Generalized self-shrinking sequences, simply named the GSS sequences, are novel periodic sequences that have many advantages in cryptography. In this paper, we give several results about GSS sequence's application to cryptography. First, we give a simple method for selecting those GSS sequences whose least periods reach the maximum. Second, we give a method for describing and computing the auto-correlation coefficients of GSS sequences. Finally, we point out that some GSS sequences, when used as stream ciphers, have a security weakness.
