One of the most important technologies that has affected our lives today is cyberspace. On the other hand, one of the most important problems of social networks is the disclosure of users' information, i.e. the violation of their privacy. Therefore, protecting the privacy of users is very important, so the use of encryption methods is an important tool in ensuring the privacy and security of shared data users. The proposed framework of this paper is based on AES and RSA algorithms. This framework is designed to be decentralized and takes advantage of the AES and RSA algorithms to provide a framework that prevents unauthorized entities from accessing users' data and messages. Any safe method must be designed in such a way that there is no escape route for attackers and unauthorized entities. Therefore, our focus is on two important parts of secure methods, namely key management and privacy, which the results of this article show, the security assessment proved that our proposed framework is designed to be completely safe and correct, and increased security and efficiency. تفاصيل المقالة
