Outline
With the introduction of the action plan for the development of trusted data space, advancing the transaction and circulation of data elements has become a national strategy. As the core technology and fundamental support of network security, cryptographic technology possesses the characteristics of confidentiality, integrity, authenticity and non-repudiation, which strongly supports data security in trusted data space. Focusing on the scenario of data element circulation, this paper constructs a commercial cryptography security assurance system from three dimensions of technology empowerment, standard alignment and management synergy. By sorting out the security application requirements in the whole life cycle of data, this paper proposes a layered and decoupled cryptographic application framework, establishes a standard system covering general basic specifications to application evaluation, and builds a comprehensive management mechanism integrating institutional norms, supervision and evaluation, as well as policy coordination. Comparative analysis with traditional data security and cryptographic application systems shows that the proposed system has significant advantages in the integration depth of data business and cryptographic functions, full-link security protection, and the coordination of standards and management, which provides a theoretical reference and practical path for the secure and efficient circulation of data elements.
