摘要： A tracker node verifies content possession by a peer node in a peer-to-peer content distribution system. Upon receiving an announcement that a peer node claims to possess a content item, the tracker node in one embodiment obtains the content item, selects a random portion of the content item; formulates a challenge based on the random portion of the content item and determines an expected challenge response. The challenge may comprise, for example, a request for a hash of the random portion (or alternatively, a hash of the random portion and a random seed value). The tracker node issues the challenge to the announcing node and verifies the announcing node's possession of the content item if the challenge response from the announcing node matches the expected challenge response.
