Image Encryption Using AES with Modified Transformation

Harleen Kaur ^[8] | Reena Mehla ^[2]

Abstract: With the increased growth of internet, extensive exchange of data over the network has been made. Safe storage of digital images and secure transmission over the network is always been required, so as to protect the confidential data from unauthorized access. High transmission rate of the images using limited bandwidth, makes the standard algorithms unsuitable for encryption. The work proposed in this paper is focussed on a new algorithm, which requires less encryption time, less computational power requirement and maintain a sufficient level of security. This paper proposes a modified version of AES. Various modifications have been made in the transformation steps of AES. Experimental results for encryption time using proposed AES have been shown and compared with original AES.
