In this paper, the authors present a new combined cryptographic method called Modified UES Version-I. Researcher has already developed several symmetric key methods. It combines three different methods namely, generalized modified vernam cipher method, permutation method and columnar transposition method. Researcher recently developed few efficient combined encryption methods such as TTJSA, DJMNA where they have used generalized MSA method, NJJSAA method and DJSA methods. Each of the methods can be applied independently to encrypt any message. Researcher showed that TTJSA and DJMNA are most suitable methods to encrypt password or any small message.
