Abstract
The present invention relates to a system for authentication management of a sensor node having a subscription processing function, and a method for operating the system. Upon receiving information about a sensor node allocated with an IP address, the system supports the access of only authorized user equipment to a corresponding sensor node, which blocking any direct access of unauthorized user equipment to the sensor node, thereby strengthening the security of the sensor node. According to the present invention, a relay server receives subscription information from user equipment. The relay server checks permission validity of corresponding user equipment. If the user equipment has a valid permission, the relay server transmits the subscription information to a sensor node, and transmits subscription acceptance information to the user equipment. Then the sensor node transmits the collected and stored information to the user equipment having a valid permission.
