Wireless sensor networks are distributed wireless multi-hop networks of tiny low-cost and low-performance devices called nodes or motes. They are used to monitor some physical phenomenon, such as humidity, temperature, pressure, movement, light and so on, and to communicate measured data. They are often deployed in previously unknown and physically unsecured environments. The requirements on processing speed, memory, communication, lifetime of a node and security differ for each application and thus leave different amount of resources to provide security with. However, most cryptographic solutions, both symmetric and asymmetric, are based on some secret keys. Consequently, these keys are established and managed by a key management scheme (KMS). Based on the application, specific restrictions and relaxations are made on KMS. In this paper, study of a specific type of KMS has been done.
