— Security plays an important role in most of the applications where small change of data can lead to major problems. Hence there is a need for a stronger encryption which is very hard to break. In order to achieve better results and improve security, information has to pass through several levels of encryption. A multilevel encryption-decryption of original text into cipher data with each character encoded uniquely into its corresponding cipher and eliminating the possibility of any pattern(s) is proposed in this paper. It is graceful that elegantly and ingeniously simple and ciphers the data to two levels of encryption. The analysis shows that there is an improvement in the efficiency compared to conventional schemes.
