Wireless sensor networks are an emerging technology for low-cost, unattended monitoring of a wide range of environments. In WSNs sensor nodes are densely deployed either inside the phenomenon or very close to it. In this paper security is implemented in WSNs protocol LEACH-C. In WSNs though, energy efficiency is an important performance metric, directly influencing the network lifetime. The other important factor for WSNs is security, as sensor nodes communicate sensitive data, so it is necessary to ensure that any intruder or other neighboring network could not get confidential information intercepting the transmissions.
