Several schemes to establish secret key between sensor nodes in wireless sensor network for secure communication has been proposed. But due to lack of priori deployment knowledge and limited resources of sensor nodes and security threats, it is always challenging to propose a better scheme apart from existing. In this paper, the author have suggested a novel idea for secure communication in wireless sensor network (WSN) using BCH code. Here communication key and connectivity key are used separately for more secure communication. He have created connectivity key using BCH code. In this scheme a new approach has been proposed to establish a secure communication between sensor nodes with desired scalability and resiliency.
