Data protection transmission method of P2P network

Abstract

The present invention discloses a data protection transmission method for peer-to-peer network. The method has an encryption server arranged in a peer-to-peer network, and comprises following the steps that: A. a data publication party sends data needing to be published to the encryption server; B. the encryption server encrypts the data needing to be published, saves a corresponding key and returns the encrypted data to the data publication party; C. the data publication party publishes the encrypted data in different pieces; D. a data request client collects the published encrypted data pieces through the peer-to-peer network; the data request client acquires the corresponding key from the encryption server and decrypts the collected encrypted data pieces according to the key. The present invention can be applicable to the characteristics of the peer-to-peer network, improve the data transmission security of the peer-to-peer network, prevent hackers from attacking the peer-to-peer network data and guarantee the rights and benefits of data owners and users.

Description

technical field [0001] The present invention relates to encryption technology of data communication, in particular to a data protection transmission method of point-to-point (P2P) network. Background technique [0002] At present, with the development of broadband Internet technology, point-to-point transmission technology is more and more widely used due to its low cost, strong network connectivity and high scalability. In such a distributed network, network participants share hardware and network resources, and they are both resource providers and resource acquirers. In this way, it not only solves the problem of excessive dependence on servers in the original client / server network architecture. In addition, it also enriches the program source, allowing users to have more choices. [0003] However, due to the characteristics of peer-to-peer networks, the security of data transmitted on peer-to-peer networks is relatively low, which makes peer-to-peer networks very vulnera...

Problems solved by technology

But for P2P networks, the file receiving end not only obtains file slices from the seed server or file server, but more importantly, it can also obtain file slices from other online clients, that is to say, the URL of the file slice is not fixed on the seed server or file server. However, it changes dynamically with the change of the shared client. Therefore, the above-mentioned processing solution in the prior art can only be applied to the file download method of the client / server in essence, and is not suitable for the file transfer method of the P2P network.
