Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
The data encryption mode includes symmetric encryption, asymmetric encryption, encryption by a hash algorithm and the like, and the encryption by the hash algorithm is explained in the application.
The present application provides a product authentication method, and referring to fig. 1, fig. 1 is a schematic flowchart of a first embodiment of the product authentication method of the present application.
While embodiments of the product authentication method are provided in the present application, it should be noted that although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown or described herein. The product authentication method is applied to the wearable device main body, and for convenience of description, the description of the product authentication method by the execution main body is omitted below. The product authentication method comprises the following steps:
and S10, detecting the access of the watchband, and sending root key configuration data to the watchband.
For example, whether the watchband is accessed is periodically monitored, and after the watchband is inserted into the wearable device body, connectors on the watchband are respectively communicated with a General-purpose input/output (GPIO) interface and a Ground (GND) interface on an MCU (micro controller Unit) in the wearable device body, so that an IC (Integrated Circuit) on the watchband is communicated with the MCU, and at this time, the watchband access is detected. Specifically, when the watch band access is periodically monitored, the MCU pulls down the level of the GPIO interface and maintains the first preset time, if the watch band access exists, the IC in the watch band responds to the behavior of the MCU, namely, the level of the GPIO interface is also pulled down and maintains the second preset time, and when the MCU detects that the level of the GPIO interface is pulled down and is not actively pulled down, the watch band access is determined; if the watchband is not connected, the MCU does not detect that the level of the GPIO interface is pulled down beyond the time when the MCU actively pulls down the level of the GPIO interface. The first preset time and the second preset time may be set as needed, and this embodiment is not limited in particular. Monitoring for the presence of watchband access may also be accomplished by sensing circuitry, such as a hall sensor, near field communication module, and the like.
Illustratively, the connectors include pogo-pin connectors, dome connectors, wire connectors, and the like.
Illustratively, the IC has the following advantages: no extra power supply is needed, the design is simple, the encryption algorithm is difficult to break, the price is low, the cost performance is high, and the like. Therefore, the product upgrading can be completed on the basis of ensuring that the price is not greatly improved and the original design is changed.
Illustratively, the root key configuration data is data related to the root key, and specifically, the graph key is obtained after the root key configuration data and the root key are subjected to hash operation.
It should be noted that, the wearable device main body does not store the root key, but only stores the root key configuration data and the graph key, and during storage, the root key configuration data is stored in correspondence with the graph key, where the root key configuration data may be composed of random numbers. The root key is stored in the wristband, and, in order to improve the security of the root key, the memory in the wristband is set so as not to be read and written when the root key is stored in the wristband, that is, so as to be called only when the IC in the wristband needs to be used, and not to be read by the wearable device body in a communicative manner.
It should be noted that, although the hash operation is substantially irreversible, that is, the root key configuration data cannot be substantially deduced from the graph key in a backward direction, the root key configuration data and the graph key are not one set, but multiple sets, in order to make the data in the device more secure.
Note that, the conventional watchband has no IC for automatically identifying whether or not the watchband is inserted, and even if a part of the watchband has a function for automatically identifying whether or not the watchband is inserted, the function is realized by providing only a hall sensor, a resistor, or the like in the watchband. This makes the product identification differentiation of the conventional watchband low, and the IC in this embodiment can make the watchband store more configuration information, thereby improving the product identification differentiation.
Illustratively, after monitoring that the watchband is accessed, if data transmission fails when transmitting the root key configuration data to the watchband, the watchband can be determined to exit the access, at this time, the watchband is returned to the step of monitoring whether the watchband is accessed again, the root key configuration data is continuously transmitted to the watchband after monitoring that the watchband is accessed again, and the next step is started after the data is successfully transmitted.
And step S20, receiving first authentication data sent by a watchband, wherein the first authentication data is obtained by calculating the watchband based on the root key configuration data.
Illustratively, the first authentication data is obtained by performing hash operation on the root key configuration data and the root key, and performing hash operation on the hash operation result and the second graph key again. It will be appreciated that the process of the hash operation is performed by the IC in the watchband.
And step S30, second authentication data is obtained, and if the first authentication data is the same as the second authentication data, the watchband is determined to pass the anti-counterfeiting authentication.
