NETWORK - FILE SYSTEM BRIDGE

摘要

A network-file system bridge enables a network-non-compatible or a network- compatible device (1) to exchange data with a network (4). The network-file system bridge is realized via an embedded system comprising a data transfer layer (51) for connecting to a device (1), a data control layer (52) for controlling data, a data layer (53) for establishing a file system and a network layer (54) for connecting to a network (4). The network (4) is mapped to a common file system. Therefore a device (1) which is able to read data from and write data to a data bus (3) is able to exchange data with the network (4). The bus (3) can be realized as USB, i.e. the device (1) must be able to read data from or write data to an USB memory stick (2). A network-non- compatible or a network-compatible device (1) which exchanges data with a network (4) via the embedded system do not have to be part of that network (4) or support a network protocol. Because of the isolation of the network layer (54), the data layer (53), the data control layer (52) and the transfer layer (51) in the embedded system the data can be checked before it is transferred to a target device (1). Therefore in this pre-execution trusted computing technology the checking of the data is always possible before the processing of the data begins.
