An Encryption Algorithm for Enhanced Image Security

Abstract

Image security finds its applications in many areas such as bio-metric, digital signatures, watermarking, confidentiality of medical and data in transit. It has become necessary to secure the images in order to protect the confidential data. Cryptography is one of the methodologies through which image data can be secured for storing or transmission purposes by encrypting the same and decrypt it when needed. The main challenge in image encryption is generating cipher which takes less computational without compromising the security. In this paper, we present a symmetric encryption algorithm which outperforms the existing algorithms such as AES, DES, Blowfish and etc which require more computational time on bulk amounts of data.
