The algorithm for computing the function of chameleon-hash in the group of points on the elliptic curve with a view to its deployment into the national standard of digital signature DSTU 4145-2002 is proposed. The choice of chameleon-hash function to a point on the elliptic curve, which is necessary for the chameleon-signature based on the standard DSTU 4145-2002 is substantiated.
