Fault detection and correction scheme using RC4 stream cipher
S. Kiruba, A. Alfred Kirubaraj · 2016
Cryptography is a method of sending the data to the receiver in a secured manner. This method is used for transferring secured data in various fields like medical, research, hospitals, industrial sites, military applications etc. A Cryptographic attack exists, when the security of cryptosystem gets collapsed. In order to protect the cryptosystem from attack, an attack tolerant method is required. In this paper we have proposed a method to have attack tolerant algorithm by error detection and correction method. The attack tolerant method uses modified RC4 Stream Cipher. The modified RC4 Stream Cipher generates secret keys for encryption with the plain text to form Cipher text. Also, we use modified Matrix code algorithm for error correction in the secret keys generated by the modified RC4 Stream Cipher algorithm. The modified Matrix code algorithm can correct multiple errors in the secret keys generated. Thus the designed attack tolerant algorithm provides robustness to the corruption of secret data in communication standard and protocols.
