May 17th IoT security company Xage claims to develop a tamper-proof system that combines blockchain technology and digital fingerprinting technology to protect Industrial Internet of Things (IIoT) assets. This solution combines today's two hot key technologies - blockchain technology and digital hygiene - to enable organizations to understand the correct state of each device or machine and share information in the form of distributed ledgers.
Protecting Digital Assets with Fingerprinting Technology
The start-up company uses the blockchain as part of its security architecture to distribute authentication and private data across network nodes, allowing industrial systems and sensors to work safely and in scale. The key to this solution lies in the digital fingerprinting process. Digital fingerprinting attempts to display as much information as possible for each device or controller in the network. For example, a digital fingerprint stores the device's configuration data, hardware type and installed software information, CPU ID, and storage ID.
Once malware enters the system, digital fingerprinting observes changes and shuts down the device until the technician confirms that the software is legitimate.
Xage's digital fingerprinting technology creates identity and authentication information for the system. When digital fingerprints detect a change in the controller or device in real time, the technology marks and isolates suspicious components. Next, digital fingerprinting technology will create a cloud-based "Digital Twin" for every physical device in an industrial environment to check if software changes or updates are legal and allow the organization's security team to Predict new fingerprints for each device before the update occurs. In this way, “digital twins†helps staff to distinguish between real updates and disguised external threats.
Eliminate single point of failure
The core of digital fingerprinting security is its deployment on a series of distributed nodes. Xage claims that blockchain technology can eliminate the possibility of a single point of failure. If an oil company stores digital fingerprints in the traditional way, accessing these fingerprints is enough to attack the entire networked device system.
However, in theory, blockchain can help eliminate such threats while also providing a means to verify current fingerprints and new fingerprints. Therefore, comprehensively, fingerprint technology, digital copying, and distributed distribution mechanisms can provide security detection and mitigation services for networked device networks of industrial operators.
Dunage Greywood, CEO of Xage, said that with the continuous networking of industrial control systems, the use of shared networks by multiple devices will become more common, and new ways of attacking the Internet of Things will increase.
Glatterwood also pointed out that the block-chain protection fingerprint identification technology provides a tamper-proof system for the entire industrial IoT process, and provides a fail-safe layer to actively mitigate loopholes. This is the first case in the world. With the involvement of artificial intelligence, blockchain and digital twinning will evolve into new forms and applications.
