Abstract
A communication method for a data sharing system which is constituted by a plurality of communication nodes, and through which data transmitted from a transmission source node are propagated by having the respective communication nodes repeatedly transmit the data, includes: a transmission step in which a first communication node transmits a transmission stop message including a hash value of data in relation to which repeated transmission is to be stopped; a reception step in which a second communication node receives the transmission stop message; and a stopping step in which the second communication node stops transmission of data having an identical hash value to the hash value included in the transmission stop message. The hash value is preferably encrypted using a public key cryptosystem. A transmission source node of the transmission stop message may be a transmission source node or a destination node of the data to be stopped, or another node.
