The sensor cloud is a new model of computing paradigm for Wireless Sensor Networks (WSNs), which facilitates resource sharing and provides a platform to integrate different sensor networks where multiple users can build their own sensing applications at the same time. It enables a multi-user on-demand sensory system, where computing, sensing, and wireless network resources are shared among applications. Therefore, it has inherent challenges for providing security and privacy across the sensor cloud infrastructure. With the integration of WSNs with different ownerships, and users running a variety of applications including their own code, there is a need for a risk assessment mechanism to estimate the likelihood and impact of attacks on the life of the network. The data being generated by the wireless sensors in a sensor cloud need to be protected against adversaries, which may be outsiders as well as insiders. Similarly, the code disseminated to the sensors within the sensor cloud needs to be protected against inside and outside adversaries. Moreover, since the wireless sensors cannot support complex and energy-intensive measures, the lightweight schemes for integrity, security, and privacy of the data have to be redesigned. The book starts with the motivation and architecture discussion of a sensor cloud. Due to the integration of multiple WSNs running user-owned applications and code, the possibility of attacks is more likely. Thus, next, we discuss a risk assessment mechanism to estimate the likelihood and impact of attacks on these WSNs in a sensor cloud using a framework that allows the security administrator to better understand the threats present and take necessary actions. Then, we discuss integrity and privacy preserving data aggregation in a sensor cloud as it becomes harder to protect data in this environment. Integrity of data can be compromised as it becomes easier for an attacker to inject false data in a sensor cloud, and due to hop by hop nature, privacy of data could be leaked as well. Next, the book discusses a fine-grained access control scheme which works on the secure aggregated data in a sensor cloud. This scheme uses Attribute Based Encryption (ABE) to achieve the objective. Furthermore, to securely and efficiently disseminate application code in sensor cloud, we present a secure code dissemination algorithm which first reduces the amount of code to be transmitted from the base station to the sensor nodes. It then uses Symmetric Proxy Re-encryption along with Bloom filters and Hash-based Message Authentication Code (HMACs) to protect the code against eavesdropping and false code injection attacks.

"Sensor Cloud is a new model of computing for Wireless Sensor Networks, which facilitates resource sharing and enables large scale sensor networks. A multi-user distributed system, however, where resources are shared, has inherent challenges in security and privacy. The data being generated by the wireless sensors in a sensor cloud need to be protected against adversaries, which may be outsiders as well as insiders. Similarly the code which is disseminated to the sensors by the sensor cloud needs to be protected against inside and outside adversaries. Moreover, since the wireless sensors cannot support complex, energy intensive measures, the security and privacy of the data and the code have to be attained by way of lightweight algorithms. In this work, we first present two data aggregation algorithms, one based on an Elliptic Curve Cryptosystem (ECC) and the other based on symmetric key system, which provide confidentiality and integrity of data against an outside adversary and privacy against an in network adversary. A fine grained access control scheme which works on the securely aggregated data is presented next. This scheme uses Attribute Based Encryption (ABE) to achieve this objective. Finally, to securely and efficiently disseminate code in the sensor cloud, we present a code dissemination algorithm which first reduces the amount of code to be transmitted from the base station. It then uses Symmetric Proxy Re-encryption along with Bloom filters and HMACs to protect the code against eavesdropping and false code injection attacks."--Abstract, page iv.

Sensor cloud is an integration of sensor networks with the cloud to offer a variety of services to the end-users. Applications of this architecture can be seen in various fields such as healthcare information systems, forest fire monitoring systems, smart city, and other Internet-of-Things (IoT) applications. This technology is based on sensor networks; so, energy efficiency becomes one of the prime concerns. The sensed data that are stored in the cloud for further processing in order to get some insights are crucial in many applications; so, security also becomes another important challenge. This motivated us to design some energy-efficient and secure algorithms for the sensor cloud. Security can be implemented in many ways viz., access control, outlier detection, and security against various attacks. In the thesis, we are targeting access control and outlier detection to implement security concerns. We designed one scheme for energy efficiency, one for access control, and two for outlier detection using different approaches. Chapter 3 proposes an energy efficient and fault tolerant scheme for sensor cloud. Wireless Sensor Networks (WSN) find several applications in hard-to-reach areas. As sensors have limited battery power, so, many energy-aware protocols based on negotiation, clustering, and agents have been developed to increase the lifetime of the network. This thesis finds limitations with some multi-agent-based protocols as they place the sink node at the center of the monitoring region which is quite difficult in hard-toreach areas. Therefore, a multi-agent-based energy and fault aware protocol for hard-toreach territories (MAHT) is proposed which uses the technique of Impact Factor to identify a central node with high power capability and dynamic itinerary planning is done to make the protocol fault-tolerant. Its agent migration technique results in improvement of energy efficiency, task completion time, and network lifetime. MAHT is simulated using Castalia simulator, and the impact of payload size, network size, node failures, etc on various performance metrics is analyzed. The proposed protocol outperforms the existing schemes viz., Tree Based Itinerary Design (TBID) and Multiple Mobile Agents with Dynamic Itineraries based Data Dissemination (MMADIDD).

This book documents the scientific results of the projects related to the Trusted Cloud Program, covering fundamental aspects of trust, security, and quality of service for cloud-based services and applications. These results aim to allow trustworthy IT applications in the cloud by providing a reliable and secure technical and legal framework. In this domain, business models, legislative circumstances, technical possibilities, and realizable security are closely interwoven and thus are addressed jointly. The book is organized in four parts on “Security and Privacy”, “Software Engineering and Software Quality”, “Platforms, Middleware and Integration”, and “Social Aspects, Business Models and Standards”. It thus provides a holistic view on technological, societal, and legal aspects, which are indispensable not only to ensure the security of cloud services and the data they process, but also to gain the trust of society, business, industry, and science in these services. The ultimate goal of the book, as well as of the Trusted Cloud Program in general, is to distribute these results to a broader audience in both academia and industry, and thus to help with the proliferation of "Industry 4.0" services.
