Annotation: The paper proposes a digital signature scheme that expands the functionality of the GOST 34.10-2018 and allows delegating signing capability to a trusted person (proxy signer). A classification of proxy signatures has been developed; the selected delegation scheme was modified to prevent misuse by a proxy signer. The correctness of the scheme was shown, the analysis of compliance with security requirements was carried out. The results of software implementation testing are presented.
Keywords: digital signature, proxy signature, GOST 34.102018, elliptic curves.
