State convergence in the initialisation of the Sfinks stream cipher

Alhamdan, A., Bartlett, H., Simpson, L., Dawson E. and Wong, K. K.

    Sfinks is a shift register based stream cipher designed for hardware implementation. The initialisation state update function is different from the state update function used for keystream generation. We demonstrate state convergence during the initialisation process, even though the individual components used in the initialisation are one-to-one. However, the combination of these components is not one-to-one.