If the first authentication data is the same as the second authentication data, the root key used for calculating the first authentication data and the second authentication data is the same root key, and at the moment, the watchband can be determined to pass the anti-counterfeiting authentication; if the first authentication data is different from the second authentication data, the root key used for calculating the first authentication data is different from the root key used for calculating the second authentication data, and the watchband can be determined not to pass the anti-counterfeiting authentication.
Exemplarily, if the watchband passes the anti-counterfeiting authentication, the next process is started; and if the watchband does not pass the anti-counterfeiting authentication, returning to the step of monitoring whether the watchband is accessed.
Illustratively, the obtaining the second authentication data includes:
step a, acquiring a first graph key and generating random data; wherein the first graph key corresponds to the root key configuration data.
Illustratively, the first graph key is obtained by performing a hash operation on the root key configuration data and the root key.
And b, carrying out hash operation on the first graph key and the random data to obtain second authentication data.
For example, since the second authentication data is calculated from random data, even if data leakage occurs during data transmission, the first graph key cannot be cracked reversely, so that the data security of the first graph key is further improved on the basis that the data security is improved by hash operation.
Illustratively, the determining that the watchband passes the anti-counterfeiting authentication comprises:
and c, reading the configuration information in the watchband.
Illustratively, the configuration information is used for configuring the working mode of the wearable device main body.
And d, switching the working mode to the working mode corresponding to the configuration information so that the wearable device main body works in the switched working mode.
Illustratively, the operation mode includes a sport mode, a joint mode, and the like. After the working modes are switched, the wearable device main body makes corresponding response so that the wearable device main body can adapt to the user requirements in the corresponding working modes. When the working mode is the movement mode, correspondingly, the watchband is the movement watchband, and after the configuration information is read, the movement mode is automatically entered from the current mode (generally, the standby mode), for example, the switching theme is the movement theme; when the working mode is the joint name mode, correspondingly, the watchband is the joint name watchband, and after the configuration information is read, the current mode automatically enters the joint name mode, for example, the theme is switched to be the joint name theme.
The automatic switching of the working modes is carried out according to the configuration information, the switching of the working modes manually carried out by a user is avoided, and the convenience of using the wearable equipment by the user is improved.
Compared with the prior art that the intelligent wearable product and the watchband do not have an anti-counterfeiting function, and the equipment data safety of the intelligent wearable product is low, the product authentication method is applied to a wearable equipment main body, and comprises the following steps: detecting the access of a watchband, and sending root key configuration data to the watchband; receiving first authentication data sent by a watchband, wherein the first authentication data is obtained by the watchband through calculation based on the root key configuration data; and acquiring second authentication data, and if the first authentication data is the same as the second authentication data, determining that the watchband passes anti-counterfeiting authentication. This application has realized after the watchband inserts wearing equipment main part, send root key configuration data to the watchband, can understand, this root key configuration data is relevant with the authentication, later receive the watchband and send carry out the first authentication data that obtains of calculating based on root key configuration data, and when first authentication data is the same with second authentication data, confirm the watchband and pass through anti-fake authentication, this application carries out data coprocessing together through watchband and wearing equipment main part promptly, thereby realize the anti-fake authentication to the watchband, make intelligent dress type product and watchband possess anti-fake function, and then improve the equipment data security of intelligent dress type product.
Referring to fig. 2, fig. 2 is a flowchart illustrating a product authentication method according to a second embodiment of the present application.
While embodiments of the product authentication method are provided in the present application, it should be noted that although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown or described herein. The product authentication method is applied to watchbands. The product authentication method comprises the following steps:
step A10, receiving root key configuration data sent by a wearable device main body;
exemplarily, after the watchband is inserted into the wearing device main body, the connector on the watchband can be respectively communicated with the GPIO interface and the GND interface on the MCU in the wearing device main body, so that the IC on the watchband is communicated with the MCU.
Illustratively, the connectors include pogo-pin connectors, dome connectors, wire connectors, and the like.
Illustratively, the IC has the following advantages: no extra power supply is needed, the design is simple, the encryption algorithm is difficult to break, the price is low, the cost performance is high, and the like. Therefore, the product upgrading can be completed on the basis of ensuring that the price is not greatly improved and the original design is changed.
Illustratively, the root key configuration data is data related to the root key, and specifically, the root key configuration data and the root key are subjected to hash operation to obtain the second graph key.
