Information accessing method for computer network e.g. Internet, modeling finite state machine using state transition matrix and generating analysis module for each application protocol using interpreter to filter transmitted data

摘要

A finite state machine is defined for each application protocol (8) and machines are modelled using a state transition matrix. An analysis module (14) is generated for each protocol by an interpreter to filter transmitted data. The module has information processing units for verifying conformity of data transmitted with respect to the protocols and restraining possibilities offered by the protocol, respectively. An Independent claim is also included for an access device for providing secure logical access to information.
