METHOD FOR ENSURING COMMUNICATION SECURITY IN HOME NETWORK AND APPARATUS FOR SAME

摘要

Since a home network is dynamically set up independently of an infrastructure by a central administration, there exists a need for implementing a key distribution scheme without assumption for a trusted third party. In a home network, a controller creates a registration SAC (Secure Authenticated Channel) through a controlled device and a TLS-PSK protocol by using a PIN of the controlled device input from a user, shares a secret key through said channel, and uses services of the controlled device through a service SAC created through a TLS-PSK protocol by using the shared secret key.
