The method for authenticating a sensor node by a first sink node in a sensor network includes receiving an authentication request using an authentication ticket from the sensor node, identifying a second sink node which has issued the authentication ticket, decoding the authentication ticket using a group key, which is previously stored in correspondence to the second sink node to confirm the validity of the authentication ticket, when the second sink node is included in a neighboring node list, normally processing authentication for the sensor node, generating an authentication ticket using a group key of the first sink node, and transmitting the generated authentication ticket to the sensor node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for authenticating a sensor node in a sensor network","description":"A method and apparatus for authenticating a sensor node in a sensor network.
