Description
Technical field
The invention belongs to field of information security technology, a kind of method for relating in particular to secure transmission web information.
Background technique
With scientific and technological progress and economic development, personal information security and personal secrets are increasingly valued by people, special
It is not the increase with mobile device, the storage information and transmission information of mobile device will be to letters if taking no action to protect
Cease the great hidden danger of safety belt.
In recent years, with the raising that people's security protection is realized, intelligent video camera head has become the " mark of more and more families
With ".Wi-Fi is connected, even if being away from home situation about can also constantly monitor in family.It is reported that wired home camera is from biography
The industrial security monitoring camera of system is evolved, it has many joyful novel capabilities, and ordinary family user is suitble to use.
At the same time, because design production and the relevant enterprise promoted are many and diverse, brand is numerous, lacks unified safety standard, some products
Lack perfect safety-related design, therefore is easy to be controlled by hacker.The intelligent video camera head product of current list marketing at home
There are many board, find after tested, and there are user informations to reveal for nearly eighty per cant product, data transmit unencryption, the non-security hardening of APP, generation
Code be logically present defect, hardware there are debugging interface, can the safety defects such as crosswise joint.The presence of these safety defects allows access
The intelligent video camera head of network can be controlled by criminal easily, transfer image and voice information at any time, to installation camera
Family or company are monitored even live on line.That is, the family " small bodyguard " of user installation, it is more likely that become and steal
Take " seed-sowing machine " of privacy.
Also, with the continuous development of artificial intelligence technology, the following wisdom mobile phone will really become depositing as a house keeper
?.However, this also bring it is many about privacy the problem of, the core of artificial intelligence is to learn after all, knows that user is every
What the state at a moment, wherein done.For a user, these belong to privacy.How to guarantee that privacy of user is not let out
The case where dew, goes down the realization of assurance function, is the problem of having to thinking.In addition, individual goes on business, need to transmit file, uses
File encryption mode is transmitted both troublesome or dangerous.Far-end video and household chat, individual privacy be also easily intercepted and
Exposure.Therefore, Information of Development safe practice is very urgent.
The prior art that Chinese patent notification number is CN101388764B discloses a kind of data letter on March 18th, 2009
Guard method, system and the encryption device of breath are used for the storage, transmission or exchange process of data, wherein method includes：?
Data, which provide, is arranged encryption device on the data transfer path between end and data receiver, and the encryption device is described in process
The transmission data of transmission path are encrypted, and it is described transmission data in be added the receiving end identity information generate with
The corresponding reception end data in the receiving end, to the operation for receiving end data all must through the certification of the encryption device, and
And the identity information of the receiving end is all shown in the illegal or unauthorized operating process for receiving end data.This is specially
Benefit can reduce data letter while the copyright of effective protection data information on the circulations such as data information transfer and exchange
The circulation cost of breath, and the right-safeguarding evidence of copyright protection can be provided.But in terms of the patent is mainly used in intellectual property protection,
Its narrow scope of application.It is connect by network interface with encryption device in addition, the data in the patent provide end, encryption device passes through again
Network interface is connect with data receiver, and data provide the data that end is sent and enter data receiver by encryption device, and data connect
Receiving end to solve data then must online under decrypted using encryption device, there is decryption complex procedures defect, Wu Fashi
Shi Xiemi.Therefore teleconference, the real-time enciphering/deciphering of needs such as network monitoring and the encryption of home cinema head be can not be applied to
Place, can not be with the timely enciphering/deciphering application scenarios of third party software such as QQ, wechat and network payment etc..And the patent
Can only point-to-point coded communication, be unable to multimachine while communicating.
Summary of the invention
It is an object of the invention to solve the above-mentioned problems in the prior art, a kind of secure transmission web information is provided
Method, the present invention needs the network information transmitted to encrypt at communication line both ends, makes letter by the way of end-to-end encryption
Breath is sent to another user terminal by a user terminal in an encrypted form, and two users end is decrypted using dynamic encryption keys,
Can effectively prevent the attack of network uplink and interchanger so that the transmission of the network information can reach attack not into, take
