    • A radio communication terminal and a radio communication system which can avoid an obstacle that is caused by a malicious wormhole while using a harmless wormhole. There are provided: a radio communication terminal in which a relay route about a certain node is stored as a backup route about the node and the backup route is changed and set as a relay route about the node in accordance with a detection of an obstacle caused by application data; and a radio communication system in which a sink node transmits a transfer destination change command in association with the change setting and a node which received the command sets a node of a transferring source of the command as a transfer destination node.

    • A communication device receives secure communication frames on which a security transform has been performed to permit authentication. The communication device maintains an authentication history and a local time varying parameter. In multi-hop communication, the communication device provisionally verifies the freshness of a received secure communication frame by verifying that identifying information extracted from the frame is not already present in the authentication history and that a received time varying parameter extracted from the frame is not older than the local time varying parameter by more than a certain margin. If these freshness tests both pass, the frame is authenticated. If authentication succeeds, the frame is transmitted on the next hop without performance of a new security transform.
    • 通信装置接收安全通信帧,在其上进行安全变换以允许认证。 通信设备维护认证历史和本地时变参数。 在多跳通信中,通信装置通过验证从帧中提取的识别信息不存在于认证历史中并且从帧提取的接收到的时变参数不是较老的,临时验证接收到的安全通信帧的新鲜度 比当地时变参数多一定余量。 如果这些新鲜度测试都通过,则该框架被认证。 如果认证成功,则在下一跳发送帧,而不执行新的安全转换。
