The generator 103 may include a moving part 1031 and a sensing part 1032.
The moving part 1031 may be understood as a component or a combination of components that can be driven by at least one of a button and a reset component to move, and the sensing part 1032 may be understood as a component or a combination of components that can interact with the moving part 1031 to sense and generate electric energy when the moving part moves.
In a specific example, the generator 103 may include a permanent magnet portion, a magnetic conductive portion, and a coil portion, the coil portion may be disposed on the magnetic conductive portion, and the coil portion may generate an induced voltage when the permanent magnet portion and the magnetic conductive portion move relative to each other. The coil part can be regarded as the above mentioned induction part 1032, and the permanent magnet part or the magnetic conductive part can be regarded as the above mentioned movement part 1031, that is: in some examples, the permanent magnet part moves to directly and indirectly transmit with the key and the reset component, and in other examples, the magnetic conduction part moves to directly and indirectly transmit with the key and the reset component. It can be seen that the sensing part 1032 may or may not move with the moving part 1031.

In some embodiments, the reset component 102 can be directly driven to the moving portion 1031, or in other embodiments, the reset component 102 can also be driven to a button or other component, so as to be indirectly driven to the moving portion 1031.
The reset device 102 is configured to: if the button 101 is pressed, then: deformation occurs and a reset acting force overcoming the deformation is generated; if the button 101 generates a rebounding operation, then: the moving part 1031 of the generator 103 is driven by the restoring force.
Furthermore, when the button 101 is pressed down, the movement portion 1031 can be driven to move in a first direction, the reset member 102 can be deformed when the movement portion 1031 moves in the first direction, and can generate a reset acting force to overcome the deformation, and after the acting force for pressing down the button 101 is removed, the reset member 102 can be driven by the reset acting force to move the movement portion 1031 in a second direction, and the button rebounds.
The generator 103 is configured to: if the button 101 is pressed, then: the moving part 1031 of the generator 103 is directly or indirectly driven by the key 101 to generate a first induced voltage in the induction part 1032 of the generator 103, and if the key 101 performs a rebounding manipulation operation, the moving part 1031 of the generator 103 is driven by the reset member 102 to generate a second induced voltage in the generator;
further, the sensing part 1032 is electrically connected to the rectifying module 104 to generate a first induced voltage when the movement part 1031 moves in the first direction, and to generate a second induced voltage when the movement part 1031 moves in the second direction.
The rectifying module 104 is configured to: storing a first electric energy corresponding to the first induced voltage and/or a second electric energy corresponding to the second induced voltage in the energy storage module 105; in a specific example, only the first electrical energy may be stored and/or used, and only the second electrical energy may be stored and/or used.
The energy storage module 105 is configured to: transmitting the stored electrical energy to the voltage output module 106;
the voltage output module 106 is configured to: the transmitted power (the first power and/or the second power) is used for providing a required power supply voltage for the processor 108, the memory 107 and the wireless communication module 109 to power up;
the processor 108 is configured to:
after the processor 108, the memory 107 and the wireless communication module 109 are powered on, a corresponding current control message is generated and sent to the receiving end 2 through the wireless communication module 109 (i.e. the message is sent out by the wireless communication module 109).
Wherein, if from the power generation switch be equipped with reset unit, then: the pressing operation can be the operation of pressing a key, and the rebounding operation can be the operation of removing the pressing action force to rebound the key.
Wherein the current control packet records current control information and the current verification identifier, so that: and the receiving terminal verifies whether the relationship between the current verification identification in the current control message and the stored historical verification identification is matched with a preset transformation rule of the current verification identification, and executes a control event corresponding to the current control information when the relationship is matched with the transformation rule, wherein the historical verification identification is determined according to the verification identification recorded in a control message or a pairing message which is sent to the receiving terminal before the self-generating switch.
The current steering information characterizes at least one of: the self-generating switch; the self-generating switch receives the operated key currently; and the self-generating switch controls the current received operation and control action of the keys.
It can be seen that, since the pressing operation and the rebounding operation are in a pair and continuous manner, rebounding usually occurs after pressing. Furthermore, in the above solution, the current verification identifier may be updated only after the pressing operation or the rebounding operation, or the current verification identifier may be updated only after the pressing operation or the rebounding operation.
In a specific example, the current control information may include a switch identifier, and then the switch identifier may be used to represent the self-generating switch, and the current control information may further include a key value, and then the key value is used to represent the key currently received by the self-generating switch and the control action currently received by the key in the self-generating switch.
The verification mark can be any character or combination of characters which can be suitable for realizing verification, the current verification mark can be understood as being currently sent by the self-generating switch, and the historical verification mark can be understood as being stored by a receiving end before the self-generating switch sends out.
