Method and apparatus of ensuring security of communication in home network
First Claim
11. An apparatus enabling secure communication between a control apparatus and a controlled apparatus in a home network, the apparatus comprising:
- a register channel establishing unit establishing a registration Secure Authenticated Channel (SAC) with the controlled apparatus through a TLS-PSK protocol using a Product Identification Number (PIN) that is an identifier given to the controlled apparatus at time of manufacture; and
a register performing unit generating a private key, sharing the private key with the controlled apparatus via the registration SAC to registering the control apparatus in the controlled apparatus.

Abstract
Provided are a method and apparatus to ensuring communication security between a control apparatus and a controlled apparatus in a home network. The control apparatus in the home network establishes a registration Secure Authenticated Channel (SAC) with the controlled apparatus by using a Transport Layer Security Pre-Shared Key ciphersuites (TLS-PSK) protocol implemented by using a Product Identification Number (PIN) of the controlled apparatus input from a user, shares a private key with the controlled apparatus via the registration SAC, and uses services of the controlled apparatus via a service SAC established by using the TLS-PSK protocol implemented by using the shared private key to easily implement a framework ensuring communication security in the home network.
