To achieve security in wireless sensor networks (WSN), communications between sensor nodes need to be encrypted and authenticated. Therefore, keys for encryption and authentication must be agreed among the communicating nodes. At the same time, small memory, weak processor and limited battery power of a sensor node are the major obstacles to implement the traditional security primitives. Owing to both the requirement and obstacles, this paper proposes an efficient key establishment protocol that establishes keys between $\tau$ number of its communicating nodes at a single instance, and therefore the proposed scheme reduces the execution cost.
