PACKET ROUTING DEVICE AND PACKET ROUTING METHOD

摘要

The present invention provides a packet routing device capable of converting packet data complying with one of a plurality of secure protocols received via an external network into the one complying with a secure protocol used for a home network at home. A packet routing device (101) includes a first network I/F unit (201), a decryption unit (202), a protocol conversion unit (203), an encryption unit (204), a second network I/F unit (205) and a memorizing unit (801). The first network I/F unit (201) receives the packet data complying with one of the secure protocols used for the external network. Then, the protocol conversion unit (203) converts the received packet data into the one complying with a secure protocol used for the home network, with reference to a table (802) memorized by the memorizing unit (801).
