MODIFIED AES WITH RANDOM S BOX GENERATION TO OVERCOME THE SIDE CHANNEL ASSAULTS USING CLOUD

Abstract

Development of any communication system with secure and complex cryptographic algorithms highly depends on concepts of data security which is crucial in the current technological world. The security and complexity of the cryptography algorithms need to get increased by randomization of secret keys. To overcome the issues associated to data security and for improvising it during encryption and decryption process over the encrypting device, a novel Secure Side Channel Assault Prevention (SSCAP) approach has been projected which will eliminate outflow of side channel messages and also provides effective security over the encrypting device. An effective Enriched AES (E-AES) encryption algorithm is proposed to reduce the side channel attack; the modified algorithm in this research shows its improvement in the Generation of Random Multiple S - Box (GRM S-Box) which makes it hard to the attacks to break the text which is in encrypted form. Our novel SSCAP approach also improves the security over the original information; it widely minimizes the leakage of the side channel information. Attackers cannot easily get a clue about the proposed S-Box Generation technique. Our E-AES algorithm will be implemented in cloud environment thereby improving the cloud security. The proposed SSCAP approach is judged against the existing security based algorithms on the scale of encryption and decryption time, time taken for generating the key, and performance. The proposed work proves to outperform over all other methods used in the past.
