Cipher machine and cryptogrammic operation implementation method based on host machine

The invention relates to a cipher machine and a cryptogrammic operation implementation method based on a host machine. A plurality of virtual cipher machines are configured on the host machine connected with an entity cipher module, each virtual cipher machine comprises a virtual network card, a cipher service module and a virtual cipher module, wherein different IP addresses are configured on the virtual network card which is used for receiving a cryptogrammic operation request sent by an application system, and is further used for feeding back an operation result to the application system; the cipher service module is used for receiving the cryptogrammic operation request from the corresponding virtual network card and calling the corresponding virtual cipher module, and is further used for receiving the cryptogrammic operation result fed back by the corresponding virtual cipher module, and feeding back the cryptogrammic operation result to the corresponding virtual network card; and the virtual cipher modu
