The objective of the work is to enhance the data security through the performance metrics of encryption and decryption using blowfish algorithm.A total of samples(N=10) are collected from a dataset.Blowfish is cryptography method that uses identical secret key for both the encryption and decryption of plain text comparing with innovative DES, which is also a symmetric key block symmetric-key block cipher following Feistel structure uses separate identical subkeys for both encryption and decryption.In this work performance metrics of encryption and decryption using blowfish has lower time complexity i.e (0.2ns-1.2ns) than DES.Time complexity(2ns-3ns) for DES is very high.Blowfish algorithm appears to have a slight increase in significant value of p = 0.012(p<0.05).The results prove that the blowfish has lower time complexity than DES.Blowfish takes less memory for encryption and decryption.
