There is a need of using secure key media in order to store key information. Apart from the tasks of direct key media using by the user, there is a necessity to use the key media for server tasks. However, the possibility of direct use of a secure key storage medium in servers is not always possible. E.g., when using NCIs on virtual servers in public cloud infrastructures.
Therefore, there is a nesesary of transfer requests from a remote virtual server to a workstation where a secure key storage connected medium is  directly controlled by a responsible person. 
Operation of the Module and the Library predicts  connection of the Library to the Module with the locally protected carrier of the key information by a network on the TCP/IP protocol.
