Description
Technical Field
The application relates to the field of media service and network security, in particular to a system and a method for guaranteeing the security attribute of media service.
Background
With the continued development of media video services, users have placed new demands for viewing video. The IPTV (interactive network television) soft terminal gets rid of the limitation of the hardware of the traditional set-top box, and can watch IPTV only by installing the IPTV soft terminal application in the intelligent terminal (such as a television). The intelligent terminal can also install various OTT (Internet video) applications as required, and a user can select the applications to watch as required, so that experience is greatly improved.
Fig. 1 shows a schematic diagram of a network environment including an IPTV service in the prior art. Because of the requirement of broadcasting control, the related information of the IPTV service media needs to be transmitted in a private network B plane network, while other OTT services are transmitted in a public network A plane (the public network and the private network are divided by a dotted line in the figure to be only schematic). When a user initiates an IPTV soft terminal application or OTT application viewing request, intelligent selection of a public network and a private network is carried out through a home gateway according to target IP routing information, the IPTV service request initiated by the user is accessed to the private network, and other OTT services are accessed to the public network.
In actual use, an illegal user can acquire an IPTV service platform server address in a private network environment by simple modes of capturing packets of an IPTV soft terminal, checking logs and the like, and because the existing home gateway only distinguishes the private network and public network attributes of the service according to IP routing information of the service purpose, the illegal user can easily access a private network B plane by using the terminal without carrying out safety control on the underhung terminal, and attack on the IPTV service platform server in the private network is initiated, thereby influencing the service use of the IPTV soft terminal and causing network safety problems. In order to prevent an illegal terminal from accessing a private network B-plane network, the common practice is to directly transmit the unique characteristic identifier of a legal terminal into a home gateway, and the home gateway performs terminal validity verification according to the characteristic, but the method leaves a security hole.
Therefore, a method and a system for guaranteeing the service security attribute of the IPTV soft terminal are needed to prevent the user from adding an illegal terminal to the home gateway, and even if the illegal terminal is added, the home gateway cannot acquire the IP routing information of the IPTV service destination, and further cannot forward the attack request to the private network B-plane network, so as to ensure that the IPTV soft terminal service is not utilized by the illegal user, prevent the private network B-plane network from being attacked, and control each terminal applying to access the private network B-plane in real time, thereby guaranteeing the security of the IPTV service platform network and service.

Fig. 2 is a flowchart of a method of guaranteeing service security attributes of an IPTV soft terminal according to the present application.
In step S210: when the television is provided with a soft terminal application, other management platforms transmit the unique terminal characteristic identification and service information (user related information) to an IPTV service platform;
in step S220: the IPTV service platform determines that the IPTV service platform is a legal user for opening IPTV service through verifying service information, and sends a unique characteristic identifier of a legal terminal of the user to the gateway management platform;
in step S230: the gateway management platform encrypts the received unique characteristic identifier of the legal terminal of the user, and then transmits the encrypted unique characteristic identifier of the terminal to the home gateway;
in step S240: the gateway management platform triggers the operation of issuing the IPTV service routing information stored in the gateway management platform to the home gateway.
Because the IPTV service routing information is issued to the home gateway, the gateway management platform is required to issue the encrypted terminal unique characteristic identifier to the home gateway as a trigger condition, the home gateway is ensured not to directly obtain the IPTV service routing information, and the illegal terminal cannot access the private network B plane by using the IPTV service routing information through the home gateway, so that the network security of the private network B plane can be further ensured;
in step S250: the IPTV service platform issues the secret key to the home gateway;
in step S260: the home gateway stores IPTV service routing information, decrypts the encrypted terminal unique feature identifier received from the gateway management platform by using the key received from the IPTV service platform, and obtains a legal terminal unique feature identifier. The home gateway using the application can judge the legitimacy of the terminal applying IPTV service, so that an illegal user cannot add any illegal terminal identifier to the home gateway by himself;
in step S270: the user sends the IPTV service application to the home gateway through the terminal;
in step S280: the home gateway judges the service attribute according to the routing information, after belonging to the private network IPTV service, the home gateway performs the validity check of the unique terminal characteristic identification, and after passing, the home gateway can transfer the application to the private network B plane network to send to the IPTV service platform, otherwise, the home gateway refuses the service access request;
in step S290: and the IPTV service platform which receives the request transmits the service flow to the home gateway and then further transmits the service flow to a legal terminal which applies for, namely an IPTV soft terminal which is arranged in the intelligent television.
Fig. 3 is a block diagram of a system for guaranteeing service security attributes of an IPTV soft terminal according to the present application.
The system of the application comprises: a terminal validity verification module 310 and a storage module 350 located at the home gateway, a terminal identification verification module 330 and a key generation module 340 located at the IPTV service platform, and a gateway management platform 320.
The terminal identification verification module 330 is communicatively connected with the gateway management platform 320, receives the unique terminal characteristic identification and service information from other platforms, verifies the service information, and sends the unique terminal characteristic identification of the legal user who opens the IPTV service to the gateway management platform 320 after determining the legal user;
the gateway management platform 320 is communicatively connected with the terminal legal verification module 310 and the storage module 350 at the home gateway, encrypts the received legal terminal unique feature identifier of the user, then issues the encrypted terminal unique feature identifier to the terminal legal verification module 310, and triggers the IPTV service routing information to be issued to the storage module 350.
The key generation module 340 at the IPTV service platform is communicatively connected to the terminal validity check module 310 at the home gateway, and issues the generated key to the terminal validity check module 310;
the storage module 350 at the home gateway stores the IPTV service routing information from the gateway management platform 320, and the terminal validity verification module 310 decrypts the encrypted terminal unique feature identifier received from the gateway management platform 320 with the key received from the key generation module 340 to obtain a valid terminal unique feature identifier.
When a user sends a service access request to a home gateway through an application terminal, the home gateway judges service attributes according to route information, after belonging to a private network IPTV service, a terminal legal verification module 310 performs terminal unique feature identification validity verification, and after passing, the user can transfer the application to a private network B plane network to send the request to an IPTV service platform, otherwise, the service access request is refused.
According to the method, verification of the user service information is increased, and illegal users cannot directly input illegal terminal identifiers into the home gateway through measures such as issuing keys to the home gateway, encrypting terminal unique characteristic identifiers and then issuing the encrypted terminal unique characteristic identifiers to the home gateway of the user. In addition, only when the unique characteristic identifier of the encrypted terminal is issued, the gateway management platform is triggered to issue IPTV service routing information, and the dual mechanism guarantees the safety of IPTV private network service, so that an illegal user cannot access the IPTV service platform through the illegal terminal.
The above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application, and are intended to be included within the scope of the appended claims and description.
