Apparatus for Encrypted Communication on Network
First Claim
1. An adapter device connected to a network for encrypted communication, the apparatus comprising:
- a memory for storing connection policy information for a first communication device connected to the network and a second communication device connected to the adapter device;
a communication controller for judging a method of communication from the first communication device to the second communication device by using the connection policy information; and
an encrypted communication unit for discarding communication data received from the first communication device if the communication controller makes a judgment of encrypted communication and the communication data is not encrypted.

Abstract
An adapter device connected to a network for encrypted communication includes: a connection management unit for performing connection control for connection with a first communication device connected to a network via an access management server or a network outside the network; a storage unit for storing connection policy information for a first communication device and a second communication device directly connected to the adapter device; a communication control unit for judging a method of communication with the first communication device and the second communication device by using the connection policy information; and an encrypted communication unit for encrypting/decrypting communication data to/from the first communication device and the second communication device if the communication control unit makes a judgment of encrypted communication.
