.... the smallest FCSR which generates the sequence if the 2 adic span is small (we call this the register sybthesis problem for FCSRs) This algorithm, which we call the 2 Adic Rational Approximation or RA algorithm, is based 6 on de Weger s lattice theoretic approach to p adic continued fractions [51]. The 2 adic span is a major new measure of cryptanalytic security. All future stream ciphers must pass this test. The taps q 1 ; q 2 ; q r on the cells of an FCSR correspond to the connection integer q = q r 2 r q r 1 2 r 1 q 1 2 1 and the sequence a 0 ; a 1 ; ....
