Detailed Description
The embodiment of the invention provides a data storage card and a data storage method.
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a data storage card, including: the SIM card 101, the encryption module 102 and the storage module 103, wherein the encryption module 102 is respectively connected with the SIM card 101 and the storage module 103;
the SIM card 101 is connected to a terminal device through a first contact 104 disposed on the SIM card 101, and is configured to implement information transmission with a communication network;
the encryption module 102 is configured to obtain key information from the SIM card 101;
the storage module 103 is connected to the terminal device through a second contact point 105, and is configured to implement data transmission with the terminal device according to the key information.
The SIM card 101 in the data storage card may be used as a main card of a terminal device into which the data storage card is inserted or as a sub-card of the terminal device.
In one embodiment, the terminal device adopts a dual card slot design, where a first card slot is used for placing a SIM card as a main card, and a second card slot is used for placing the data storage card of the embodiment of the present application.
In the data storage card, the SIM card 101 adopts a design mode similar to that of the current conventional SIM card, and a first contact point 104 of the SIM card is arranged on the SIM card 101. And a second contact point 105 is also provided on the data storage card. After the data storage card is inserted into the terminal device, the SIM card 101 is connected to the terminal device through the first contact 104 to realize information transmission with the communication network, and at the same time, the storage module 103 is connected to the terminal device through the second contact 105 to realize data transmission between the storage module 103 and the terminal device.
After the data storage card is inserted into the terminal device, the encryption module 102 may obtain the key information through the SIM card 101 and store the key information. The key information is used for data encryption and data decryption in the data transmission process between the storage module 103 and the terminal device. If the encryption module 102 does not have the key information, the data transmission between the storage module 103 and the terminal device cannot be normally realized.
The data stored in the storage module 103 can be pictures, words or programs readable by the terminal device, but is essentially stored by the computer, that is, all data are represented by two numbers 0 and 1, and the two numbers 0 and 1 are records of positive and negative voltage fluctuations received on the second contact point 105, and when the data need to be read, that is, the operation is reversed, and 0 and 1 are identified by the positive and negative voltage fluctuations. The data encryption process belongs to hardware encryption, namely when data is written into the storage module 103 from the terminal equipment, the encryption chip randomly reverses 1 or more contact points 0 and 1 identification modes and records the data in the key information. At this time, the data stored in the storage module 103 is reversed due to the partial contact point identification mode, so that the entire file cannot be read correctly. Only by means of the corresponding key information is it known which contact points have their 0 and 1 identification reversed, so that a fast hardware level encryption is achieved, i.e. the data in the memory module 103 can only be correctly decrypted by means of the key information corresponding to the data.
For example, if data 00110011 in the mobile phone represents "good" characters, when the terminal device transmits the data to the storage module 103, a transmission point identification mode changes during encryption retransmission, the data that should be stored as 0 in the storage module 103 originally becomes stored as 1 and becomes 01110011, and the meaning of the whole data representation changes, thereby implementing encryption.
In one embodiment, since the data in the storage module 103 is sequentially written and read, if further encryption is required, even a regular mode change may be performed on the second contact point 105, such as a mode change every X numbers, to improve the security of encryption.
The key information may be stored on the terminal device or on the communication network.
In one embodiment, the encryption module 102 is configured to obtain the key information from the communication network through the SIM card 101.
Further, the SIM card is bound with the key information.
When the terminal device writes data into the storage module 103, the generated key information is bound with the SIM card and then stored in the communication network. Before reading the data in the storage module 103, the communication network needs to authenticate the SIM card 101, and after the authentication is passed, the key information is issued to the SIM card 101, and the SIM card 101 sends the key information to the encryption module 102 and stores the key information.
After the user loses the data storage card or the SIM card 101, the SIM card 101 and the key information bound to the SIM card 101 may be temporarily invalidated in a manner of directly reporting loss of the SIM card, so as to further ensure the security of the key information.
Further, the encryption module 102 adopts a power loss data mode.
When the data storage card is pulled out of the terminal device, or the terminal device is powered off, the encryption module 102 will remove the stored key information. And after the data storage card is inserted into the terminal equipment or the terminal equipment is started, acquiring the key information from the communication network again.
Further, the SIM card is further configured to instruct the terminal device to input a password before the encryption module obtains the key information.
After a data storage card is inserted into a terminal device or the terminal device is restarted, firstly, an input password is set and displayed on the terminal, and then, under the condition that the password input by a user is determined to be correct, key information is obtained from a communication network.
Thus, the data stored in the data storage card will have at least the following three layers of protection:
1. the data in the storage module is encrypted, and cannot be decrypted without the key information;
2. the key information is stored in the communication network and bound with the SIM card. After the SIM is lost, the safety of the key information can be ensured by making the SIM card invalid;
3. the user can acquire the key information by inputting the password in the terminal equipment, so that the safety of the key information is ensured.
In one embodiment, if the user needs to replace the terminal device, the data storage card may be inserted into the original terminal device, the original terminal device encrypts the data and stores the encrypted data in the storage module 103 of the data storage card, and the generated key information is bound with the SIM card 101 of the data storage card and stored in the communication network. And after the user inserts the data storage card into the new terminal equipment, the new terminal equipment prompts the user to input a password. After the input password is determined to be correct, the communication network authenticates the SIM card 101, and after the authentication is passed, the key information bound with the SIM card 101 is sent to the encryption module 102 of the data storage card for storage. After the data of the original terminal device stored in the storage module 103 is decrypted according to the key information, the data is read by the new terminal device, so that the data is quickly migrated.
According to the technical scheme provided by the embodiment of the invention, the embodiment of the invention comprises a user identification card, an encryption module and a storage module, wherein the encryption module is respectively connected with the user identification card and the storage module; the user identification card is connected with the terminal equipment through a first contact point arranged on the user identification card and is used for realizing information transmission with a communication network; the encryption module is used for acquiring key information from the user identification card; the storage module is connected with the terminal equipment through a set second contact point and is used for realizing data transmission with the terminal equipment according to the key information. By the embodiment of the invention, the safety of the data in the data storage card is improved, and the rapid migration of the data is realized.
Based on the above embodiment, further, the data storage card further includes a card slot, and the card slot is used for inserting the SIM card.
The data storage card can be set to be a card sleeve mode, and a user can insert an SIM card into the data storage card according to the requirement of the user, or a new card sleeve is replaced for the SIM card, so that the capacity of the storage module is increased.
