Description
Technical Field
The present invention relates to the field of media services and network security, and in particular, to a system and method for guaranteeing security attributes of media services.
Background
With the continuous development of media video services, users have put new demands on watching videos. The IPTV (interactive network television) soft terminal gets rid of the limitation of the traditional set-top box hardware, and the IPTV can be watched only by installing the IPTV soft terminal application in an intelligent terminal (such as a television). The intelligent terminal can also install various OTT (Internet video) applications as required, and the user can select the applications as required to watch, so that the experience is greatly improved.
Fig. 1 shows a schematic diagram of a network environment including an IPTV service in the prior art. Due to the requirement of broadcast control, the related information of IPTV service media needs to be transmitted in the B plane network of the private network, while other OTT services are transmitted in the a plane of the public network (the dotted line is only used to divide the public network and the private network in the figure for illustration). When a user initiates an IPTV soft terminal application or OTT application viewing request, the intelligent selection of a public network and a private network is carried out through the home gateway according to the destination 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 obtain the address of an IPTV service platform server in a private network environment in a simple mode of packet capturing, log viewing and the like for the IPTV soft terminal, and because the existing home gateway only distinguishes the attributes of a private network and a public network of a service according to the IP routing information of a service purpose and does not perform safety control on a terminal hung down, the illegal user can easily access a private network B plane by using the terminal to initiate attack on the IPTV service platform server in the private network, so that the service use of the IPTV soft terminal is influenced, and the network safety problem is caused. In order to prevent an illegal terminal from accessing a private network B plane network, a common method is to directly transmit a unique characteristic identifier of a legal terminal into a home gateway, and the home gateway performs terminal validity check according to the characteristic, but the method leaves a security hole.
Therefore, there is a need for a method and a system capable of guaranteeing service security attributes of an IPTV soft terminal, so as to prevent a user from adding an illegal terminal in a home gateway in a private manner, and even if the illegal terminal is added, the home gateway cannot acquire IP routing information of an IPTV service destination, and further cannot forward an attack request to a private network B plane network, thereby ensuring that the service of the IPTV soft terminal is not utilized by the illegal user, preventing the private network B plane network from being attacked, and controlling each terminal applying for accessing the private network B plane in real time, and guaranteeing network and service security of an IPTV service platform.
Disclosure of Invention
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter; nor is it intended to be used as an aid in determining or limiting the scope of the claimed subject matter.
At present, in order to prevent an illegal terminal from accessing a private network B plane network, a unique characteristic identifier of a legal terminal is directly transmitted into a home gateway, and the home gateway performs terminal validity check according to the characteristic, but the method still has security loopholes.
The invention adds a terminal legal check module in a home gateway, receives a secret key required to be issued by an IPTV service management platform, issues the IP routing information of the IPTV target by the gateway management platform with a trigger condition, and issues an encrypted terminal unique characteristic identifier.
According to the invention, when a user opens the IPTV soft terminal service, the IPTV service platform receives the unique characteristic identifier of the terminal and service information (such as user related information), after the IPTV service platform verifies that the service information is a user who legally opens the service, the unique characteristic identifier information of the legal terminal is sent to the gateway management platform, the gateway management platform encrypts the unique characteristic identifier of the terminal and then sends the encrypted unique characteristic identifier to the home gateway of the user, and simultaneously triggers the IPTV service routing information stored in the gateway management platform to be sent to the home gateway. And the IPTV service platform issues the secret key to the home gateway. The home gateway decrypts the encrypted terminal unique characteristic identifier by using the secret key to obtain a legal terminal unique characteristic identifier. When a user applies a terminal to use the IPTV soft terminal service, the home gateway judges whether the terminal belongs to a private network (B plane) service request according to IPTV service routing information, if so, the legality of the application terminal is verified according to the decrypted terminal unique characteristic identifier, namely whether the application terminal and the user open the IPTV soft terminal service, and the service application can be forwarded to a private network B plane network after the application terminal and the user pass the IPTV soft terminal service.
The invention discloses a method for guaranteeing media service security attributes, which comprises the following steps:
sending the unique characteristic identifier of the terminal and the service information to an IPTV service platform;

Detailed Description
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which specific embodiments of the invention are shown. Various advantages and benefits of the present invention will become apparent to those of ordinary skill in the art upon reading the following detailed description of the specific embodiments. It should be understood, however, that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. The following embodiments are provided so that the invention may be more fully understood. Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by those of skill in the art to which this application belongs.
