Abstract: We consider frequencies and cross-correlation coefficients for sequences generated by the stream encryption algorithm GEA-1. Results are obtained by means of well-known estimates for exponential sums from linear recurrent sequences.

Key words: linear recurrent sequences, filter generators, additive character sums, cross-correlation function.
