研究目的
Investigating the performance of aggregate-signcryption for cluster-based smart camera IoT applications to reduce the communication and computation overheads.
研究成果
The study successfully implemented EC-based signcryption for the security of multiple images on smart cameras and extended it to aggregate-signcryption in a cluster-based multi-camera network, reducing communication and computation overheads. Future work will extend this to one-to-many and many-to-many communication scenarios.
研究不足
The study assumes no explicit protection of the denial of service (DoS) attacks on the other components of the system and that the monitoring device is trustworthy with private keys securely stored on it.
1：Experimental Design and Method Selection:
The study implements EC-based signcryption for securing multiple images on smart cameras and extends it to an aggregate-signcryption approach for a cluster-based multi-camera network.
2：Sample Selection and Data Sources:
Smart cameras capture images with a pre-defined QVGA resolution of 320 × 240 pixels.
3：List of Experimental Equipment and Materials:
Raspberry Pi 3 serves as platforms for the smart cameras, JRPiCam Java library for image capturing and processing, BouncyCastle as cryptographic service provider.
4：Experimental Procedures and Operational Workflow:
Signcryption is implemented using the EC-finite field of P-384 and a 256 bit AES key. The cluster head aggregates the signcrypted data.
5：Data Analysis Methods:
The computational and communication overheads are measured and compared between individual-signcryption and aggregate-signcryption.
