Secure Smart Cameras by Aggregate-Signc...

Smart cameras are key sensors in Internet of Things (IoT) applications and often capturehighly sensitive information. Therefore, security and privacy protection is a key concern. This paperintroduces 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 signcryptionto efficiently protect sensitive data onboard the cameras and secure the data transfer from multiplecameras to multiple monitoring devices. Our multi-sender/multi-receiver approach providesintegrity, authenticity, and confidentiality of data with decryption fairness for multiple receiversthroughout the entire lifetime of the data. It further provides public verifiability and forward secrecyof data. Our certificateless multi-receiver aggregate-signcryption protection has been implementedfor a smart camera IoT scenario, and the runtime and communication effort has been compared withsingle-sender/single-receiver and multi-sender/single-receiver setups.
