摘要： The apparatus 10 is set on the line between the first and second computers 1,2 which respectively communicates by a protocol, such as TCP, having a flow control. The delay between the first computer 1 and a position, at which the apparatus 10 is set, is less than the delay between the position and the second computer 2. The apparatus 10 sends and receives a packet to/from the computers 1,2. The apparatus 10 transfers to the second computer 2, a data packet sent from the first computer 1 and being larger than a maximum data amount notified by the second computer 2. The apparatus 10 transfers, to the first computer 1, a data packet sent from the second computer 2, but does not transfer, to the first computer 1, an ACK packet sent from the second computer 2. The apparatus 10 generates, instead of the second computer 2, an ACK packet for a data packet sent from the first computer 1 and then sends the ACK packet to the first computer 1. Therefore, in a case that a large delay section having exists in the line between the computers 1 and 2, it is possible to perform a high speed communication on one way by only setting one apparatus 10.

摘要： A method, an apparatus and a program for detecting spoofed Internet Protocol (IP) traffic directed to a network having a plurality of autonomous systems (AS) is provided. The method comprises receiving an incoming packet through an AS, the incoming packet containing a source IP address and a destination IP address, acquiring a corresponding source and destination IP address prefixes, converting the corresponding source and destination IP address prefixes into a source AS number and a destination AS number, determining if the incoming packet arrived from an unexpected source based upon the corresponding destination IP address prefix and the converted source and destination AS number using an unexpected pair tuple table generated from network routing information and generating an alert indicating that the incoming packet is not allowed to enter the network.

摘要： A method and apparatus for detecting spoofed IP network traffic is presented. A mapping table is created to indicate correlations between IP address prefixes and AS numbers, based on routing information collected from a plurality of data sources. At each interface of a target network, IP address prefixes from a training traffic flow are acquired and further converted into AS numbers based on the mapping table. An EAS (Expected Autonomous System) table is populated by the AS numbers collected for each interface. The EAS table is used to determine if an operation traffic flow is allowed to enter the network.

摘要： To reliably prevent the occurrence of a pull out phenomenon in a magnetic driving pump of a vehicle internal combustion engine where permanent magnets, magnetized to have alternate N poles and S poles around an axis of a drive shaft and a driven shaft, are respectively fixed to the drive shaft and the driven shaft. The drive shaft is interlocked with a crankshaft and the driven shaft is coaxially mounted with the drive shaft. Furthermore, the permanent magnets are magnetized to have alternate N poles and S poles 90 degrees or 180 degrees in phase in a peripheral direction.

摘要： The present invention provides systems and methods of cross-domain access control in which a client node (250) sends a request (250) for a resource to a resource server (260). In response, a local proxy server (270) automatically obtains a ticket having a revocation status (275) and forwards the ticket (275) to an authorization server (280) that communicates with the resource server (260) regarding access.

摘要： A communication system and a security assurance device are proposed, which are capable of assuring that a target party for communication is implementing security countermeasures. A server 3 transmits information 104 necessary for AC issuance to a security assurance authority 2. The security assurance authority 2 verifies the security of the server 3 during communication based upon this information necessary for AC issuance 104. And, when the security of the server 3 during communication is confirmed, the security assurance authority 2 issues an AC 105 which proves the security of the server 3 during communication, and transmits it to the server 3. Upon receipt of this AC 105, the server 3 transmits the AC 105 to a client 4, according to a connection request from the client 4. And, upon receipt of this AC 105, the client 4 verifies the security during communication of the server 3, based upon the AC 105.

摘要： A water pump attachment structure of a water-cooled internal combustion engine is provided to facilitate the maintenance of a valve train. A water pump attachment structure of a water-cooled internal combustion engine includes a semicircular cut-away surface of a water pump holder opposed to a semicircular surface of a cylinder head to form a water pump support circular hole. Screw members are passed through respective screw through-holes of the cylinder head and threadedly engaged with internal thread holes of the water pump holder. Thus, the water pump holder is fastened to the cylinder head. A water pump is fitted into and secured to the water pump support circular hole. A cylinder head cover is attached to the cylinder head by allowing their mating surfaces to conform with each other with the water pump holder liquid-tightly sandwiched therebetween.
