摘要：
An apparatus for authentication of fragments using hash trees may include a processor. The processor may be configured to provide one or more data fragments and a hash tree representing the one or more fragments, send at least one first fragment accompanied by any nodes of the hash tree necessary to authenticate the one or more first sent fragments, and send one or more subsequent fragments accompanied by only some, but not all, of the nodes of the hash tree necessary to authenticate the one or more subsequent fragments with the other nodes that are not sent but are necessary for authentication having been previously sent in conjunction with a prior fragment.
