Abstract

In present days, Internet has become mainstream of the network technology for low cost communications architecture, also it brought great convenience for the organizations and businesses to support growth of their business. Since Internet is highly available in almost all the regions, it is oftenrequired by the businesses for their local presence. Thus, a secure channel within this communication network is required for the security of the confidential data traversing in the public network. Due to rapid growth of the digital devices and their access to the Internet caused security threats to user data. Advance measures and high technical skills adapted by the attackers, security and privacy threats has become more and more sophisticated day by day, which increases the demand foran updated and highly secure medium to secure entities and their valuable information into the Internet. There are many solutions present in the market today to choose from, out of which Virtual Private Network (VPN) is highly preferred to create a secure medium within the public Internet. It provide convenience of public network and security of private network by forming a tunnel between sender and receiver. VPN also encrypt upper level protocol information contained in its header. This paper discusses about the traditional security measures of VPN and a whole new approach for VPN security by using multi-phase encryption technique [1]. Since most user does not care about the complex underlying technologies, rather they are only concerned about the security of their data traversing in the public network. Thus, the proposed solution will only applicable for the security of user's data carried by the VPN Header. Additionally, the proposed solution will increases the complexity ofencryptionalgorithm used by VPN techniquewhich will enhances the security commitment of the user's privacy in the public communication network.
