key and a first set of seed bits. The method also includes receiving a message comprising a second cryptographic key from a key exchange management device, wherein the second cryptographic key is associated with a second HSM. The method also includes deriving, a third cryptographic key based on the first cryptographic key and the second cryptographic key, wherein deriving the third cryptographic key establishes secure communication between the first HSM and the second HSM based on the second HSM having also derived the third cryptographic key. The method also includes performing, a first cryptographic data protection action using the third cryptographic key.
