Determining a session encryption key during a session broadcast / multicast protocol using a secure real-time transport

摘要

A method of determining updated keys session encryption procedure laid characterized in that it comprises: providing a list of predetermined values; receive sequence numbers during a session; determine updated keys session encryption using a master key and index values ​​calculated using depaquete received sequence numbers and increasing values ​​contadorde loop counter had been set at a predetermined value from the list; and enmomentos desired, reset the increasing counter value of the loop counter to a next value predeterminadoproveniente list and continue to determine current session values ​​using yElements index calculated packages master key using the received sequence numbers and increasing losvalores of counter loop counter that have been reset to the next value in the list predeterminadoproveniente.
