Aggregate-Signcryption for Securing Smart Camera IoT Applications
Subhan Ullah, F. Russo, Lucio Marcenaro, Bernhard Rinner · 2018
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-efficiency 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 specific node called cluster head. Aggregate-signcryption reduces the communication overhead and requires fewer steps for the unsigncryption as compared to individual signcryption.
