Privacy Protection in Smart Cities by a Personal Data Management Protocol in Blockchain

Due to the increase of cybercrime and security risks in computer networks as well as violations of user privacy, it is essential to upgrade the existing protection models and provide practical solutions to meet these challenges. An example of these risks is the presence of a third party between users and various services, which leads to the collection and control of large amounts of users' personal information and the possibility of their databases being misused or hacked. Blockchain technology and encrypted currencies have so far shown that a decentralized network of peer-to-peer users, along with a general ledger, can do reliable computing. So, in this article, we are going to introduce a protocol that converts the blockchain network to an automated access control manager without the presence of a third party. To this end, we designed a mutual authentication protocol to create a secure channel between the user and the service and then demonstrate its accuracy and completeness using the Gong-Nidham-Yahalom belief logic [1]. The results of our evaluations show that our proposed protocol is secure enough to be used on the blockchain network and attackers are unable to penetrate, track, impersonate, inject, misrepresent or distort information using the common attacks.

Proposing a Method for Enhancing the Reliability of RPL Routing Protocol in the Smart Grid Neighborhood Area Networks

The RPL routing protocol is one of the most prominent protocols for low-power wireless networks. It has many benefits, including high flexibility and compatibility with different topologies, quality assurance, automatic configuration, self-healing, avoiding the creation of tree loops, and independence and transparency. Since the RPL's capability to meet the reliability requirements has not been sufficiently investigated and there is not much research about the reliability of this protocol, the purpose of this study is to propose a method for enhancing the reliability of RPL routing protocol in the Smart Grid Neighborhood Area Networks (NAN). We propose three methods for increasing the reliability of the RPL protocol: addition of cache at each node, considering two parents for each node and finally the combination of the two mentioned methods. The type of research is descriptive-analytic. Simulations have been performed in OPNET simulator. The results of this study indicate that the proposed methods significantly increase the reliability of this routing protocol in Smart Grid NAN.

Improving the AODV Protocol to Satisfy the Required Level of Reliability for Home Area Networks

For decades, the structure of existing power grids has not changed. It is an old structure that depends heavily on fossil fuel as an energy source, and in the future, this is likely to be critical in the field of energy. To solve these problems and to make optimal use of energy resources, a new concept is proposed, called Smart Grid. Smart Grid is an electric power distribution automation system, which can provide a two-way flow of electricity and information between power plants and consumers. The Smart Grid communications infrastructure consists of different network components, such as Home Area Network (HAN), Neighborhood Area Network (NAN) and Wide Area Network (WAN). Achieving the required level of reliability in the transmission of information to all sections, including the HAN, is one of the main objectives in the design and implementation of Smart Grid. This study offers a routing protocol by considering the parameters and constraints of HAN, which, by improving AODV routing protocol, achieves the level of required reliability for data transmission in this network. These improvements include: making table-driven AODV routing protocol, extending the routing protocol to compute multiple paths in a route discovery, simplification and providing the effect of HAN parameters. The results of the NS2 simulation indicate that applying this improved routing protocol in the HAN, satisfies the required level of reliability of the network, which is over 98%.
