Enhancement the reliability of communications in Multicast networks using RE-KEYING encryption keys

الملخص EN

With the increasing demand for communications in Multicast networks and the rapid and changing evolution of these networks, it has been necessary to achieve high reliability of these connections, meaning that the members authorized to use this service are only able to access any content related to the communications of this group Therefore, the best solution was to encrypt the group broadcast data from the sender with the shared group key with all authorized members so that symmetric encryption prevents other users from accessing the content to achieve this goal, a technique called RE-KEYING was used in the research.

This is done after each user has joined the group to prevent him from obtaining old information and after each user's departure to prevent him from accessing future information.

This research contributes to the development of the technique of using RE-KEYING encryption technology to ensure and improve the reliability of communications in multicast networks and to show how to distribute and exchange the key among the members of the group and then to indicate the meaning of confidentiality and reliability in these networks
