A Novel Identity-Based Digital Signature SchemeCompliant with GOST 34.10-2018 and Its Applicationin Digital Government Systems

Abstract

GOST 34.10-2018 serves as the official standard for public key cryptography in the Russian Federation, constituting a vital pillar of the broader GOST regulatory framework. This standard specifies a digital signature algorithm characterized by high security and performance, predicated on Elliptic Curve Cryptography (ECC). Due to its robustness and alignment with national security requirements, it is officially mandated for use in governmental information systems, financial transactions, and diverse cryptographic applications. However, as digital ecosystems evolve toward complex architectures—such as digital transformation and Digital Government—the need for streamlined and efficient certificate management becomes increasingly paramount. This paper addresses that challenge by proposing a novel, secure, and efficient Identity-Based Signature (IBS) scheme based on the GOST 34.10-2018 standard. Unlike traditional Public Key Infrastructure (PKI), our identity-based approach allows a user’s public key to be derived from unique identifiers, significantly reducing the administrative burden of certificate revocation and storage. The security of the proposed scheme is rigorously evaluated within the Random Oracle Model (ROM), demonstrating existential unforgeability against sophisticated forgery attacks. Furthermore, we perform a comprehensive performance analysis, assessing the computational cost in comparison to existing publications and experimental efficacy. Results indicate that the signature process maintains high throughput and low latency. Consequently, the proposed scheme is both theoretically sound and highly viable for practical integration into modern digital infrastructures, ensuring alignment with established digital signature standards and operational efficiency.
