METHOD FOR COMMUNICATING SECURELY END-TO-END OF WIRE COMMUNICATION NETWORKS AND WIRELESS COMMUNICATION NETWORKS BY USING SWITCHING FUNCTION OF COMMUNICATION PROTOCOL STACK, TERMINAL DEVICES AND RECORDING MEDIUM

摘要

A method and a terminal for providing end-to-end security communication for a wire communication network and a wireless communication network using a communication protocol stack switching function and a recording medium for the same are provided to transmit and receive data safely and reliably by providing a security communication function corresponding to an end-to-end encryption scheme through a logical switching control layer which logically executes switching for an upper protocol layer and at least two lower protocol layers on the protocol stacks corresponding to wire/wireless communication functions. A terminal(100) having one or more wire/wireless communication functions comprises a switching part(170) and an encryption processing part(160). The switching part(170) executes logical switching for an upper protocol layer, a lower protocol layer corresponding to at least one wire communication protocol, and a lower protocol layer corresponding to at least one wireless communication protocol on the protocol stacks corresponding to the wire/wireless communication functions of the terminal(100). The encryption processing part(160) encodes the data to be transmitted through a presently connected communication network among one or more wire/wireless communication networks. If a communication packet containing the encoded data reaches a logical switching control layer, the switching part(160) switches and provides the communication packet to a lower protocol layer corresponding to the presently connected communication network.
