Abstract :
In this paper the method to counter differential fault analysis attack on LFSR-based stream ciphers have been proposed. The realization of the proposed method in the stream ciphers, based on reconfigurable LFSR are much more efficient than traditional hardware-oriented redundant technique. For real world application fault detection circuit has been developed. The overheads for the proposed DFA countermeasure method realization have been analyzed.
