Robotics are increasingly used in a wide variety of industries, such as healthcare, manufacturing and logistics. As robots handle more sensitive tasks and data, ensuring their security becomes critical.
Vulnerabilities in robotics systems can lead to significant risks, including breaches of personal information, compromised operational safety, and unauthorised control. Fortunately, blockchain technology offers a robust solution.
While blockchain is best known for its association with crypto trading, its decentralised and immutable structure can significantly enhance the security of robotics. We explain some key ways how below.
Immutable audit trails
Each transaction or action taken by a robot can be recorded on a blockchain ledger, whether it’s moving, collecting data or performing maintenance. Once a block is added, it becomes virtually impossible to modify without consensus from all parties involved in the system.
By using this transparent and tamper-proof audit trail, you ensure that any unauthorised changes or attempts to manipulate your robots’ behaviour are flagged. This gives you confidence that every action is securely recorded, allowing you to identify exactly when and where potential security breaches occur.
Secure data sharing
Robotics often need to share information with external systems or other robots, which presents security risks. In the case of sensitive data like health records in medical robots or operational instructions in industrial robots, there’s a chance it could be intercepted or corrupted. Blockchain addresses this issue by encrypting information and sharing it through secure, peer-to-peer channels.
With blockchain’s decentralised structure, no single entity controls the flow of information. Instead, data is broken into encrypted blocks and distributed across the network, preventing interception by outside attackers. As a result, you can confidently share information between robots and external systems without exposing it to common threats, such as man-in-the-middle attacks.
Verifiable interactions
As robots interact with each other, humans or other systems, guaranteeing legitimate interplay is vital for security. Blockchain enables you to verify all interactions through cryptographic keys, which confirm identities and authorisations. For instance, a robotic arm on an assembly line can verify that its commands come from an authorised controller and not a hacker trying to disrupt production.
This verification process is swift and automatic, reducing the chances of unauthorised interventions while keeping operations running smoothly. By using blockchain, you not only enhance security but also foster trust in the contact between humans and machines.
Embracing blockchain’s benefits for robotics can help lay a robust foundation for the future, where increasingly advanced robots operate with enhanced trust and resilience – making sure that as automation evolves, its security measures advance in tandem to meet emerging cyber challenges.
