Over the internet and other network applications, the need for security is increasing each day due to its wide usage. There are a number of algorithms that have been developed for the secure transmission of data. This paper presents a novel approach for the generation of key using the Advanced Encryption Standard (AES) algorithm along with the Flower Pollination Algorithm (FPA). This combination is termed as Modified AES (MAES). Initially, a plain text of 128 bits is the input to this algorithm. This text is converted into a cipher text. The key generation is important for the generation of the S-Box (substitution box). The key generation in the proposed work is done using the Flower Pollination Algorithm. This step is done to generate the keys in such a way that the complexities of the S-Box enhances. This improves the security of the proposed approach for data transmission in a network. Then encryption is done. This is followed by decryption. Finally, the 128-bit plain text is retrieved at the receiver’s side. The MAES algorithm was compared with other traditional cryptographic algorithms. The proposed MAES algorithm yielded outstanding results.
