Patent number: 11563717Abstract: A generation method includes identifying, as paths that are abstraction candidates, dynamically generated paths among paths in a profile that is used to determine whether each request to a server is an attack, and counting numbers of path variations corresponding to the respective paths that are abstraction candidates, and abstracting paths contained in the profile when a number of variations counted at the counting satisfies a certain condition, by processing circuitry.Type: GrantFiled: April 15, 2019Date of Patent: January 24, 2023Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Kunio Miyamoto, Shingo Orihara, Yuta Iwaki, Yo Kanemoto, Yuichi Murata

Publication number: 20210209504Abstract: A learning device generates a character class sequence abstracting a predetermined structure of a character string included in requests to a server. Also, the learning device saves an appearance frequency of each combination of predetermined identification information and character class sequence, which are included in requests for learning among the requests, as the profile. Also, the learning device collates combinations of predetermined identification information and character class sequence, which are included in requests for analysis among the requests, with the profile to detect abnormalities. Also, the learning device selects at least part of the requests, which are for analysis. Also, the learning device updates the profile based on the selected requests.Type: ApplicationFiled: April 19, 2019Publication date: July 8, 2021Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Shingo ORIHARA, Yo KANEMOTO, Yuta IWAKI, Kunio MIYAMOTO, Yuichi MURATA

Publication number: 20210203677Abstract: A learning device generates a character class series abstracting a structure of a predetermined character string included in each of requests to the server which have been generated in a predetermined period. Also, for each of the combinations of the predetermined identification information and the character class series included in the requests, the learning device calculates a score for update which becomes higher as the number of times of appearance of the combination is increased and becomes higher as the appearance of the combination is continued. Based on the score for update, the learning device updates the profile of each combination for determining whether the request is an attack or not.Type: ApplicationFiled: April 16, 2019Publication date: July 1, 2021Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Yuta IWAKI, Shingo ORIHARA, Kunio MIYAMOTO, Yo KANEMOTO, Yuichi MURATA

Patent number: 10652211Abstract: When an attack is detected, a controller samples an attack-target addressed DNS reply, received by a border router, from each of the border routers. Then, the controller adds the transmission-source IP address of the sampled DNS reply to the black list of the border router. Furthermore, upon reception of any of a target-addressed DNS reply and a target-addressed UDP subsequent fragment from the IP address that is described in the black list, the controller gives a command to the border router to discard the packet. Furthermore, the controller specifies the setting, for each of the border routers, that DNS replies to a DNS request from the target are excluded from discarding.Type: GrantFiled: November 18, 2015Date of Patent: May 12, 2020Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Yuichi Sudo, Takahiro Hamada, Masami Ueno, Yuminobu Igarashi, Hideo Kitazume, Bo Hu, Yuichi Murata

Patent number: 6817321Abstract: A control to enable a further degree of enhancement in combustion efficiency in an automobile by effectively performing temperature control of cooling water in an automobile engine in accordance with various states of operation. Parameters from a variety of sensors that detect the state of an automobile engine are input into an engine control unit. Then, when the engine control unit determines from values of the accelerator opening and engine rotation speed, which serve as parameters indicating the operating state of the automobile, that the engine load is about to decrease, control is performed in the electronic control thermostat to maintain the cooling water temperature at a high temperature. Conversely, when it is determined that medium or high loads are due to increase, the control method is switched such that the electronic control thermostat is controlled by reading a target temperature corresponding to these parameter values from the engine control unit.Type: GrantFiled: May 27, 2003Date of Patent: November 16, 2004Assignee: Nippon Thermostat Co., Ltd.Inventors: Toshiharu Takei, Yuichi Murata

Patent number: 5307781Abstract: A cam shaft reduces noise produced by gears used to drive cams of a fuel injection pump. Conventionally, the gear noises are caused by negative torque of a cam shaft. A cam profile of each cam which lifts a plunger of the fuel injection pump is shaped like a fan. There are formed two cams in a single cam shaft. A lift increment segment of a first cam overlaps a lift decrement segment of a second cam to prevent a negative torque.Type: GrantFiled: April 24, 1992Date of Patent: May 3, 1994Assignee: Isuzu Motors LimitedInventors: Teruo Nakada, Yuichi Murata, Naoyuki Soma
