Combining TCP and UDP for Secure Data Transfer


Objective of this paper is to enchance the security while tranfering data between two host through internet. It is very obvious that technology is evolving. As technology evolves the threat for user’s data also increases. Enhancement in data security has become a basic necessity. This paper also works towards enhancing the security of data through 6 layers. The data that have to be sent to the receiver will pass 6 layers of security on the sender’s side. The first layer comprises of any encryption algorithms. The second layer involves compression techniques. The third layer involves a new technique of key generation. In the fourth layer the data will be traversed in any one of the 9 existing patterns. Fifth layer is to append the data with another text, audio, video or image file. Final layer combines both the two basic networking protocols, Transmission Control Protocol and User Datagram Protocol. The byte array of this appended file will be sent through the User Datagram Protocol. The Generated key will be sent through the transmission Control Protocol. Transmitting data and the key in different protocols improves the security to a greater extent. The working of all these 6 layers will be discussed in this paper. Improvements will be made refer to increasing the performance and security without affecting the complexity level on client and server side. Region based segmentation can be used to hide the data in a particular part of the image. The implementation of these improvements is in process, to enhance the security of the data.