In some examples, the historical verification identifier may be a current verification identifier that is sent to the receiving end (sent with the control message or the pairing message) and stored by the receiving end when the self-power switch has performed the last operation, or determined according to the current verification identifier, and in other examples, the historical verification identifier may also be a current verification identifier that is sent to the receiving end (sent with the control message or the pairing message) and stored by the receiving end when the self-power switch has performed the last specific operation (for example, the operation of pressing down or the operation of rebounding) or determined according to the current verification identifier.
Since the verification identifier is a specific numerical value, the verification identifier can also be described as a serial number, and further, in the example of the embodiment of the present invention, the description of the serial number can be regarded as the description of the verification identifier.
The wireless communication module 109 may be any circuit module capable of implementing wireless communication, and may include at least one of the following: radio frequency module, bluetooth module, Wifi module etc..
In one embodiment, please refer to fig. 3, the self-generating switch 1 further includes a polarity identification module 111; the polarity identification module 111 electrically connects the generator 103 (e.g., its sensing portion 1032) with the processor 108.
The polarity recognition module 111 is electrically connected between the sensing portion 1032 and the processor 108, and configured to feed back a press recognition signal to the processor 108 when the sensing portion 1032 outputs the first sensing voltage, and feed back a rebound recognition signal to the processor 108 when the sensing portion 1032 detects that the second sensing voltage is output.
After the processor, the memory, and the wireless communication module are powered on, the processor 108 is further configured to: the current control action of the key is identified through the polarity identification module 111, and the current control action is determined as a target control, wherein the target control is a designated one of a pressing control action and a rebounding control action.
It can be seen that in the above scheme, a scheme of "the transformation of the authentication identity occurs only after one complete press and rebound" is implemented.
In one embodiment, please refer to fig. 3, the self-generating switch 1 further includes a key identification module 110, and the key identification module 110 is electrically connected to the processor 108;
the processor 108, prior to generating the current control message, may be further configured to:
reading a switch identification characterizing the self-generating switch from the memory;
if the current operation is the operation of pressing down: acquiring current key information through the key identification module, and updating the current key information in the memory;
if the current operation is the springback operation, then: obtaining the stored current key information from the memory;
the current control information is determined based on the switch identifier, the currently generated control action, and the obtained current key information, for example, the switch identifier may be written into the current control packet, or a key value may be determined based on the control action and the current key information, and the key value may be written into the current control packet.
Based on the above description, the processing method and the protocol processing method provided in the embodiments of the present invention may describe the generation, transmission, reception, and processing processes of the current control packet.
Referring to fig. 4, the processing method of the self-generating switch includes:
s301: acquiring current control information and a current verification identifier;
the current manipulation information includes a key value characterizing at least one of: the self-generating switch receives the operated key currently; the self-generating switch is used for controlling the current operation and control action received by the key;
s302: filling the key value and the current verification identification into a key value field and a verification identification field of a payload part of the current control message respectively;
the PayLoad section may refer to "PayLoad" shown in fig. 9 and 10, which may adopt an AD Structure, and the key value field may refer to "key value" shown in fig. 9 and 10; the authentication identification field may refer to a "serial number" shown in fig. 9 and 10; the length of the key value field can be 1 byte, and the length of the verification identification field can be 4 bytes;
s303: signing the filled information of the appointed field in the payload part to obtain current signature information, and filling the current signature information into the signature field of the payload part;
the specified field is at least a partial field in the payload portion other than the signature field; for example, the fields from the length field to the front of the signature field in the payload section; the signature field may refer to "signature" shown in fig. 9 and 10; the signature field may be, for example, 4 bytes in length.
S304: sending the current control message to a receiving end;
through step S304, it is possible to cause: and the receiving end extracts the information filled in the payload part, and executes a control event corresponding to the current control information after verifying that the current signature information and the current verification identifier both pass.
In one embodiment, the process of signing the filled information of the specified field in the payload part in step S303 to obtain current signature information may specifically include:
signing the filled information of the appointed field by using a first key to obtain the current signature information;
the current signature information can be verified based on reference signature information obtained by the receiver re-signing the information filled in the designated field with a second key, where the second key is matched with the first key.
The key can be fixed and unchangeable, and can also be refreshed and changed by a certain method, and the self-generating switch and the receiving end are resynchronized after the refreshing and changing. For example: the key can be changed based on the function value with time as an independent variable, and the function relation corresponding to the first key is matched with the function relation corresponding to the second key.
In a specific example, the key may be a secret string of data, wherein the signature information may be calculated by a predetermined algorithm (e.g., AES algorithm) after combining the plaintext and the key. The plaintext may, for example, control at least part of the content of the message, which may contain the authentication identifier but no signature.
