Method for secure machine data communication network setup
The patent US12047495B2 outlines a method for the initial setup of a machine data communication network, focusing on the secure management of digital identities and communication between network units. The process begins with a network unit equipped with a hardware component that possesses a digital identity, generated through a signature based on a private key. This private key is securely stored in a hardware security module, while a corresponding public key is disclosed to a communication partner for identity verification. The public key is then transferred to an identification device within the network unit, which is separate from the hardware security module. An intelligent contract is utilized to save the public key and facilitate communication with the partner, with the contract transmitted via distributed ledger technology to ensure secure and verifiable interactions.
Additionally, the patent describes methods for managing changes in configurations throughout the lifecycle of the network unit, including the storage of various types of information such as permission details, software versions, and system configurations within the intelligent contract. The intelligent contract can be generated using Corda and is designed to support communication with multiple partners, allowing for cross-verification among devices. The patent also addresses the process of replacing hardware components within the network unit, detailing a key replacement process that updates the public key associated with the new component while maintaining the integrity of the intelligent contract. Overall, the patent emphasizes the integration of security measures and distributed ledger technology to enhance the reliability and efficiency of machine data communication networks.
