Ensuring the security of data while being transmitted or stored is a very important issue for companies and end users. Cryptography is used to transfer the data in a form that is not understood by anyone apart from the intended recipients. The advanced standard encryption algorithm (AES) is one of the most secure encryption algorithms. However, due to the speed issue and computational complexity, it is not suitable for real time applications. In this paper, a modified scheme is developed for the encryption/decryption by modifying the MixColumns stage in the AES algorithm in order to increase the speed of the encryption/ decryption while maintaining the complexity level of the design to keep the security level equivalent to AES. The results show that the proposed modification increases the speed of the encryption/decryption in real time applications up to 150% in the encryption process and up to 500% in the decryption process.
