Analysis and Evaluation of Security and Privacy in Mobile Social Networks

The revolution in the two dimensions of information and communication has changed and transformed various aspects of human life. In other words, the behaviors and interactions of individuals have been greatly affected by the changes and transformations in the two aforementioned dimensions. The emergence of new technologies in both dimensions has provided very powerful platforms and tools for the formation of thoughts and communication between different people from different places. In line with these remarkable developments, everyone has been able to provide a lot of new information in various ways and in a wide range of dimensions and scope to a wide range of their fellow human beings. One of the most important communication and information tools between individual humans is mobile phones, especially smart phones. Also, the expansion of social networks in the Internet space, which is actually considered one of the foundations of the new revolution, has provided a very powerful and suitable platform for exchanging information and communicating between different people. Mobile social networks are a comprehensive software platform and a cyberspace in which smartphones that are physically close to each other can create a wireless network. So that people can easily carry out a dating process in public spaces such as airports, coffee shops, and theaters by sharing their interests with those who are nearby. With this development and increased use, there is still a concern in the hearts of people. Given that a lot of information and data is stored and shared in people's personal profiles, the most important issue in such situations is security and personalization. In this study, an attempt has been made to introduce and fully investigate a secure dating protocol in mobile social networks. The present study, focusing on a model of a secure dating process in mobile social networks, examines its impact on social networks and analyzes existing problems. So that by using this profile protocol, users are able to communicate with each other without being fully familiar with each other's complete personal details. In the following, to improve the execution time of the protocol, a high-performance encryption algorithm is used and it is shown that by applying this algorithm and the possibility of using a long-length encryption key while maintaining efficiency, the security of the protocol is significantly increased. The results of the implementation and experiments as well as the evaluations indicate that the efficiency of the proposed protocol in terms of execution time has been significantly improved.
