Abstract

This invention relates to a method for resource encryption and decryption for resource encryption in a distributed peer- to-peer (P2P) network, the distributed P2P network including at least one peer and at least one Central Service Unit. The encryption process comprises first the peer encrypting an original resource on said peer for the first time, then the encrypted resource is sliced, and the slices are encrypted for the second time. The decryption process comprises first a peer decrypting at least one encrypted slice which is received by said peer for the first time; then the decrypted slices are assembled and the peer decrypts said assembled resource for the second time. This invention can solve the problems associated with the copyright of the originator and the problems of rewards of the resource originator, promoter, uploader and service provider. Furthermore, it can prevent safety problems emerging during transaction processes, such as spoofing, personating, etc.
