Network security has been an area of concern and with more and more devices getting connected to the internet, security is an indispensable functionality. Statistics show that, networks are attacked every day and we need to keep protecting the data and network from different types of attacks. In our work we have considered security issues specifically for voice communication over a mobile device. The security features implemented in the proposed work differ from existing systems. Existing systems rely on the service provider for confidentiality and authentication. In our work security measures are implemented at the device. Thus this system can provide better security when the security measures provided by the service provider are compromised. Additionally the work can also be used to provide confidently in Bluetooth networks.
