“…Figure 1: Cloud security Indeed, public networks including distributed systems and cloud computing create security breaches also in terms of privacy and it is more manageable for an attacker to access data [1][2][3][4]. Similarly, the replacement of human beings by machines and programs makes relations much more anonymous even though access to this information requires strong authentication methods [5,6].…”

In recent years, Cloud Computing and Big Data have been considered the most attractive areas that are revolutionizing the IT world. Cloud Computing paradigm has recently appeared that allows running proprietary or difficult portable applications outside their original software environment on one or more virtual hardware platforms. Therefore, we are to developing such techniques which make it possible to secure communication between the communicating Cloud entities. These techniques must take into account several factors due to the data transmitted in this type of environment is proprietary and of significant size. Conventional data security techniques are not suitable for today's cloud usage. Hence, the main research of this thesis is to define an adaptable architecture with the aim to propose a scalable system that supports cloud services. We will define feasible security solutions dedicated to the Cloud computing context in order to robustly protect data stored in the Cloud. We are more precisely looking for working on NoSQL databases. We also intend to propose a secure solution based on the blockchain that has powerful features like decentralization, autonomy, security, reliability, and transparency.

.We aim to devise a technique to share k number of secret images to n number of participants with ( n ≥ k ) in such a way that only k or more participants can collaborate to get the original k secret images. The proposed approach relies on the development of a spanning tree from a complete graph G for the share image generation in which each of the k pixels retrieved from the k secret images is considered to be one of the k vertices of G. Each of the spanning trees of G is represented by a unique sequence of numbers known as Prufer sequences, and each participant is assigned a random Prufer sequence. The Prufer sequence of a participant is used to generate the share images for that participant. The share images are kept in a blockchain using interplanetary file system. This scheme is suitable for protecting sensitive images through distributed storage while eliminating the single points of failure. Because the blockchain is an immutable decentralized public record, anyone can verify their shares as well as the shares of other participants, thereby preventing cheating by any participant. The scheme presents a lossless reconstruction of k secret images, making it perfect for use in military applications, medical applications, and other applications in which lossless recovery is a crucial element. Extensive experimental analysis confirms that the proposed scheme is secure, cheat proof, and lossless.

“…After each agent announces its result N , the number N that gets a maximum of votes will be the number of participants. In the second step "creation of encrypted list", each agent A i generates a random and temporary number x i also a random and temporary secret key y i to encrypt x i using a symmetric scheme that based on key exchange protocol [29] according to the following equation:…”

Accord is an important operation in the mechanism design for multi-agent systems and consequently to applications built for these environments , such as ad hoc networks, virtual organizations, and decision-support tools for smart production systems. Much attention has been given to designing the process for resisting manipulation by strategic voting and decentralized control. The emphasis is on local decision-making based on locally available information and perception of events occurring locally. This manuscript presents a secure decision-support algorithm in a multi-agent system. The proposed consensus-based model serves multiple purposes in production planning and control, supply chain management , and product design and development. In particular, we describe decision-making, the selection of a leader, and the exploitation of limited resources. The importance of the proposal is to ensure robustness in a specific way; in which, decisions are carried out considering that the system is open, which means that the number of agents present is variable at each process. Our model is based on that a group of agents makes different decisions in a task, then the algorithm chooses one of these decisions logically, safe, efficient, and fast and stays away from emotional decisions even in dealing with the decisions of others that affect production.