For example: at the self-generating switch, the processor can utilize a first secret key to encrypt the contents of the fields except the signature field in the payload part of the current control message to be sent, so as to obtain signature information, at the receiving end, the receiving end can utilize a second secret key to encrypt the contents of the fields except the signature field in the payload part of the received current control message, so as to obtain the signature information, and the receiving end can utilize the calculated signature information to verify the signature information recorded in the current control message.
In addition, the first key and the second key may be the same, and in other examples, the two keys may also be different.
The anti-counterfeiting function can be realized through the signature information, and the safety is guaranteed.
In one embodiment, referring to fig. 5, step S301 may specifically include:
s3011: whether the current manipulation is received;
if the determination result in step S3011 is yes, step S3012 may be implemented: generating the current manipulation information in response to a current manipulation for the self-generating switch;
if the determination result in step S3011 is no, it may return to step S3011;
s3013: reading the stored current authentication identification;
s3014: whether the current manipulation belongs to a target manipulation;
if the determination result in step S3014 is yes, step S3015 may be implemented: converting the current verification identifier from a first value to a second value according to a preset conversion rule, wherein the first value is different from the second value; the target maneuver includes a press maneuver and/or a rebound maneuver. In a specific example, the target manipulation may be determined by one of pressing and rebounding.
If the determination result in step S3014 is no, the process may return to step S3011.
The scheme of 'the change of the verification identifier only occurs after one complete press and rebound' can also play a role in saving electric energy. For example: if the sequence number (i.e. the current authentication identity) is updated only at the time of the rebound: when the serial number is pressed down, the serial number (namely the current verification identifier) does not need to be updated, and especially the energy consumption for writing the updated serial number into the memory can be saved.
Moreover, when the sequence numbers (namely the current verification identifiers) corresponding to the pressed control actions and the rebounded control actions are the same, the receiving end can be simpler to perform message deduplication according to the sequence numbers.
In a further example, the target manipulation is a rebound manipulation, and in other examples, the target manipulation may also be a press manipulation.
When a user presses a key of the self-generating switch, the user usually wants to obtain feedback of the control effect immediately. Furthermore, if the sequence number is updated only during rebound (i.e. the target maneuver is a maneuver that rebounds), all of the power during the depression can be used for other tasks, in particular to send a signal, without expending power to update the sequence number.
In one embodiment, the transformation rule includes at least one of:
accumulating a first reference value on the basis of said first value to obtain said second value;
subtracting a second reference value from the first value to obtain a second value;
multiplying a third reference value by the first value to obtain the second value;
dividing the first value by a fourth reference value to obtain the second value.
The accumulation, subtraction, multiplication, division and the like can be calculated by adopting decimal calculation and can also be calculated by adopting binary system or other binary systems. The first, second, third and fourth reference values may be fixed values or variable values, and their signs are usually the same and are not zero, e.g. positive numbers.
Taking the accumulated first reference value as an example, the first reference value used for accumulation may be a positive number that varies within a certain range, and further for example, the accumulated value may vary regularly, for example: if the cycle changes from accumulation 1, accumulation 2, and accumulation 3, then: the k-th transformation is realized by accumulating 1, the k + 1-th transformation is realized by accumulating 2, the k + 2-th transformation is realized by accumulating 3, and the k + 3-th transformation is realized by accumulating 1 again.
Corresponding to the above various cases, the processing method at the receiving end may include:
if the transformation rule is: accumulating a first reference value on the basis of said first value to obtain said second value, then: when the receiving end verifies whether the current verification identification is matched with the historical verification identification, the receiving end can verify whether the current verification identification is larger than the historical verification identification, or: verifying whether the current verification identification is larger than the historical verification identification or not, wherein the difference value of the current verification identification and the historical verification identification is matched with the first reference value;
if the transformation rule is: subtracting a second reference value from the first value to obtain a second value; then: when the receiving end verifies whether the current verification identification is matched with the historical verification identification, the receiving end can verify whether the current verification identification is smaller than the historical verification identification, or: verifying whether the current verification identification is smaller than the historical verification identification or not, wherein the difference value of the current verification identification and the historical verification identification is matched with the second reference value;
if the transformation rule is: multiplying a third reference value by the first value to obtain the second value; then: when the receiving end verifies whether the current verification identification is matched with the historical verification identification, the receiving end can verify whether the current verification identification is larger than the historical verification identification, or: verifying whether the current verification identification is larger than the historical verification identification or not, wherein the ratio of the current verification identification to the historical verification identification is matched with the third reference value;
if the transformation rule is: dividing said first value by a fourth reference value to obtain said second value; then: when the receiving end verifies whether the current verification identification is matched with the historical verification identification, whether the current verification identification is smaller than the historical verification identification can be verified, or: and verifying whether the current verification identification is smaller than the historical verification identification or not, wherein the ratio of the current verification identification to the historical verification identification is matched with the fourth reference value.
