Home network service system and method using a security terminal based on the security technology according to the present invention is a privacy security technology that can prevent external intrusion, secure information transmission and privacy by highlighting authentication / integrity / confidentiality and Apply wired and wireless network security technology.

First, privacy security technology is for personal information protection by setting personal policy or request protection policy and dealing with location disclosure, time, date and accuracy based on profile. It also includes a request-based (Location Disclosure Always On / Off, Conditional Disclosure) and optional (Allow on-Demand Request) and mutual authentication systems to protect the user's location information by ensuring that no one can obtain location information without prior permission. Authentication and encryption system.

Next, wired and wireless network security technology has a 'digital signature' that guarantees the integrity of the signed message and the 'signature' which can be denied by the signer and the third party can verify the signed user. There is 'user authentication' to verify the ability or qualification of the subject to access the information of the system and to prevent the illegal use of the system or the improper transmission of the information.

Accordingly, the home network service system and method using a security terminal based on the security technology of the present invention block access to the system from the outside and control access to the system so that only a user with an authorized use right can access the system. We apply the object authentication protocol which is an object authentication security algorithm for. In addition, the present invention applies a digital signature algorithm (DSA) which is an electronic signature algorithm to prevent data contamination and to protect data from external attack.

Here, the object authentication protocol refers to a protocol capable of identifying who is communicating with. A typical example is user authentication based on ID-password. ISO / IEC 9798 is an international standard. The object authentication protocol can be divided into one-way authentication and two-way authentication, and the present invention can be applied to both of them. Considering the environment in which a user connects to the server, one-way authentication means that the server authenticates the user, and two-way authentication means that the server authenticates the user and that the server that the user is trying to connect to is correct.

The voice information is transmitted to the mobile terminal 100 possessed by the user through FM communication.

Here, a synchronization process for FM communication between the wall pad 210 and the mobile terminal 100 is required before transmitting voice information. In addition, the wall pad 210 and the mobile terminal 100 authenticate each other's accessibility using an object authentication protocol before communication for information transmission between them. That is, the wall pad 210 authenticates the mobile terminal 100 connected through the security algorithm using the object authentication protocol, and the mobile terminal 100 also uses a security algorithm using the object authentication protocol to authenticate the wall pad 210. Can be used.

The mobile terminal 100 receiving the voice information about the call received from the wall pad 210 to the cellular phone 220 outputs the voice information through the audio output unit 430, and the user uses the cellular phone 220.
