Patent number: 8503677Abstract: 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.Type: GrantFiled: November 18, 2010Date of Patent: August 6, 2013Assignee: Oki Electric Industry Co., Ltd.Inventors: Taketsugu Yao, Kiyoshi Fukui, Jun Nakashima

Publication number: 20110078311Abstract: As a defense against cyber attacks, a network communication device permits other communication devices to associate and undergo entity authentication, registers the identifiers of devices that pass entity authentication in a memory, and communicates only with those devices. As a further defense, the network communication device may also impose association control by normally refusing to let other communication devices even associate. The network communication device monitors the communicability of devices with identifiers registered in the memory. If communication with a device becomes disabled, its identifier is removed from the memory and placed in a whitelist. Whitelisted devices may re-associate even while association control is in effect. A device that experiences outage may therefore re-associate autonomously, without requiring human intervention.Type: ApplicationFiled: July 2, 2010Publication date: March 31, 2011Applicant: OKI ELECTRIC INDUSTRY CO., LTD.Inventor: Jun Nakashima
