Problems solved by technology

[0005] Since the AKA mechanism fails to solve the problem of obtaining the corresponding IMPI according to the IMSI sent by the terminal, it cannot be effectively applied to the user password negotiation process between the terminal using the SIM card or USIM card and the mobile communication network in the mobile broadcast TV service
In addition, the five-element authentication tuple operation in the key negotiation process in the prior art does not support terminals using SIM cards
