ABSTRACT
Wireless Sensor Networks (WSNs) are critical component in many applications that used for data collection. Since sensors have limited resource, Wireless Sensor Networks are more vulnerable to attacks than other wireless networks. It is necessary to design a powerful key management scheme for WSNs and take in consideration the limited characteristics of sensors. To achieve security of communicated data in the network and to extend the WSNs lifetime; this paper proposes a new scheme called Symmetric Key Management Scheme (SKMS). SKMS used Symmetric Key Cryptography that depends only on a Hash function and XOR operation for securing homogeneous and heterogeneous hierarchical WSNs. Symmetric Key Cryptography is less computation than Asymmetric Key Cryptography. Simulation results show that the proposed scheme provides security, save the energy of sensors with low computation overhead.
