Problems solved by technology

[0006] In the above solutions, multiple clients download encrypted ciphertext from the same server, and the chances of downloading ciphertext at the same time are very high, and the possibility of network and server congestion is very high. The authenticity of the lack of verification means, it is easy to cause the document to be forged and tampered, and the security is low

Embodiment 1

[0061]This specific embodiment provides a method for encrypting and publishing Internet content, which uses the publishing server to divide the file F containing the content to be published into segmented plaintexts in a certain way, and then encrypts each segmented plaintext with different passwords to generate segments ciphertext, and then encapsulate the control segment and each subsection ciphertext into file X and publish it to the download server for the client to download; afterward, the client requests the publishing server to return the password for decrypting each subsection ciphertext in the file X, and the subsection The ciphertext is decrypted to obtain segmented plaintext, and each segmented plaintext is reassembled to obtain file F.

[0062] Specifically, as figure 1 As shown, the specific steps of a kind of Internet content encryption release method of this specific embodiment include:

[0063] S101: The publishing server divides the original file containing t...

Embodiment 2

[0099] Such as image 3 As shown, it is a structure diagram of an Internet content encryption publishing system in this specific embodiment, the system includes a server subsystem and a client subsystem communicating through the Internet, the server subsystem includes a publishing server and at least one download server, and the client There is a client on the terminal system;

[0100] Publishers include:

[0101] The segmentation module is used to divide the original file containing the content to be released into several segmented plaintexts, and generate a control segment containing segment control information; wherein, the segment control information includes the segment number, segment size, Encryption algorithm, decryption conditions. The segmented plaintext can be segmented in a certain way, for example, the segmenting rules can be preset in the segmenting module, and segmented according to a certain size or video time.

[0102] The encryption module is used to encry...

Abstract

The invention relates to a webpage?offline?browsing field, and particularly relates to an Internet content?encryption release method and a system. The method comprises steps of dividing an original file containing to-be-released content into a plurality of plaintext segments by a release server and generating control segments containing segment control information, carrying out encryption on each plaintext segment according to the control segment by the release server to generate ciphertext segments, packaging the control segment and each ciphertext segment by the release server to form a new file, releasing the new file to at least one downloading server for downloading by a client by the release server, downing the new file form the downloading server by the client, sending a decryption?request to the release server by the client, acquiring a corresponding decryption?password according to the decryption?request and sending the decryption?password to the client by the release server, and receiving the decryption?password by the client, using the decryption?password to carry out decryption?processing on each ciphertext segment and recombining each plaintext segment to generate an original file. According to the method and the system, network and server load when the file is released can be effectively reduced.

Description

technical field [0001] The present invention relates to the field of offline browsing of webpages, and more particularly relates to a method and system for encrypting and publishing Internet content. Background technique [0002] When a file containing massive data (such as a video) is published over the Internet, multiple clients may communicate with the server at the same time to obtain the file, which will easily form a peak of access to the file, resulting in network and server congestion. The invention adopts encryption technology to encrypt a file, and then publishes the cipher text of the file for downloading in advance, so as to avoid the above-mentioned congestion problem caused when the file is released. For encrypted downloading of files, the prior art provides various solutions. [0003] For example, one solution is to divide the media content into segments on the server side (encryption side), and add content encryption and decryption keys to the headers of all...
