Circular No. 50/2025/TT-BKHCN stipulates that QCVN 137:2025/BKHCN is the mandatory regulation for public digital signature certification services starting from July 1, 2026.

QCVN 137:2025/BKHCN establishes a legal framework for the comprehensive standardization of public digital signature certification services. This regulation sets strict security requirements, ranging from cryptographic algorithms, data formats, and digital signature certificates to specialized key storage devices such as HSMs or smart cards. The core of the document is to build a set of operational criteria and control mechanisms for three simultaneous methods of public Digital Signature Authentication: hardware-based signing, remote signing, and mobile signing. Synchronizing these standards not only ensures information security but also serves as the foundation for transparently managing conformity assessment processes and the compliance responsibilities of organizations.

However, this regulation is only mandatory for the public service sector and foreign electronic signature certification service providers seeking recognition in Vietnam, and does not apply to digital signature certification services exclusively serving public duties.

In conclusion, Circular No. 50/2025/TT-BKHCN and the accompanying QCVN 137:2025/BKHCN serve as the technical backbone for reliable Digital Signature Authentication in Vietnam’s evolving digital landscape. By standardizing the requirements for infrastructure, from HSM security to remote signing models, this regulation ensures that Digital Signature Authentication provides the highest level of legal certainty and data integrity. In 2026, every public provider of Digital Signature Authentication must strictly adhere to these benchmarks to maintain their license and support the national digital transformation.

Ultimately, the rigorous implementation of Digital Signature Authentication under QCVN 137:2025/BKHCN mitigates risks in high-stakes sectors like banking and e-government. As mobile and remote signing becomes the norm, the unified framework for Digital Signature Authentication fosters cross-border trust and seamless electronic transactions. For businesses, prioritizing certified Digital Signature Authentication is not just a regulatory obligation but a critical strategy for securing customer trust. Staying compliant with the latest Ministry of Science and Technology (MOST) mandates on Digital Signature Authentication is essential for any entity operating within the Vietnamese digital economy.
