Research Experience Details:

• Cryptography provides security for the information which is very much required in the fast evolution of digital data exchange. There has been a tremendous enhancement in the field of cryptography, which tries to manipulate the plaintext so that it becomes unreadable, less prone to hacker and crackers, and again obtain the plaintext back by manipulating this unreadable text in some way. The main emphasis of the research work was to enhance the security of AES and other well-known block ciphers such as Blowfish and CAST algorithms.
• AES algorithm was made stronger by making the S-Box key dependent without changing the basic operations of
• The performance of Blowfish and CAST128 was improved by modifying its
• A new algorithm Blow-CAST-Fish is introduced by combining Blowfish and
• All the above algorithms were tested for security through Encryption quality, Key sensitivity, Histogram and Correlation coefficient analysis using digital
• Effect of removal of Shiftrows stage and Mixcolumns stage was

Now, the emphasis is on design and analysis of key scheduling algorithm and low area FPGA implementation.
