摘要： Provided are a method and apparatus for generating a pseudo-random number which is unpredictable and which has a small memory work area, and also a method and apparatus for encrypting data, for each predetermined amount, based on the generated pseudo-random number. A seed is divided into a predetermined number of blocks, new blocks are created by calculating an exclusive-OR of the blocks being different from each other, and the new blocks are merged to generate a new pseudo-random number. The data is encrypted for each determined amount based on the generated pseudo-random number. At this time, a pseudo-random number to be used for the succeeding encryption is generated by using as a seed a predetermined amount of random number of the pseudo-random number used for the preceding encryption of the predetermined amount of data.

摘要： A system and method of transmitting data across a first link aggregation formed by an intermediate switch and a downstream switch, the intermediate switch adopting a Media-Access Card (MAC)-address-based load sharing algorithm for distributing traffic among links to the downstream switch interfaced with a final destination device. The method comprises: receiving a packet having a MAC header and an IP header at an input port of an upstream switch for transmission from the upstream switch to the intermediate switch, the upstream switch and intermediate switch forming a second link aggregation; re-writing, at the upstream switch, the source MAC address of the received packet to a different source address; sending the packet through the second link aggregation to the intermediate switch, the intermediate switch implementing the load sharing algorithm for sending the packet to the downstream switch along a link through the first link aggregation to the destination device.

摘要： A sliding assist mechanism includes a case (1) attached to one of a main body (7) and a mobile body (A); a latch (4) movably disposed in the case and switched between a standby state in which the latch is locked in the case and a retracted state in which the locking is released; a biasing device (3) for biasing the latches in one direction; and an operation member (8) attached to the other of the main body (7) and the mobile body. When the latch (4) is switched.from the standby state to the retracted state, the sliding assist mechanism allows the mobile body to move from a first position to a second position on a main body side through the operation member (8) by biasing force accumulated in the biasing means (3). Essential parts of the mechanism include an engagement portion (42) at a normal time when the latches (4) engage the operation members (8) by interlocking the switching from the standby state to the retracted state, and an auxiliary engagement device (47) releasably engages the operation members (8) when the latch comes to the retracted state in a non-engaged state of the operation member relative to the engagement portion. A repairing structure can be further simplified by such sliding assist mechanism.