In the above scheme, by comparing the difference value with the first numerical value and the second numerical value and comparing the ratio value with the third numerical value and the fourth numerical value, it can be verified whether the comparison between the current verification identifier and the historical verification identifier is increased or decreased, and the change amplitude can also be verified, so that an attacker can perform exhaustive attack by using the numerical value which is larger (or smaller) than the current numerical value, and the security is further improved.
The difference value is matched with the first reference value and the second reference value, which can be understood as the same value, or the difference value is smaller than a certain threshold value, and the ratio value is matched with the third reference value and the fourth reference value, which can be understood as the same value, or the difference value is smaller than a certain threshold value.
In a specific example, the self-generating switch carries a serial number (i.e., a verification identifier), the serial number is automatically increased (or decreased) when the switch is pressed each time, and the serial number is automatically increased once after a complete press and rebound operation; the message carries information representing pressing/bouncing (it can be understood that the control information can represent control action).
Specifically, the self-generating switch rebounds after being pressed down each time, and the generator operates to generate electricity when being pressed down and rebounded, so that power is supplied to a back-end circuit (such as a processor, a wireless communication module, a memory and the like). The back-end circuit can identify whether the control action is a pressing control action or a rebounding control action through the polarity identification module.
If the control action is a pressing action, the serial number (namely the stored verification identification) is read from the memory, then the serial number is increased by itself (which can be understood as the transformation), and then the key information is read to generate the control message. And writing the serial number and the key information back to the memory, reading the serial number and the key information when the serial number and the key information are rebounded, and then sending the message. The order of writing back the memory and sending the message can be interchanged.
If the control is the rebound control, the serial number is directly read from the memory without self-increment (namely, the conversion is not needed to be implemented), and the key information is also directly read from the memory (rather than reading the feedback signal of the switching device).
To facilitate the description of the role of signature information and authentication identifiers (e.g., serial numbers), several concepts are first cleaned up as follows:
copy attack:
it can be understood that: an attacker first captures a message of a legal switch and then sends the message out without moving the message. By verifying the use of the identification, it is possible to effectively protect against copying attacks, such as: the receiving end stores the serial number (i.e. the verification identifier) of the last received message, and after receiving a new message, the receiving end continues to check the serial number even if the signature information is verified to be legal: the disallowed sequence number is the sequence number that has been received before the press or bounce, but is a sequence number that is larger than before and falls within a window (all, or a sliding window large enough).
Forgery attack:
it can be understood that: the attacker can operate a real device (e.g., an autonomous switch) that can issue a control message and then actively add 1 to the serial number (if the serial number is plaintext) to reconstruct the message.
Through the signature information, forgery attacks can be effectively prevented, and the signature information is calculated by the key according to the previous message content (if the serial number is plaintext). The self-generating switch is encrypted by a key, the receiving end calculates once by the key, and if the key is obtained, the message of the transmitting end is considered to be legal.
When using the authentication identification (e.g., serial number) and signature information, it may be possible, for example:
in the pairing process, the receiving end and the self-generating switch synchronize serial numbers; the serial number can not be verified in the pairing process, and the signature information can still be verified, namely the pairing process only considers anti-counterfeiting and does not consider anti-copying. Of course, the signature information can be verified;
in normal operation, on the one hand, the signature information is verified, and on the other hand, the serial number is verified, and only the verification is allowed to be larger (or smaller) than the previous serial number. If further strict verification is to be performed, the sequence number is required to be larger than the previous sequence number and to fall within a window (which may be embodied as, for example, the aforementioned first reference value, second reference value, third reference value, fourth reference value). Window-based verification can effectively cope with exhaustive attacks, such as: an attacker can perform an exhaustive attack with a sequence number larger than the current sequence number if no window is required.
In one embodiment, the authentication identifier (e.g., sequence number) itself is also converted before transmission, and an attacker cannot obtain the current sequence number. And further: the current verification identifier recorded in the current control message is a converted current verification identifier, wherein the conversion mode is a first data conversion mode, namely: the current verification identifier recorded in the current control message is the current verification identifier converted by the first data conversion mode;
the current verification identifier verified by the receiving end is obtained by reversely converting the converted current verification identifier, wherein the reverse conversion mode is a second data conversion mode, and the first data conversion mode and the second data conversion mode are opposite data conversion modes, that is: the current verification identification verified by the receiving end is obtained by carrying out reverse conversion on the converted current verification identification in a second data conversion mode.
The first data conversion method and the second data conversion method are opposite conversion methods, and any conversion method is adopted without departing from the scope of the embodiment of the invention.
