摘要： On ad hoc networks in which connection relationships among communication terminals constantly change, the processing load increases when authentication is performed each time a connection relationship changes. According to this invention, when communication terminals possess the same common key, mutual authentication is conducted with that common key, and when communication terminals do not possess the same common key, mutual authentication is conducted with a public key. Communication terminals that conducted mutual authentication exchange and retain a common key that they selected and common keys received from other communication terminals. When neither communication terminal possesses a common key at authentication, one terminal creates a common key and distributes it to the other terminal, and when one terminal has a common key it creates that common key and distributes it to the other terminal. Further, a common key possessed by a communication terminal corresponding to a relay node is broadcast periodically.

摘要： A system for storing data including first and second storage systems, each having a disk controller and plural disks under control of the disk controller. The first disk controller receives plural first I/O requests each including a different first disk ID from the other first I/O requests, and determines if the first disk ID indicates one of the second disks. If the first disk ID indicates one of the second disks, the first disk controller obtains an address of the second disk controller and a second disk ID of the second disks, and sends a second I/O request to the second disk controller based on the obtained address and disk ID. Plural second I/O requests, whose target second disk is different from each other based on the different first disk ID, are sent from the first storage system to the second storage system.
