Content distribution with mutual anonymity

摘要

A method for transferring content includes requesting the content from a serving peer and sending the content to a requesting peer. Requesting the content includes sending a request to a tracker, receiving a request token, a path identifier, and a first peer identifier from the tracker, and sending a request message to a second peer. The first peer identifier includes an identity of a first peer, and the request message includes the request token, the path identifier, and the first peer identifier. Sending the content includes receiving the request token and the path identifier from a third peer, sending a return message to a fourth peer, and transferring the content from the serving peer to the requesting peer through a transfer path. The return message includes the path identifier and a second peer identifier. The second peer identifier includes an identity of a fifth peer. The transfer path includes at least the second, fourth, and fifth peers.

主权项

1. A system for providing content distribution with mutual anonymity, the system comprising:
a memory that stores instructions; a processor that executes the instructions to perform operations, the operations comprising:
receiving a request token, a path identifier, and a landing point identifier from a tracker in response to the tracker receiving a request for contacting a serving peer, wherein the landing point identifier includes an identity of a first peer other than the serving peer within a serving peer tree, wherein the serving peer tree includes the serving peer, the first peer, a second peer, and a third peer;sending a request message and a signature message to a fourth peer within a requesting peer tree, wherein the requesting peer tree includes a requesting peer, the fourth peer, and a fifth peer, wherein the request message includes the request token, the path identifier, and the landing point identifier, wherein the requesting peer tree is different from the serving peer tree, wherein the signature message includes a random number of bits to prevent the fourth peer from determining an identity of the requesting peer;receiving the request token, the path identifier, and a jumping point identifier from the second peer, wherein the jumping point identifier identifies the fifth peer;transmitting a return message to the third peer, wherein the return message includes the path identifier and the jumping point identifier; andtransmitting the content to the requesting peer through a transfer path including at least the third peer, the fourth peer, and the fifth peer.
