Quantum Cryptography (QC) uses a property of laws of quantum mechanics to generate a random key for secure communication. To use QC in Wireless Sensor Networks (WSN) are very challenging task. In order to make secure communications around WSN, communication between sensor nodes and base station to sensor node should be handled carefully. In this paper, the authors propose a 128 bit key management scheme using Three-Stage Quantum Cryptographic Protocol (TSQCP) for WSN. TSQCP is communicating based on symmetric polynomial approach. In the proposed method, each sensor has a secret key and a unique identity.
