Algorithm for Text Data Encryption by Position Swapping based on LFSR Pseudorandom Key Generation

Abstract

Data security is one of the main issues as the technology is rising. Daily infinite amount of data is being transmitted over the internet, through mobile phones, laptops, and it is of more concern that, that data should be secured. Cryptography gives us number of ways by which the security can be enhanced. Number of encryption algorithms and protocols are there, by which the data can be made more and more secure. Cryptography is the science where security engineering meets mathematics. In this paper, a basic two level encryption algorithm has been proposed based on the position swapping of data values according the values of key and LFSR pseudorandom sequence generation for making the transmission of text data secure.
