Wireless Sensor Network (WSN) has many application such as environment sensing, building safety monitoring, earthquake prediction etc. Security is critical issue in sensor networks. A fundamental security service is to establish pair-wise key shared between two sensor nodes, which is basis of other security such as encryption and authentication. The prime problem in key management is to establish secure keys between the sensor nodes. To avoid this pair-wise key establishment is used. This scheme consists of two key pools. One key pool is hashed value of keys in another key pool.
