A New Improved ZS Algorithm for a Synchronous Stream Cipher
H. Lee, Sang Jae Moon · Applied signal processing · 1999
When we apply a synchronous stream cipher to the T1 carrier system, long consecutive-zero sequences can occur in the received random ciphertext data. In this case, the sequences give difficulty in recovering the receiver clock and the zero suppression (ZS) algorithm with block detection has been proposed to prevent consecutivezero sequences of more than k = ($2). In this paper we propose a new improved ZS algorithm to apply stream cipher directly using a serial detection method, and analyse its properties.
