  • Secure Smart Cameras by Aggregate-Signcryption with Decryption Fairness for Multi-Receiver IoT Applications

    摘要： Smart cameras are key sensors in Internet of Things (IoT) applications and often capture highly sensitive information. Therefore, security and privacy protection is a key concern. This paper introduces a lightweight security approach for smart camera IoT applications based on elliptic-curve (EC) signcryption that performs data signing and encryption in a single step. We deploy signcryption to efficiently protect sensitive data onboard the cameras and secure the data transfer from multiple cameras to multiple monitoring devices. Our multi-sender/multi-receiver approach provides integrity, authenticity, and confidentiality of data with decryption fairness for multiple receivers throughout the entire lifetime of the data. It further provides public verifiability and forward secrecy of data. Our certificateless multi-receiver aggregate-signcryption protection has been implemented for a smart camera IoT scenario, and the runtime and communication effort has been compared with single-sender/single-receiver and multi-sender/single-receiver setups.

    摘要： Smart cameras are considered as key sensors in Internet of Things (IoT) applications ranging from home to city scales. Since these cameras often capture highly sensitive information, security is a major concern. An elliptic curve (EC) based signcryption achieves resource-ef?ciency by performing data encryption and signing in a single step. In this work, we present aggregate-signcryption which extends the EC-based signcryption approach to a cluster-based multi-camera setup. The signcrypted data from the smart cameras within a cluster is aggregated on a speci?c node called cluster head. Aggregate-signcryption reduces the communication overhead and requires fewer steps for the unsigncryption as compared to individual signcryption.
