Abstract

In the present work, it is shown that the binary sequences obtained from a cryptographic generator, the so-called generalized self-shrinking generator, are just particular solutions of a type of linear difference equations. Cryptographic parameters e.g. period, linear complexity or balancedness of the previous sequences can be analyzed in terms of linear equation solutions. In brief, computing the solutions of linear difference equations is an easy method of generating new sequences with guaranteed cryptographic parameters.
