    Abstract : Software Defined Networking (SDN) is a technology which provides a network architecture with three distinct layers that is, the application layer which is made up of SDN applications, the control layer which is made up of the controller and the data plane layer which is made up of switches. However, the exits different types of SDN architectures some of which are interconnected with the physical network. READ MORE

  3. 3. PHYSICAL LAYER SECURITY USING PSEUDO-RANDOM SEQUENCE KEY GENERATION

    University essay from

    Author : Srihari Arolla; Naga Venkata Sai Teja Gurrala; [2018]
    Keywords : Physical Layer Security; Bit Error Rate; Key Error Rate; Pseudo Random Generator; Secret Key.;

    Abstract : Nowadays, network security plays a major role in the field of wireless communications. Wired networks propagate electrical signals or pulses through cables. Whereas wireless signals propagate through the air. If wireless networks are left open and exposed to the outside world, there are high chances of being misused by others. READ MORE
