Abstract: In the era of a global village, a huge amount of people are connected to the web through their PC, mobile and any type of communication tool for communication purposes, hence we require a safe approach that provides security and protection from unauthorized clients and misuses of data and information. Cryptography is a widespread technique to guarantee security for the internet-based communication framework. Many cipher technique have developed but the rail Fence is the simplest and amusing cryptographic algorithm until now. In this technique, the plain text is organized as crosswise and read it from top to the bottom row produces the cipher text. An inadequate quantity of keys is its weakness. This paper redesigned the current rail fence by applying the three basic phases: substitution phase once and transposition phases uses twice. The proposed technique ensures that the resultant cipher text is a fusion of various symbols precise by a chart. The proposed algorithm eliminates the limitation of the existing algorithm and significantly improves the performance by transforming the plain text unrecognizable and unpredictable.
