Entropy service for secure real‐time mission critical communications

Real Time Mission Critical Communication (RTMCC) in emergency situations can include real-time video and audio calls between peers first responders all occurring simultaneously. RTMCC also requires secure end-to-end (E2E) group communication (GC) sessions against potential security threats during such incidents. In this paper, we explore aspects of the possible methods that are suitable for a software implementation session key change GC E2E encryption RTMCC. Later, introduce our Entropy Service concept, which be very effective sessions. The proposed method ensures systems while allowing fast clients involved an with computational complexity
