Abstract
The invention relates to an information security technology and particularly relates to a secure digital certificate transmission method for a smart television. The method comprises the following main steps of: firstly creating a digital certificate at a network service terminal, and then transmitting the digital certificate to a DVB (Digital Video Broadcasting) video data stream broadcasting terminal through a dedicated channel; embedding the digital certificate into a video data stream of a source terminal, packaging the video data stream into a video data packet, and sending the video data packet to a client terminal; acquiring the video data packet by the client terminal through a DVB channel; and finally obtaining the digital certificate by parsing the video data packet, and carrying out security certification on the digital certificate. The digital certificate transmission method has the beneficial effects that the DVB channel can not be subjected to the threat of attacking, tampering and the like on the security of information transmission, and meanwhile, the DVB channel has the excellent characteristics of high bandwidth, large digital certificate transmission quantity and no occurrence of network congestion, so that the security certification can be effectively improved. The digital certificate transmission method is particularly applicable to the transmission and certification of the digital certificate.
Description
Technical field
The present invention relates to information security technology, relate to specifically a kind of safe transmission method of the digital certificate for intelligent television.
Background technology
In recent years, along with the development of embedded technology and embedded OS, intelligent television by network carry out surfing, click downloading contents, the electronic transaction of being correlated with become reality.At present how intelligent television faces aspect information security, better protects the problem of the terminals such as intelligent television of access network.The mode of the raising information security of main flow all is to adopt from the Internet relevant digital certificate of download to carry out safety certification at present, but there is a critical defect in this mode, that is: the Internet is owing to the opening of itself, and perhaps the digital certificate of transmission is just attacked, distorted in transmission course.Therefore rely on the Internet to provide the mode of digital certificate to have larger potential safety hazard, can not guarantee the fail safe of relevant information.
Summary of the invention
This reality invention technical problem to be solved is to propose exactly a kind of transmission method of digital certificate, the fail safe of raising digital certificate in transmission course, thereby raising information security.
The present invention solves the problems of the technologies described above the technical scheme that adopts: the transmission method of digital certificate, it is characterized in that, and may further comprise the steps:
A. network service end generating digital certificate;
B. by dedicated channel digital certificate is transferred to the video data stream initiator;
C. digital certificate is embedded in the video data stream of source, be packaged as video packets of data and send to client;
D. client terminal obtains video packets of data by digital video broadcast channels;
E. from video packets of data, parse digital certificate and carry out safety certification.
Concrete, described video data stream is for adopting the video data transmitting stream of MPEG-2TS standard.
Beneficial effect of the present invention is, the DVB(digital broadcasting) channel can be not under attack on information transmission security, the threat such as distort, the DVB channel also has the outstanding feature that bandwidth height, digital certificate transmission amount greatly, can not produce network congestion simultaneously, can the Effective Raise safety certification.
Description of drawings
Fig. 1 is the method flow diagram of embodiment.
Embodiment
Be described further below in conjunction with the method for drawings and Examples to invention:
The present invention proposes a kind of transmission method of digital certificate, and key step is: at first at network service end generating digital certificate, then by dedicated channel digital certificate is transferred to the video data stream initiator of DVB; Digital certificate is being embedded in the video data stream of source, be packaged as video packets of data and send to client; Client terminal obtains video packets of data by digital video broadcast channels; From video packets of data, parse at last digital certificate and carry out safety certification.
A kind of preferred scheme is that described video data stream is for adopting the video data transmitting stream of MPEG-2TS standard.
Embodiment:
As shown in Figure 1, this example is to download angry bird as example, and its concrete realization flow is:
At first produce " bird of indignation " digital certificate that this application program is relevant in service end; Then digital certificate is sent to the broadcasting center of digital TV video frequency channel by the channel of safety, present embodiment adopts the VPN technologies transmission to realize; Then in 188 byte TS broadcast data streams of standard, embed the digital certificate that sends over, the head that present embodiment wraps substantially in each 188 byte TS data embeds respectively 4 byte certificate data pieces, embed position and the not by force requirement of size of certificate, only require that terminal flows accordingly decoding and all can extract relevant certificate data; Be pushed to user side when TS flows by the digital television broadcasting net at last, Intelligent television terminal just can extract digital certificate by obtaining the TS packet, verifies.
