Abstract: Nowadays, protecting sensitive factual information from hackers when it is transmitted over the broad network to communicate around the world is a huge task. To provide secure online transactions, communication, and business, researchers are insisted to develop novel security techniques. One of these approaches is on the basis of encrypting a plaintext will be in ciphertext by applying some mathematical models. This paper suggested a modified Blowfish algorithm with Fermat’s Little Theorem to provide an additional layer of security for sensitive information while sending over a non-secure channel. The performance analysis of Modified Blowfish Algorithm and Fermat’s Little Theorem (BFLT) encryption algorithm reveals consumption of memory, time consumption for encrypting and decrypting by comparing with the standard encryption algorithm. According to the analysis, this proposed encryption algorithm provides significantly upper level of performance and security and BFLT can be used for real-time implementations.
