Abstract

There are provided a method for setting a sensor node and setting security in a sensor network, and a sensor network system including the same. A setting apparatus scans a near field communication apparatus included in the sensor node to obtain information on the sensor node. The information on the sensor node is transmitted to a gateway, and the gateway connects the sensor node to the sensor network using the received information on the sensor node.

Claims

1. A method for setting a sensor node in a sensor network, comprising:

scanning, by a setting apparatus, the sensor node to obtain information on the sensor node;

selecting a gateway that is to be connected with the sensor node;

transmitting the information on the sensor node to the selected gateway; and

requesting, by the selected gateway, the sensor node to make a connection.

2. The method of claim 1, wherein

the sensor node includes a near field communication apparatus, and

the obtaining of the information on the sensor node includes scanning, by the setting apparatus, the near field communication apparatus to obtain the information on the sensor node.

3. The method of claim 1, wherein

the information on the sensor node includes an ID of the sensor node.

4. The method of claim 1, wherein

the selecting of the gateway includes:

obtaining a position of the sensor node; and

selecting the gateway that is to be connected with the sensor node using the obtained position.

5. The method of claim 4, further comprising

transmitting, by the setting apparatus, a setup request message to a managing server,

wherein the transmitting of the information on the sensor node includes transmitting, by the managing server, a bind request message to the selected gateway, and

the setup request message and the bind request message include the information on the sensor node.

6. The method of claim 1, wherein

the selecting of the gateway includes

scanning, by the setting apparatus, the gateway to select the gateway.

7. The method of claim 6, wherein

the transmitting of the information on the sensor node includes transmitting, by the setting apparatus, a bind request message to the selected gateway, and

the bind request message includes the information on the sensor node.

8. The method of claim 5, wherein

the setup request message further includes information on the setting apparatus,

the method further comprising:

transmitting, by the managing server, an authentication code to the setting apparatus using the information on the setting apparatus; and

transmitting, by the setting apparatus, an acknowledge message including the authentication code to the managing server.

9. The method of claim 7, further comprising

transmitting, by the managing server, a passcode to the setting apparatus and the selected gateway,

wherein the bind request message further includes the passcode.

10. The method of claim 1, wherein

the requesting of the sensor node to make the connection includes:

transmitting, by the selected gateway, an invite request message to the sensor node;

transmitting, by the sensor node, a challenge message including a first random value to the selected gateway;

converting, by the selected gateway, the first random value and a secret key into a first hash value using a hash function;

transmitting, by the selected gateway, the first hash value to the setting apparatus; and

requesting, by the setting apparatus, the selected gateway to make a connection.

11. The method of claim 10, wherein

the invite request message includes a second random value, and

the requesting of the sensor node to make the connection further includes:

converting, by the sensor node, the second random value and the secret key into a second hash value using the hash function; and

transmitting, by the sensor node, the second hash value to the selected gateway.

transmitting, by the selected gateway, an invite request message to the sensor node;

transmitting, by the setting apparatus, a challenge message including a random value and a connect message for a connection request to the selected gateway;

converting, by the selected gateway, the random value and a secret key into a hash value using a hash function; and

transmitting, by the selected gateway, the hash value and admittance of the connection to the setting apparatus.

13. The method of claim 1, wherein

the requesting of the sensor node to make the connection includes:

transmitting, by the gateway, a connect message to the sensor node;

transmitting, by the sensor node, a challenge message including a random value to the selected gateway;
