Abstract
An encryption apparatus enables encrypted communications using existing network equipment which does not have an encryption function, such as a server, a client, or a router. The encryption apparatus is connected to a section between a terminal and a network, data from the terminal is encrypted and sent to the network, data from the network is decrypted and sent to the terminal, and a connection control frame between the terminal and the network is not encrypted.
