As a synchronizing force of the physical and digital worlds, the Internet of Things (IoT) debuted a decade ago and has become the innovation engine of countless businesses. The simple but remarkably specific idea of ​​collecting data from the outside and communicating it over the Internet opened up a world of opportunities for businesses in the logistics, automotive and aerospace industries. The rise of autonomous vehicles, smart airports, intelligent transport management systems, IoT-enabled smart meters, real-time tracking and efficient asset maintenance are some of the most transformative benefits that businesses in these sectors can get from IoT. Paradoxically, from a security perspective, the most powerful aspect of IoT has turned into the Achilles heel of enterprises. In no time, the ability to share data with everyone and everything ‘things’ has created cyber security threats that security teams can’t keep up with. At a time when businesses are inundated with security attacks from every angle and channel, IoT is contributing to making the attack surface significantly larger.

After more than a decade of building highly resilient IoT stacks and applications across diverse industries and use cases, security challenges related to malware and distributed denial of service (DDoS) attacks are simultaneously intensifying. . Some of the easiest targets for such attacks are unpatched and less secure connected devices.

Enter blockchain.

Blockchain’s involvement in the IoT space is changing the security narrative in businesses. In filling the security gap, blockchain has emerged as the most innovative and viable way to secure the billions of devices connected to the untapped Internet. Many companies in France are actively contributing to the adoption of blockchain and related business models. With use cases for the technology across the country, blockchain is now poised to replace the currency of security in the IoT space as well. This technology introduces the concept of a central authority (distributed database) and tamper-resistant, ledger-record entities to lock down access to multiple devices and improve the scalability of IoT implementations. Empowers. Immutable records distributed across different nodes allow users to seamlessly monitor network behaviors and performance anomalies in real-time.

Blockchain, with its decentralized and cryptographic nature, enables the authentication and security of vulnerable devices and processes associated with the IoT, and prevents the propagation of errors or disruptions throughout the network. As a result, a DDoS attack on one device does not disrupt the operation of others. Blockchain also strengthens the IoT ecosystem with cryptography, ensuring secure communication, anonymity and privacy. From a holistic perspective, blockchain offers the following benefits while securing IoT networks:

  • Tracking connected devices in an IoT network
  • Maintaining secure data records
  • Reaching a consensus to approve the transaction
  • Enabling decentralization across the network
  • Identifying, authenticating, and securing devices
  • excluding intermediaries
  • Building trust relationships between IoT devices and processes
  • Reducing operational costs

Beyond the reach of traditional security solutions

The information game changer, blockchain, is rewriting the rules of IoT security in many industries. Here’s a glimpse of how technology is shaping operations and improving business performance:

  • Logistics: Establishing smart logistics management systems that feature better security, better data access, and efficient and quick tracking and traceability.
  • Aerospace: Contributing to aviation safety and IP protection, and managing the replacement of parts for in-service aircraft, protecting flight records, maintenance conditions and other data.
  • Automotive: Improving autonomous and connected vehicles with capabilities such as automatic fuel payment, smart parking, automated traffic control; Improved and secure data exchange between devices and platforms.

Changing IoT Security Forever

IoT security vulnerabilities will continue to evolve with ever-changing regulations in France. Still, the potential to strengthen IoT security with blockchain is huge. As an ally of global enterprises, Tech Mahindra can empower French businesses with its deep technical expertise in the blockchain and IoT landscape. From enabling business strategies and systems integration to implementing plug-and-play platforms, Tech Mahindra can help enterprises prepare for the new era of cybersecurity and maintain their competitive edge. So can keep abreast of the latest developments.
