Background
Generally, in the initial implementation stage of each smart card project, a small number of test cards need to be manufactured to cooperate with clients to debug the server and perform online test on the cards. The current practice is to complete card making in a development office or production shop before the card is taken to the customer site or mailed to the customer by technical support personnel. The debugging period of some complex items is very long, and the customer does not require technical support personnel of the card to participate in the debugging in the whole process, but only needs to give the card to the customer, and the customer carries out the debugging and feeds back the problem. In the debugging process, if the chip operating system COS (chip operation system) needs to be modified, another batch of cards are manufactured and delivered to a client. Obviously, the process of making and handing cards for multiple times can prolong the debugging period.
In addition, the remote desktop technology is also a scheme which can complete remote operation at present. Because the remote desktop technology manages the entire computer operation right of the client at the control end, there are limitations such as security of the client computer, requirements for internet bandwidth, and the like. This solution is therefore rarely adopted by customers.
In the existing scheme, each modification of the card COS causes the interruption of the debugging and testing process for 1 to 3 days. The technical unfamiliarity of the customer with the card COS modification and update results in the inability to directly submit this work to the customer.
Therefore, a solution for remotely modifying the card COS is urgently needed, and in the solution, only the client needs to cooperate to establish remote connection, the operation authority of the whole computer of the client is not needed to be controlled by the control terminal, and all other technical details of the operation process should be transparent to the client.
