The Sansec Cloud Key Management System refers to the Key Management Interconnection Protocol (KMIP) and other relevant standards to enable communication between any encryption system and any key management system. Through KMIP's interoperability, users only need to deploy a key management system to manage all cryptographic systems in the enterprise. It supports the management of various cryptographic objects including symmetric keys, asymmetric keys, digital certificates, and authentication tokens, etc., simplifies the key management model, and provides implementation of a consistent key management strategy based on the user, so that encryption is easier to configure and manage, reduces the maintenance cost of the key management system, and meets the key management requirements of users for multiple applications and multiple services.
