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.
智能相机是物联网 (IoT) 应用中的关键传感器，通常会捕获高度敏感的信息。因此，安全性和隐私保护是一个关键问题。本文提出了一种基于椭圆曲线 (EC) 签密的轻量级安全方法，可在单个步骤中执行数据签名和加密。我们部署签密技术来有效保护相机上的敏感数据，并确保从多个相机到多个监控设备的数据传输安全。我们的多发送方/多接收方方法提供了数据的完整性、真实性和机密性，并为整个数据生命周期中的多个接收方提供了公平的解密。它还提供了数据的可公开验证性和前向保密性。我们已经为智能相机 IoT 场景实现了无证书多接收方聚合签密保护，并比较了其运行时和通信开销与单发送方/单接收方和多发送方/单接收方设置。