It should be noted that, the wearable device main body does not store the root key, but only stores the root key configuration data and the graph key, and during storage, the root key configuration data is stored in correspondence with the graph key, where the root key configuration data may be composed of random numbers. The root key is stored in the wristband, and, in order to improve the security of the root key, the memory in the wristband is set so as not to be read and written when the root key is stored in the wristband, that is, so as to be called only when the IC in the wristband needs to be used, and not to be read by the wearable device body in a communicative manner.
Note that, although the hash operation is substantially irreversible, that is, root key configuration data cannot be substantially reversely calculated from the graph key, in order to make data in the device more secure, the root key configuration data and the graph key in the wearable device main body are not one set, but multiple sets.
Note that, the conventional watchband has no IC for automatically identifying whether or not the watchband is inserted, and even if a part of the watchband has a function for automatically identifying whether or not the watchband is inserted, the function is realized by providing only a hall sensor, a resistor, or the like in the watchband. This makes the product identification differentiation of the conventional watchband low, and the IC in this embodiment can make the watchband store more configuration information, thereby improving the product identification differentiation.
Step A20, the root key configuration data is operated to obtain first authentication data.
For example, the first authentication data is obtained by performing hash operation on the root key configuration data and the root key, and performing hash operation on the hash operation result and the second graph key again. It will be appreciated that the process of the hash operation is performed by the IC in the watchband.
Step A30, sending the first authentication data to the wearable device main body so that the wearable device main body can authenticate the watchband.
After the first authentication data are sent to the wearable device main body, the wearable device main body can authenticate the watchband based on the first authentication data and the second authentication data. Specifically, if the first authentication data is the same as the second authentication data, it indicates that the root keys used for calculating the first authentication data and the second authentication data are the same root key, and at this time, the wearable device main body may determine that the watchband passes the anti-counterfeiting authentication; if the first authentication data is different from the second authentication data, it is indicated that the root key used for calculating the first authentication data is different from the root key used for calculating the second authentication data, and at this time, the wearable device main body may determine that the watchband does not pass the anti-counterfeiting authentication.
Illustratively, the operating the root key configuration data to obtain first authentication data includes:
step e, acquiring a root key, and performing hash operation on the root key and the root key configuration data to obtain a second graph key;
and f, receiving random data sent by the wearable device main body, and performing hash operation on the second graph key and the random data to obtain first authentication data.
Because the first authentication data is obtained by random data calculation, even if data leakage occurs in the data transmission process, the second graph key cannot be cracked reversely, and the data security of the second graph key is further improved on the basis that the data security is improved by Hash operation.
For example, after the wearable device body determines that the watchband passes the anti-counterfeiting authentication, the method further includes:
and g, sending configuration information to the wearable device main body so that the wearable device main body can switch the working mode to be the working mode corresponding to the configuration information.
Illustratively, the operation mode includes a sport mode, a joint mode, and the like.
It should be noted that, after the working mode is switched, the wearable device main body responds correspondingly, so that the wearable device main body is adapted to the user's requirements in the corresponding working mode. When the working mode is the movement mode, correspondingly, the watchband is the movement watchband, and after the configuration information is read, the movement mode is automatically entered from the current mode (generally, the standby mode), for example, the switching theme is the movement theme; when the working mode is the joint name mode, correspondingly, the watchband is the joint name watchband, and after the configuration information is read, the current mode automatically enters the joint name mode, for example, the theme is switched to be the joint name theme.
It can be understood that the working modes are automatically switched according to the configuration information, so that the switching of the working modes manually performed by a user is avoided, and the convenience of using the wearable equipment by the user is improved.
Compared with the prior art that the intelligent wearable product and the watchband do not have an anti-counterfeiting function, and the equipment data safety of the intelligent wearable product is low, the product authentication method is applied to the watchband, and comprises the following steps: receiving root key configuration data sent by a wearable device main body; performing hash operation on the root key configuration data to obtain first authentication data; and sending the first authentication data to the wearable device main body so that the wearable device main body can authenticate the watchband. This application has realized inserting wearing equipment main part at the watchband after, receive the root key configuration data that wearing equipment main part sent, can understand, this root key configuration data is relevant with the authentication, later to wearing equipment main part send carry out the first authentication data that the hash operation obtained based on root key configuration data, for supply wearing equipment main part to authenticate the watchband, this application carries out data coprocessing together through watchband and wearing equipment main part promptly, thereby realize the anti-fake authentication to the watchband, make intelligence dress type product and watchband possess anti-fake function, and then improve the equipment data security of intelligence dress type product.