Fig. 2 is a flowchart of a method for guaranteeing service security attributes of an IPTV soft terminal according to the present invention.
In step S210: when the television is provided with the soft terminal application, other management platforms transmit the unique terminal characteristic identification and service information (user related information) to the IPTV service platform;
in step S220: the IPTV service platform determines that the IPTV service platform is a legal user for opening the IPTV service by verifying the service information, and sends the unique characteristic identifier of the legal terminal of the user to the gateway management platform;
in step S230: the gateway management platform encrypts the received legal terminal unique characteristic identifier of the user and then sends the encrypted terminal unique characteristic identifier to the home gateway;
in step S240: and the gateway management platform triggers the operation of sending the IPTV service routing information stored in the gateway management platform to the home gateway.
Since sending the IPTV service routing information to the home gateway requires sending the encrypted terminal unique characteristic identifier to the home gateway as a trigger condition by the gateway management platform, it is ensured that the home gateway cannot directly obtain the IPTV service routing information, and an illegal terminal cannot access a private network B plane by using the IPTV service routing information through the home gateway, which can further guarantee the security of a private network B plane network;
at 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 characteristic identifier received from the gateway management platform by using a secret key received from the IPTV service platform, and obtains a legal terminal unique characteristic identifier. This shows that the home gateway using the present invention can judge the validity of the terminal applying for the IPTV service, so that an illegal user cannot add any illegal terminal identification to the home gateway by himself;
in step S270: a user applies for IPTV service and sends the IPTV service to a home gateway through a terminal;
in step S280: the home gateway judges the service attribute according to the routing information, after the service belongs to the private network IPTV service, the validity of the terminal unique feature identifier is checked, and after the validity is passed, the application can be transferred to a private network B plane network and sent to an IPTV service platform, otherwise, the service access request is rejected;
in step S290: the IPTV service platform receiving the request sends the service flow to the home gateway, and then further transmits the service flow to a legal terminal which puts forward an application, namely an IPTV soft terminal installed 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 invention.
The system of the present invention comprises: a terminal validity checking module 310 and a storage module 350 located at the home gateway, a terminal identification verifying module 330 and a key generating module 340 located at the IPTV service platform, and a gateway management platform 320.
The terminal identifier verification module 330 is communicatively connected to the gateway management platform 320, receives the terminal unique feature identifier and the service information from other platforms, verifies the service information, and sends the legal terminal unique feature identifier of the user to the gateway management platform 320 after determining that the user is a legal user for activating the IPTV service;
the gateway management platform 320 is communicatively connected to the terminal validity check module 310 and the storage module 350 at the home gateway, encrypts the received terminal-validity unique identifier of the user, and then issues the encrypted terminal-validity unique identifier to the terminal validity check module 310, and triggers issuing of the IPTV service routing information to the storage module 350.
The key generation module 340 at the IPTV service platform is communicatively connected with 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 check module 310 decrypts the encrypted terminal unique identifier received from the gateway management platform 320 by using the key received from the key generation module 340, so as to obtain a valid terminal unique identifier.
When a user sends a service access request to the home gateway through an application terminal, the home gateway judges the service attribute according to the routing information, and after the service belongs to a private network IPTV service, the terminal validity check module 310 checks the validity of the unique characteristic identifier of the terminal, and after the terminal passes the validity check, the application can be transferred to a private network B plane network and sent to an IPTV service platform, otherwise, the service access request is rejected.
According to the method, the verification of the user service information is added, and the illegal user cannot directly input the illegal terminal identification into the home gateway through measures of issuing the secret key to the home gateway, encrypting the unique terminal characteristic identification and then issuing the encrypted unique terminal characteristic identification to the home gateway of the user and the like. In addition, only when the encrypted terminal unique characteristic identifier is issued, the gateway management platform is triggered to issue IPTV service routing information, and the safety of IPTV private network services is guaranteed through a dual mechanism, so that an illegal user cannot access the IPTV service platform through an illegal terminal.
The above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present disclosure, and the present disclosure should be construed as being covered by the claims and the specification.
