Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of network data transmission technology.
Background technology
Internet, applications is the product of information age.Progressively flourishing along with network infrastructure particularly, the becoming increasingly abundant of network application, people's life more and more be unable to do without the Internet.The correct enforcement of internet, applications and correctly representing to the end user depends on the correctness and the reliability of network data transmission.
At inventionthe open systems interconnection reference model (OSI/RM, Open System InterconnectionReference Model) in, TCP/IP network protocol layer (TCP/IP, Transmission ControlProtocol/Internet Protocol) is the data transfer layer that is under the network application layer.When between the different user during mutual data transmission, as the user 1 of transmitting terminal network application layer, application data is bundled in the packet at osi model, be transferred to the TCP/IP network protocol layer; The TCP/IP network protocol layer is transferred to the TCP/IP network protocol layer of user's 2 correspondences of receiving terminal with packet by network medium, offers the network application layer on it again, and user 2 network application layer is responsible for using and represent data.
Transmission Control Protocol can only guarantee that receiving terminal can receive institute's data packets for transmission, but can't guarantee data safety of transmission in network, as is subjected to the interference of computer virus, is subjected to that the undesirable intercepts mala fide, interrupts, distorts, forgery etc.
For fail safe and the reliability that improves network data transmission, industry has proposed data encryption and decryption technology, will information encrypted encrypt, form ciphertext and in network, transmit, decode to receiving data according to identifying code at receiving terminal through cryptographic algorithm and encryption key.This technology has suitably remedied the safety issue of network protocol layer TCP/IP, but its encrypted authentication data are to be embedded into application data inside, if in network, be subjected to malicious attack through ciphered data, can not correctly transmit reliably, then the data that get access to of application layer still can't be used.
In order to overcome the problem that exists in digital encryption and the decryption technology, industry proposed again digital copyright protection technology (DRM, Digital Rights Management) and digital watermark technology (DW, DigitalWatermark).The DRM technology is in the technical further reinforcement checking user of encryption and decryption qualified use data whether.After this technology is encrypted digital content; mainly emphasize to have only authorized user just can obtain decruption key, and decruption key is that encryption technology adds the hardware binding technology with the binding of user's hardware information; prevented illegal copies, this technology can reach the purpose of copyright protection effectively.The DW technology is at the inner embed watermark information of Applied Digital, proves the source of application data.This watermark information is normally sightless, has only the testing tool by special use to extract.The DW technology can be used for the copyright protection of picture, music or film; substantially do not damaging under the situation of original works quality; the mode of the relevant information of copyright, be hidden in picture, music or the film, and vision or the sense of hearing of the variation that produces by the people can't find with watermark.
Above-mentioned DRM technology and DW technology are with respect to common digital encryption decryption technology, prevented that Applied Digital is by bootlegging or illegal the use, improved safety of data, but these two kinds of technology are very complicated and expensive in realization, too poor for common network data transmission feasibility, and because these two kinds of technology guarantee that just data are not illegally usurped, and intercepted can not avoid data in network, to transmit the time, interrupted, distorted, forgery etc., so still can't guarantee application data correctly transmission reliably in network.
