Improved rapid AES for secure digital images

Rapid growth of technology make possible use of many types of data. Reduced costs of communication charges and many electronic gadgets is leading to increase in the number of users and hence generation of large volumes of data over public networks. Consequently security breaches and threat to information security is major issue of concern. Encryption methods play a key role in providing security. Advanced Encryption Technique is proven to be one of the best methods for text encryption. Image pixels being highly correlated, demand strong and variant encryption methods. In this paper a variant of AES algorithm is presented which ensures security and resistant to various Cryptanalysis.
