Abstract

In this paper, the author proposes a new combined symmetric key cryptographic method, which is based on the following steps: 1) In first step, the position number of each byte in the string (stream) of message (plain text file) is added to the ASCII value of each byte; 2) In second step, Single Bit Manipulation technique is applied to each byte; 3) In third step, Advanced Bit Randomization technique is applied to blocks of data after converting each byte to its equivalent binary format; 4) In fourth and final step, Bit Reversal technique is applied to form the encrypted message (output file). The second and third steps are totally random in nature and are depended on the password (symmetric key), which is provided for encryption method. It is evident from the steps above that the method used here is an amalgamation of both byte and bit manipulation cipher techniques. This method has been tested for many plain text files and other type of file formats, and the results were very satisfactory. There was no pattern found in the output file and spectral analysis of the frequency of characters also proves this.
