The embodiment of the present application provides a kind of
data processing method and device, the method comprises: when receiving the connection request sent by mobile terminal, split equipment generates a random number, and the random number and the serial number of split equipment itself are sent to
server by mobile terminal;Wherein,
server is used to obtain the key information corresponding to serial number, and using key information, the first information digest is obtained by signing
processing to random number;When receiving the first information digest sent by
server through mobile terminal, the key information stored locally in split equipment is used to sign and process random number, and the second information digest is obtained;Check first information digest and second information digest, and in the case where first information digest and second information digest pass the check, open the
functional module in split equipment, to show the
IPTV application data obtained from mobile terminal, the security control to split equipment is realized, and the security is improved.
