Blockchain-Enabled Quantum Encryption Scheme for Securing Next-Generation IoT Networks

The Internet of Things (IoT) is expanding swiftly, offering ease in everyday life. As the IoT systems produce enormous volumes of data, frequently encompassing private and confidential information, it is imperative to ensure their security. To ensure the security in IoT systems, we present a blockchain-enabled data encryption scheme utilizing quantum computing. This consensus mechanism eliminates the need for outside central service providers and encrypts data and accumulates converted cipher-text using consensus nodes acting as proxy service nodes. This approach alleviates the constraints associated with storing and sharing private encrypted information securely over a decentralized network. The suggested protocol possesses security attributes to counter replay attacks, side-channel attacks, Sybil attacks, and eavesdropping attacks, while mitigating tampering risks through targeted verification. Experimental results demonstrate an accuracy rate of 93.33%, with any discrepancies attributed to quantum device errors. The proposed protocol combines quantum encryption and blockchain-based security to create a scalable, decentralized, and resilient framework for securing IoT data sharing.
