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.

“…Later, Fan and Tseng [18] proposed an anonymous IMRE scheme and the receiver of the scheme has the capability of identity verification, but the efficiency is not high because of the excessive bilinear parings operations in the scheme. Then, Pang et al [19] put forward an absolutely cryptonymous IMRS proposal which can realize the anonymity of the receiver and sender. Gradually, people have found a serious problem that these multireceiver schemes have key escrow problems because they cannot block malicious key generation center (KGC) attacks.…”

Air pollution, water pollution, soil erosion, land desertification, and other environmental issues are becoming more and more serious. And ecological security has become a key issue for the sustainable development of the world, so research on ecology has received more and more attention. At present, ecological data is collected and stored separately by various departments or agencies. In order to conduct better research, various institutions or individuals begin to share their own data. However, data sharing between different organizations is affected by many factors, especially data security issues. At the moment, there is no scheme that has been commonly recognized to solve the problem of ecological data sharing. To provide a secure data sharing way for ecological research, a certificateless multireceiver signcryption scheme is proposed. In this paper, the proposed scheme can solve the key escrow problem, and it can improve efficiency on the basis of ensuring security by adopting elliptic curve cryptography (ECC). A rigorous security analysis proves that the scheme can resist various security attacks and ensure privacy protection based on a random oracle model. Performance analysis also shows that this scheme has the advantage of computational overhead compared to the same type of scheme. Therefore, the scheme is very suitable for the safe sharing of ecological data.

“…Their scheme provides authentication function for the receivers, but it uses too many bilinear parings operations, resulting in its low efficiency. In 2016, to perfect privacy protection mechanism, Pang et al [24] proposed a completely anonymous IBMS scheme, which offers both receiver anonymity and sender anonymity.…”

The certificateless multi-receiver signcryption scheme provides the sender with the ability to send the same message to multiple authorized receivers contemporaneously, and at the same time, it can avoid the key escrow problem in the existing identity-based multi-receiver signcryption schemes, which makes it to get great attention in the field of one-to-many communication. However, in the existing certificateless multi-receiver signcryption schemes, a secure channel is essential for their key extract algorithm, which brings some troubles in practical applications. On one hand, the security of the partial private key depends on the secure channel. Once the secure channel is broken by an attacker, the user's partial private key may be leaked. On the other hand, maintaining the secure channel increases the economic cost and implementation complexity of the application systems. Motivated by these concerns, we propose a new anonymous certificateless multi-receiver signcryption scheme, in which the key generation center only utilizes a public channel to send the pseudo partial private key to the user during the key extract algorithm, and the designated user can work out the real partial private key from the pseudo partial private key while others cannot. The avoidance of the secure channel improves the security of the proposed scheme and makes the communication system much lighter.
