In this paper we have some modification in Caesar Cipher Technique. We have proposed a method to enhancing the Caesar cipher for more efficient and secure. We use Relative Frequency of Letters in Alphabets. We arrange the sequence of letter according to the frequency in increasing ordered. And then we have made use of a Modified Caesar cipher technique with double Columnar Transposition Technique
