Multiple Dimensional Fault Tolerant Schemes for Crypto Stream Ciphers

To enhance the security and reliability of the widely-used stream ciphers, a 2-D and a 3-D mesh-knight Algorithm Based Fault Tolerant (ABFT) schemes for stream ciphers are developed which can be universally applied to RC4 and other stream ciphers. Based on the ready-made arithmetic unit in stream ciphers, the proposed 2-D ABFT scheme is able to detect and correct any simple error, and the 3-D mesh-knight ABFT scheme is capable of detecting and correcting up to three errors in an n2-data matrix with liner computation and bandwidth overhead. The proposed schemes provide one-to-one mapping between data index and check sum group so that error can be located and recovered by easier logic and simple operations.
