Summary:Internet a network of interconnected systems which is used to transmit different kinds of sensitive data is made secure by encrypting this data during transmission and protecting it against any kind of violation. This paper presents a symmetric data encryption algorithm developed in Python to encrypt images, making the transmission secure. The major computations performed in the algorithm are Mix Columns, Key dependent ex-or operation with upper and lower triangular sections of the matrix, Shift Rows, and Customized Sub Bytes transformation which provides diffusion and confusion. Results of various analysis performed on the algorithm prove its authenticity, confidentiality, and integrity.
