Benefits of technology

The technology described in this patented allows for securely delivering multimedia files over networks like DSL or cable TV without compromising their security measures such as encryption key management techniques. It also ensures users are only able access specific parts of these documents while still keeping them private. Additionally, it supports quicker-forward feature on mobile devices with faster speed capabilities than traditional methods.

Problems solved by technology

Technological Problem addressed in this patents relating to improving Content Delivery Service Protocol Overall, existing methods such as CDN require significant amounts of storage space and communication capabilities while also being vulnerable to attacks caused by hackers.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with drawings and embodiments.

[0024] figure 1 A flow chart of a media content transmission method based on a CDN and P2P fusion framework provided by a specific embodiment of the present invention. Such as figure 1 As shown, the method includes the following steps:

[0025] S1: The source server uploads the media content stored on it to each CDN network node;

[0026] Wherein, the media content stored on the source server can be uploaded to each CDN network node in an encrypted or unencrypted manner.

[0027] When the media content is uploaded in an encrypted manner, the privacy and security of the media content can be more effectively guaranteed. The source server encrypts the media content stored on it with a symmetric key and uploads it to each CDN network node. The symmetric key is determined through negotiation between the source server and the CDN network node.

[0028] S2: Each CDN netwo...

Abstract

The invention discloses a method and a system for media content transmission based on a CDN (Content Distribution Network) and P2P (Peer to Peer) converged infrastructure, belonging to the field of multimedia communication. The method comprises the steps: a source server uploads stored media contents to all CDN network nodes at first; all CDN network nodes segment received media contents and respectively sign and store the media content segments; the CDN network nodes extract the media content segments from the specific CDN network nodes according a content request of a user terminal and transmit the media content segments after the media content segments are fragmented; and the user terminal splices the received content fragments into a content segment and carries out signature verification on the CDN network nodes and the spliced media content segment through a CA (Certificate Authority) certificate chain. The method disclosed by the invention has the advantages of guaranteeing the content privacy in a transmission process and data completeness and preventing the contents from artificial manipulation and damage, and meanwhile, a segmented signature manner is favorable for reducing the quantity of fragments to be retransmitted when transmission errors occur, so that flow waste is reduced.
