A kind of cloud computing data encryption device of the present utility model, system configuration is simple and reliable, and cost is lower, has good autgmentability.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is system construction drawing of the present utility model.
Fig. 2 is workflow diagram of the present utility model.
Embodiment
Implementation procedure of the present utility model is introduced in detail below in conjunction with accompanying drawing.
Fig. 1 is the system construction drawing of a kind of cloud computing data encryption device of the present utility model.A kind of cloud computing data encryption device comprises FPGA master control borad, USB interface, memory cell and touch screen unit, described FPGA master control borad and USB interface, memory cell and touch screen unit are equipped with transmission line, described USB interface realizes the exchanges data of FPGA master control borad and cloud computing tenant terminal, described cell stores cryptographic algorithm data, its output is connected to FPGA master control borad, described touch screen unit receives the input instruction of user, and shows cryptographic algorithm and arrange relevant information.The control chip of FPGA master control borad adopts EP1C20F324C8N, and USB interface control chip adopts CY7C68013A, and the storage chip of memory cell adopts ST24W16.
Fig. 2 is workflow diagram of the present utility model, and workflow is as follows:
1) after device starts, first by the current operable encryption algorithm type of touch-screen display of touch screen unit;
2) user is by the encryption algorithm type of touch-screen choice for use;
3) encryption algorithm type that user selects by FPGA master control borad is sent to cloud computing tenant terminal by USB interface;
4) encryption algorithm type that user selects by cloud computing tenant terminal is sent to cloud computing server by system for cloud computing and audits, if examination & verification is passed through, then License Info is sent to FPGA master control borad by USB interface, and then shows on the touchscreen, inform user; If examination & verification is not passed through, then the information that will disapprove is sent to FPGA master control borad by USB interface, and then shows on the touchscreen, informs user, proceeds step 2);
5) data of cloud computing tenant terminal needs encryption are received by USB interface;
6) cryptographic algorithm selected is used to be encrypted data;
7) by USB interface, the complete data of encryption are sent to cloud computing tenant terminal;
8) what judge whether to receive that user inputted by touch-screen resets cryptographic algorithm instruction, resets cryptographic algorithm instruction, then forward step 2 to if received), otherwise forward step 5) to.
