Nowadays, the technology of the wireless communication is replaced by the wires. WSN (Wireless Security Networks) is also a part of the wireless communication technology as it provides us the internet with high speed. As the other technology of the wireless communication technology are not secured or safe. Various issues related to security are reported in WSN (Wireless Security Networks). In this, authentication models and authorization network resources are used to save or protect it from the unauthorized use. The encrypted mechanisms or the authentication both are proposed for WSN ( Wireless Security Networks) security but still the WSN networks were not secured fully or these are also under the attacks like Passive attack, Active attack, Insider attack, close in attack, distributed attack. In this, we proposed a security scheme for the increase in its capability and the functions of the existing models. Also, in this, we will use scythe tool for the verification of our proposed security scheme.
