Internet of things (IoT) is the extension of the Internet to connect just about everything on this earth. Security of multimedia data is an imperative issue because of fast evolution of digital data exchanges over unsecured network. Multimedia data security is achieved by methods of cryptography, which deals with encryption of data. Most of the application uses Advanced Encryption Standard (AES) and modify it, to reduce the calculation of algorithm and for improving the encryption performance. In modified AES algorithm used 1-Dimensionla S-box instead of 2-Dimensional S-box. Theoretical analysis and experimental results prove that this technique provides high speed as well as low latency on data encryption and decryption. Modified-AES algorithm is a fast lightweight encryption algorithm for security of multimedia data. Achieved efficiency of proposed MAES is around 23.7% while previously it is 18.35%. The total latency of previous work is 29.983milli sec while this work achieved 38.161ns.
