In the company’s internal infrastructure, keys and certificates are widely distributed among various actors. These are not only machines (e.g. PCs), but also human participants accessing the infrastructure. Fast and easy integration of storage devices, network devices, personal devices with embedded memory (e.g. computers, cell phones, databases, etc.) is, therefore, an important task. Through the use of KMIP (Key Management Interoperability Protocol), the interconnection of different systems for cryptographic key operations is standardized by OASIS (Organization for the Advancement of Structured Information Standards). There are many well-known companies that have already integrated the KMIP protocol.
