Abstract: Nowadays security plays important role whenever there is communication between sender and receiver. To triumph over the issues of security intruders, various cryptographic algorithms are used. In this paper, authors have attempted to improve the security level of blowfish with proposed Inter bit exchange and merge (IBEM) pattern of data before applied which is fed into S-Boxes. Inter bit Exchange and Merge (IBEM) pattern of data allows the intruders cannot easily find key mechanism what the user actually send. The results of all the tests conducted which leads to a common conclusion that the security of the Inter bit Exchange and Merge process provides data in great secure manner when compared to original blowfish algorithm.
