Differential Fault Analysis on High Throughput AES

T. Soundarya

Abstract: Cryptography plays a key role in ensuring the privacy and integrity of data. Cryptanalysis is the study of how to crack encryption algorithms and their implementations. Differential cryptanalysis is a plain text attack which occurs in the cryptographic system. Testing can control and observe the internal states of the system. While testing in the cryptographic system, by observing the input and output bit changes, the third parties may shift out key. To reduce the observability and to increase the security, Robust secure scan design (RSS) is proposed. RSS design encrypts the content during scan chain operation. By adding pipelining process in the S Box and transforming the S Box transformation into combinational design, 50 % high throughput is achieved over the standard Encryption algorithm. By this method the security is much improved as it incorporates RSS design, which involves double encryption process
