[0004] In the existing internal network environment with strict security control, it can usually support ISO / IEC 7816 interface contact smart card, ISO / IEC 14443 interface inductive smart card and ISO / IEC 18092 interface near field communication smart card, but due to security In the specific setting, the use of external storage devices is strictly restricted, which directly leads to the inability of the storage interface smart password key to be used in these internal network environments
That is, in the prior art, the storage interface smart password key cannot be used in various network computing environments
This has greatly restricted the application range of storage interface smart password keys, and is extremely unfavorable to the promotion and popularization of storage interface smart password keys

The invention relates to a smart card adapter for a memory interface smart password key, which comprises a memory card slot, a switching chip and an external port. The switching chip comprises a memory interface protocol process unit, a protocol converting unit and a smart card protocol process unit which are sequentially connected. The memory interface protocol process unit is connected with the memory card slot, and the smart card protocol process unit is connected with an external smart card reader. The invention further relates to a method for achieving the application of the smart card by utilizing the smart card adapter. The protocol converting unit converts a smart card protocol message to a corresponding memory interface communication protocol message, transmits the communication protocol message to the memory interface smart password key, converts a operating result fed back by the smart password key to a corresponding smart card protocol message, and returns to the external smart card reader, so that the memory interface smart password key is switched to the smart card reader, and the application of the smart card is achieved. Therefore, the memory interface smart password key can be used in various calculating environments, and the application range is widened.
Description
technical field [0001] The present invention relates to the technical field of smart cards, in particular to the technical field of switching heterogeneous interface smart cipher devices into smart card interfaces, and specifically refers to a smart card adapter and control method applied to storage interface smart cipher keys Background technique [0002] At present, common smart password key products have a variety of interface forms, including contact smart card ISO / IEC 7816 interface, inductive smart card ISO / IEC 14443 interface, near field communication ISO / IEC 18092 interface, USB Key interface and SD card interface and many other forms. [0003] The current mainstream mobile platforms do not support external smart cards with the above-mentioned interfaces. In order to solve this problem, a storage interface intelligent password key has been developed in the prior art. That is, a smart security chip is added to the memory card widely used on mobile platforms to provi...
