Cryptography helps solve many computer and communication problems, including clock synchronization, where a group of nodes wants to agree on a theoretically unique clock in the system with the presence of malicious nodes trying to prevent the process of convergence; so we will need a set of mechanisms, including encryption. Many synchronization techniques suffer from high power consumption or vulnerability to attack or difficulty of implementation. In this article, we propose a synchronization protocol that contains two parts. The first part uses a lightweight linear scheme to encrypt clock messages to fend off certain types of attacks such as message manipulation. This scheme is suitable for Wireless sensor networks (WSNs) with negligible encryption and decryption time. The second part is the process of calculating the clock based on a very simple consensus algorithm. The study of the proposed protocol has shown very satisfactory results.

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.

Nowadays, cloud computing offers a digital infrastructure for smart city development. Cognitive cities are steadily automating daily urban processes. The ever expanding objective-driven communities gather and share sensitive data that must be stored securely. Cloud computing offers a suitable platform that allows cognitive smart cities to access and re-access data to learn from their past to adapt its current behaviour. However, the cloud is an untrusted entity that may expose data when decrypted for processing by systems. In this paper, we treat the issue of encrypted data processing. Often, the data is encrypted prior to transferring it to the cloud, where the cloud must have the data in clear to be able to make calculations which raises security and privacy threats if the cloud is considered untrusted. The scenario of asking users to make the calculations after decrypting the received cloud data and encrypting the obtained results before sending them back to the cloud is not a practical solution in distributed multi-tenant architectures. Homomorphic encryption allows offers a solution for processing encrypted data. Many existing homomorphic encryption schemes suffer from limitations that hinder their usability. This paper presents an efficient fully homomorphic encryption scheme using twin key encryption and magic number fragmentation. The details of the scheme are presented along with cryptanalytic attacks to assess its effectiveness. The proposed scheme exhibits strong resilience against brute-force attacks compared to its rivals from the literature.Finally, we illustrate the applicability of the proposed scheme using a cognitive smart city application.
