Technical scheme: disclosed one of the present utility model can protect data USB interface memory access, including USB storage sets
Standby, described USB storage device includes: kept secure district and common storage area.By setting in described USB storage in the utility model
Kept secure district and two regions of common storage area are set in Bei, data can be stored separately, by different storage modes,
Can will be able to disclosed data put in common storage area, the data of need for confidentiality be put in Bo Ami memory block, only can
Enough complete encryption certification can access data.The utility model arranges common storage in described digital independent equipment
District, facilitates daily use, when accessing common file, has the described digital independent equipment of common storage area as often
USB movable storage device use, i.e. insert i.e. deposit, easy to use.
USB interface access arrangement described in the utility model includes: have the digital independent equipment of encryption authentication function；Institute
State digital independent device suite in described USB storage device, then access host；Described USB storage device includes: main encryption is recognized
Card verification unit；Described digital independent equipment includes from encryption authentication check unit；Described main encryption authentication check unit to from
Encryption authentication check unit is authenticated verification, and authentication check is by the reading authority in open kept secure district；Authentication check is not
Pass through, kept secure district denied access.By adding the digital independent equipment with encryption authentication function in the utility model
Realize the encryption to data, be mechanically encrypted, encrypt more reliable.
The invention also discloses a kind of method of work that can protect data USB interface memory access, described can protect number
Being connected with the main frame being provided with USB host interface according to USB interface memory access, USB interface access arrangement is read out by main frame；
Described data USB interface memory access can be protected to include: to include USB storage device and digital independent equipment；Described USB
Storage device includes: kept secure district, common storage area and main encryption authentication check unit；Described digital independent equipment include from
Encryption authentication check unit；
The described method of work that can protect data USB interface memory access specifically comprises the following steps that
(A) described USB storage device is connected on main frame by described digital independent equipment
(B) main frame is attached detection to USB interface access arrangement；Determine after connecting, put in described USB storage device
The use authority of common storage area；
(C) main encryption authentication check unit in described USB storage device attempt to described digital independent equipment from adding
Close authentication check unit is encrypted authentication check；
If verification is passed through, the kept secure district in described USB storage device is open uses authority, and kept secure district can make
With；
If on described digital independent equipment from encryption authentication check unit can't pass verification, in described USB storage device
The use authority in kept secure district do not open, kept secure district can not use；The public affairs in described USB storage device can only be used
Coexist storage area；
(D) if described USB storage device is directly connected to main frame, encryption authentication check cannot be passed through, and can only use institute
State the common storage area in USB storage device.
Method described in the utility model cleverly by digital independent equipment is arranged from encryption authentication check unit with
Main encryption authentication check unit in USB storage device is mutually authenticated, and improves the safety of data by way of hardware
Property, also improve the convenience of use simultaneously.
Beneficial effect
Compared with prior art, the utility model has the advantage that
Described in the utility model can protect data USB interface memory access by between USB storage device and main frame add
Digital independent equipment, is obtained the use authority in kept secure district, improves data by way of hardware by authentication check
The reliability of secrecy so that the data in kept secure district can use under secure conditions, and simultaneously described USB storage sets
Standby USB storage device and the main frame of being directly connected to again, the convenient data using common storage area.
