Study of the security of the generalized self-shrinking sequences
Dong Li · Journal of Xidian University · 2003
The security of generalized selfshrinking sequences are analyzed when a short sequence of keystream bits is lost. By using the initial reconstruction algorithm in the paper we have proved that for vk=ak+s, the security of generalized selfshrinking sequences is very weak when s is smaller than L, where L is the length of LFSR.
