The present invention provides a technique for efficiently generating and validating external file handles at a storage operating system of a filer. According to one aspect of the technique, the storage operating system associates a unique internal file handle with each file or directory stored in the filer. This unique internal file handle is used to generate a corresponding external file handle. Unlike previous approaches, the internal file handle' representations do not change depending on the location of their corresponding files or directories, e.g., on-disk or in-core, within the filer, thereby simplifying file management within the filer. According to another aspect of the inventive technique, the filer executes a file-handle validation procedure to determine whether an external file handle received with a file access request has become invalid (or “stale”) as a result of an NVRAM failure in the filer. The file-handle validation procedure enables the filer to efficiently determine the validity of the external file handle without having to perform conventional time-consuming and processing-intensive operations. Advantageously, the inventive technique is preferably only applied to generation and validation of external file handles configured in accordance with a stateless file-system protocol, such as the NFS protocol. In this way, there is no overhead added to the filer's storage operating system for generating and validating external file handles configured in accordance with stateful file-system protocols.

A WEP key is generated from predetermined binary data and stored in an access point. The binary data is converted into an SSID using a predetermined conversion algorithm. The access point transmits the SSID in a beacon. A mobile game apparatus receives the SSID and recovers the binary data from the SSID using the predetermined conversion algorithm. Using the same algorithm as used for generating the WEP key, a WEP key is generated from the recovered binary data. Encrypted communication is performed between the access point and the mobile game apparatus using the WEP key.

In a data transmit / receive method for plurality of devices connected by a 1394 bus, a receiving device obtains a device-specific number of a transmitting device when starting to receive data. When a bus reset occurs, the receiving device again obtains the device-specific number from the transmitting device, and checks whether the device-specific numbers before and after the bus reset match. If the device-specific numbers differ, the receiving device obtains the device-specific number from all devices connected to the bus. If a device with the same device-specific numbers as prior to the bus reset is present among the obtained device-specific numbers, the channel number of the bus used for the transmitting of data is determined, and the receiving device starts receiving with that channel number. Then device authentication with the transmitting device is carried out, and key information for solving the encryption is obtained.
