Method and system for transmitting and enciphering medium based on P2P network

Abstract

The invention is suitable for the network communication field, and provides a media encryption method based on a P2P network media transmission and a system. The media encryption method comprises the steps as follows: the amount of a media data block sent to a media requesting client each time is set by a media source client, and the amount is greater than or equals to two; the position number of an encryption media data block in the media data block with the amount is set by the media source client; and the media source client extracts the encryption media data block according to the position number, and encrypts a plurality of the media data blocks with the amount. The method and the system transmit a plurality of data blocks to the media requesting client once through the media source client, and increases the media transmitting speed; at the same time, the method and the system adopt the encryption and decryption manner that one media data block encrypts a plurality of the media data blocks, so that the security for media data transmission is ensured; the real-time charging function can be served when needing to obtaining media charging from a user; and the acquiring frequency of a server on the charging information is reduced at the same time.

Description

technical field [0001] The invention belongs to the field of network communication, and in particular relates to a method for network media transmission based on a point-to-point technology (Peer-to-Peer, P2P), a method and a system for media encryption. Background technique [0002] In the field of network communication, the text, graphics, sounds, images, animations, etc. of information can be called media. Since the birth of the Internet, it has attracted a large number of Internet users with its free, shared and open characteristics, and has become an important channel for people to obtain media information. Ordinary Internet users can publish content on the Internet and truly integrate into it. Today, when the Internet is dominant, the Internet provides users with a service platform for sharing media information. Users can publish media information to the network, or download shared resource information through the network. [0003] The emergence of P2P technology pr...
