Embodiment
Data card method of operation and data card that the embodiment of the invention provides strengthen the data card security of storage data, and are user-friendly to, and are illustrated below in conjunction with specific embodiment.
Fig. 1 is the schematic flow sheet of the embodiment of the invention one data card method of operation, and this method specifically comprises:
S101, reception operational order and authentication information;
S102, verify described authentication information,, then the data of data card storage are carried out described operational order if checking is passed through.
Wherein, aforesaid operations instruction and authentication information can receive by USB Driver interface, and authentication information can be the password of user's setting, and the data of storing in the data card can be the note that receives, the file of storing in the last network process etc.
The embodiment of the invention strengthens the data card security of storage data by increase proof procedure before the data of data card storage are operated.
Fig. 2 is the schematic flow sheet of the embodiment of the invention two data card methods of operation, herein be operating as read operation, the concrete steps of this method embodiment are as follows:
S201, data card receive reading command and authentication information;
Wherein, the specific implementation process can for: data card receives the reading command of computer by the USB Driver interface that is connected with computer, receive the authentication information of user's input on this computer by the interface, then this authentication information is sent to data card by USB Driver interface.Authentication information can be the password of user's setting, or universal password.This universal password is and IMEI that the recognition feature of unique cards such as ESN or MEID can obtain this universal password by specific algorithm, and can be by this algorithms of formulation such as equipment suppliers equally.。
S202, data card verify whether this authentication information is correct, if correct, execution in step S203 then, otherwise get back to step S201, and can point out checking not pass through.
S203, judge whether data to be read are enciphered data, if, execution in step S204 then, otherwise direct execution in step S205.
S204, data card are decrypted according to default decipherment algorithm data to be read, then execution in step S205.
For further strengthening fail safe, data card can be encrypted the storage data, especially can be to being kept at the file encryption in the external connection of storage card, adoptable cryptographic algorithm has numerous embodiments, for example symmetric encipherment algorithm, the encryption factor of this moment can be International Mobile Station Equipment Identity IMEI, Equipment Serial Number ESN, Mobile Equipment Identifier MEID, setting password or its combination etc. of data card, and then Ci Shi the encryption factor and data card realized binding.Encrypt the factor and can also take SIM, UIM, some features of smart cards such as USIM perhaps allow these smart cards assist authentications, and then Ci Shi the encryption factor has realized the binding with smart card.Before the reading encrypted data, adopt corresponding decipherment algorithm that data to be read are decrypted.
Concrete, encryption can increase respective code in the read-write driver, finished storing the encryption and decryption of data by driver module.
S205, data card read the data of storage, and the data that read are sent to computer.
Concrete, data card sends the data that read by the USB Driver interface that links to each other with this computer.
Be appreciated that handling process and embodiment two were similar when the instruction that receives when data card was delete instruction, only need that the operation among the step S205 is replaced with deletion and just can realize.
The method of present embodiment has realized the data of data card storage are read preceding checking, and can encrypt the storage data, thereby has strengthened the data card security of storage data.If adopt the scheme of universal password, even password is lost by domestic consumer, can guarantee that also user's data can be read by validated user forever, convenient for users.
Fig. 3 is the schematic flow sheet of the embodiment of the invention three data card methods of operation, and the heresy that is operating as is herein gone into operation, and the concrete steps of this method embodiment are as follows:
S301, data card receive and write instruction and authentication information;
Wherein, the specific implementation process can for: data card receives the instruction that writes of computer by the USB Driver interface that is connected with computer, receive the authentication information of user's input on this computer by the interface, then this authentication information is sent to data card by USB Driver interface.Authentication information can be the password of user's setting, or universal password.This universal password is and IMEI that the recognition feature of unique cards such as ESN or MEID can obtain this universal password by specific algorithm, and can be by this algorithms of formulation such as equipment suppliers equally.
S302, data card verify whether this authentication information is correct, if correct, execution in step S303 then, otherwise get back to step S301, and can point out checking not pass through.
S303, receive data to be written, and judge whether need be to data encryption to be written, if desired, execution in step S304 then, otherwise, execution in step S305.
S304, data card to data to be written according to the preset encryption algorithm computing after, execution in step S305 then.
For further strengthening fail safe, data card can be encrypted the data of storage, especially can be to being kept at the file encryption in the external connection of storage card, adoptable cryptographic algorithm has numerous embodiments, for example symmetric encipherment algorithm, the encryption factor of this moment can be International Mobile Station Equipment Identity IMEI, Equipment Serial Number ESN, Mobile Equipment Identifier MEID, setting password or its combination etc. of data card, and then Ci Shi the encryption factor and data card realized binding.Encrypt the factor and can also take SIM, UIM, some features of smart cards such as USIM perhaps allow these smart cards assist authentications, and then Ci Shi the encryption factor has realized the binding with smart card.
Concrete, encryption can increase respective code in the read-write driver, finished storing the encryption and decryption of data by driver module.
S305, data card are stored described data to be written.
The method of present embodiment has realized the data of data card storage are write preceding checking, and can encrypt the storage data, especially to being kept at the data in the external connection of storage card, solved under encrypted state and can only read the problem that can not write, thereby strengthened the data card security of storage data.If adopt the scheme of universal password, even password is lost by domestic consumer, can guarantee that also user's data can be read by validated user forever, convenient for users.
