Abstract
The utility model relates to a USB (universal serial bus) memory disc based on a mobile module, which includes a Flash encryption chip, a memorizer interface, a singlechip, a USB interface and the mobile module, wherein the Flash encryption chip is connected with the singlechip through the memorizer interface, the singlechip is connected with the USB interface through four edge connecting wires, and the mobile module is connected with the singlechip through an I/O (input/output) port; the USB memory equipment based on the mobile module has the following remote management functions: the use information management function for the USB memory equipment can realize acquisition of use time and use positions of the USB memory equipment; the remote verification function for the USB memory equipment can realize secondary verification on the USB memory equipment; and the remote destruction function for the USB memory equipment can realize remote destruction of data in the USB memory equipment.
Description
Technical field
The utility model belongs to information security practical technique field; The USB memory disc that relates to a kind of telemanagement problem of the USB of solution memory disc based on mobile module; Data message through encrypting module protection USB memory disc; Realize the remote management capability of USB memory disc through mobile module (gsm module or CDMA module), thereby guarantee the safety of information in the USB memory disc (individual USB flash disk).
Background technology
USB memory disc (also being individual USB flash disk or flash disk) product has developed so far since being born; Quite ripe; It has small and exquisite portable; Many advantages such as capacity is big make flash disk become modern society's one of mobile storage instrument the most easily, and most users are kept at personal information and important secret in the middle of the flash disk.But lose easily because the flash disk volume is little, the opening that simultaneously general flash disk uses makes flash disk become the media of revealing important secret and individual privacy the most easily, can not let the user arbitrarily use relievedly.
Along with enterprise secret is revealed, customer data is stolen and network on the taking place frequently of all kinds of cases such as " door incidents ", safety of data also has been pushed to the teeth of the storm thereupon, the consumer improves rapidly the protection consciousness of data message.Arise at the historic moment for adapting to the various encryption of this demand USB memory disc, these are encrypted the USB memory disc and have solved the encryption memory function of USB, but have no idea to solve the remote management capability of USB memory disc.How guarantee to be stored in the USB safety of data is badly in need of solving from data encryption and two aspects of telemanagement.
Summary of the invention
The purpose of the utility model is to solve to prevent the data disclosure risk that the USB flash disk accident is lost or the illegal possessor's visit of quilt brings and a kind of USB memory disc based on mobile module of realizing the USB memory disc is realized remote management capability through SMS is provided.
The purpose of the utility model is achieved in that and comprises Flash encryption chip 1, memory interface 2, safety chip 3, USB interface 4 and gsm module 5; It is characterized in that: wherein Flash chip 1 is connected with single-chip microcomputer 3 through memory interface 2; Mobile module 5 is connected with single-chip microcomputer 3 through the I/O port, and USB interface 4 is connected with single-chip microcomputer 3 through 4 edge joint lines.
The utility model principal feature is a remote management capability of having realized the USB memory device, and these management functions comprise the use information management of USB memory device, can realize service time, the use location of USB memory device are gathered; To the remote authentication function of USB memory device, can realize the re-authentication function of USB memory device; To the remote destroying function of USB memory device, can realize the remote destroying function of the data of USB memory device.The USB memory device in use; The USB memory device can send the positional information of random authentication number and USB device automatically and give the USB memory device owner; The USB device owner can be according to information; At any time destroy the memory block of USB memory device, perhaps carry out the USB memory device and use through the random number of sending.
Description of drawings
Fig. 1 is the USB memory disc structural map based on mobile module.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment 1: a kind of USB memory disc based on mobile module; Comprise Flash encryption chip 1, memory interface 2, safety chip 3, USB interface 4 and gsm module 5; It is characterized in that: wherein Flash chip 1 is connected with single-chip microcomputer 3 through memory interface 2; Mobile module 5 is connected with single-chip microcomputer 3 through the I/O port, and USB interface 4 is connected with single-chip microcomputer 3 through 4 edge joint lines.
Flash encryption chip 1 is used to realize the encryption memory function to user profile.The data of storage are that the form with ciphertext leaves among the Flash, and key produces at random, is placed on chip internal, even obtain the data among the Flash, does not have key, and what appeared is the mess code of failing to understand.
One-chip computer module 3 realizes that the data that write or read are carried out encryption and decryption to be handled;
One-chip computer module 3 sends to remote handset with the log-on message of USB and the random number that self produces through mobile module;
One-chip computer module 3 provides the authentification of user function, and authentication function was divided into for two steps: being the authentication function to original password on the one hand, is the checking to the verification code information of user's answer on the other hand.
One-chip computer module 3, through the effect of exchanges data between USB interface realization Flash chip and the external equipment, one-chip computer module is realized the authentication function to user identity simultaneously.
USB memory disc based on mobile module carries out telemanagement, and is specific as follows:
When step 1, said USB memory disc access terminal equipment, system can point out the user to input password, and the user imports and accomplishes and wait for;
Step 2 is verified the password of user input, if success then produce an identifying code at random and sends to the log-on message of identifying code and USB device on the user mobile phone with way of short messages, if mistake then point out the user to re-enter;
Step 3, the user checks the log-on message and the identifying code of USB device, confirms to use USB device, then imports correct pass code information; If the USB device accident is lost and the password that is stolen, in order to guarantee the safety of information in the USB device, the user can the message reply destroy command, and canned data in the Flash chip is destroyed, and prevents that the data in the USB memory disc from being stolen by other people;
Step 4, the verification code information that the user is replied compares, and correctly then normally starts the USB memory disc; Otherwise the prompting user re-enters; If what the user replied is destroy command, then need the short message prompt user whether really will the USB memory disc be destroyed, the user reply confirmation then system automatically USB device is destroyed, if the user replys mandatum cassatorium and then gets back to operation steps three.
In step 2, the thresholding that the user imports security pin sign indicating number number of times is set, if the number of times of authentication error surpasses said thresholding, then carry out fault processing.
In step 2, the log-on message of USB comprises the time of login, the IP address information of login.
In step 4, after the USB memory disc is destroyed, USB device can't use, and data are wherein also destroyed fully, can't recover.
Said identifying code is a random number.
