Abstract(in English)	Privacy information, in many cases, is included in the information flowing through sensor networks. Therefore, effective data encryption is needed to ensure security, and an efficient key management scheme is required. At SCIS2010, Ooami presented an efficient key management scheme for sensor networks. However, in his method, a larger number of participating nodes required a larger number of keys, and the method to prevent key analysis was to renew the element key. On the other hand, some authors have presented a hierarchical key management scheme that is based on sharing of node IDs. In this study, we investigate a large-scale network-based simulation that is conducted using these two methods and compare their performance.
