Specifically, a secure communication method specifically includes the following steps:
step S100, the intelligent mobile terminal receives the issuing instruction and records the instruction issuing time of the issuing instruction.
Specifically, fig. 2 shows a flowchart of recording the instruction issue timing.
The intelligent mobile terminal receives the issuing instruction and records the instruction issuing time of the issuing instruction, and the intelligent mobile terminal specifically comprises the following steps:
step S101, an intelligent mobile terminal receives a issuing instruction and analyzes whether the issuing instruction needs to be sent to wearable equipment or not;
step S102, if the intelligent mobile terminal determines that the issuing instruction needs to be sent to the wearable equipment, the instruction issuing time of the issuing instruction is recorded.
In the embodiment of the invention, the intelligent mobile terminal capable of establishing communication connection with the user wearable equipment is generally a smart phone, and it can be understood that the intelligent mobile terminal is provided with the client APP corresponding to the wearable equipment, and the establishment of the communication connection between the intelligent terminal equipment and the wearable equipment refers to the establishment of the communication connection between the client APP installed in the intelligent terminal equipment and the wearable equipment;
after a user holding the intelligent mobile terminal issues an instruction on the intelligent mobile terminal, the intelligent mobile terminal analyzes the issuing instruction and judges whether the issuing instruction is required to be matched with the wearable equipment, when the wearable equipment is required to be matched, the intelligent mobile terminal is determined to be required to send the issuing instruction to the wearable equipment, and communication connection between the intelligent mobile terminal and the wearable equipment is required to be established, so that data can be mutually transferred between the intelligent mobile terminal and the wearable equipment, and the intelligent mobile terminal records and stores the instruction issuing time of the issuing instruction when the issuing instruction is determined to be required to be sent to the wearable equipment.
Further, the secure communication method further includes the steps of:
Step S200, the intelligent mobile terminal and the wearable equipment respectively generate a first authentication secret key and a second authentication secret key according to the instruction issuing time;
the intelligent mobile terminal and the wearable device are respectively provided with a first data model and a second data model, the first data model and the second data model are respectively provided with the same ciphertext table, the ciphertext table comprises a plurality of preset instruction issuing time and a plurality of authentication keys, each preset instruction issuing time corresponds to a unique authentication key, preferably, the instruction issuing time and the preset instruction issuing time received by the intelligent mobile terminal and the wearable device are accurate to seconds, the specific format is XXXX month XX minute XX seconds, for example, the ciphertext table comprises one preset instruction issuing time 2023, 1 point, 1 minute, 1 second, the authentication key corresponding to the moment is 123456, the ciphertext table comprises another preset instruction issuing time 2023, 1 point, 1 minute, 2 seconds, and the authentication key corresponding to the moment is 654321.
In particular, fig. 3 shows a flow chart of generating a first authentication key and a second authentication key.
The intelligent mobile terminal and the wearable device respectively generate a first authentication secret key and a second authentication secret key according to the instruction issuing time, and specifically comprise the following steps:
Step S201, the intelligent mobile terminal inputs the instruction issuing time into a first data model, and matches a first authentication key corresponding to the instruction issuing time in a ciphertext table of the first data model;
step S202, the intelligent mobile terminal sends the first authentication secret key and the instruction issuing time to the wearable equipment;
in step S203, the wearable device inputs the instruction issue time to the second data model, and matches a second authentication key corresponding to the instruction issue time in a ciphertext table of the second data model.
In the embodiment of the invention, the instruction issuing time is a key premise that the intelligent mobile terminal and the wearable device acquire the first authentication secret key and the second authentication secret key, and because the instruction issuing time is real-time, the first authentication secret key and the second authentication secret key generated by the intelligent mobile terminal and the wearable device have instantaneity, so the first authentication secret key and the second authentication secret key cannot be obtained by being cracked by external devices and personnel before specific contents are determined, and further, the instruction issuing time is random and the random uncertainty is based on the time for using the intelligent mobile terminal and the wearable device for users, so that the external devices and personnel are difficult to obtain the generation rules of the first authentication secret key and the second authentication secret key when the intelligent mobile terminal and the wearable device generate the first authentication secret key and the second authentication secret key;
When the intelligent mobile terminal determines that the instruction issuing needs to be completed by the wearable device, the intelligent mobile terminal firstly inputs the recorded and stored instruction issuing time into a first data model, and matches a first authentication secret key corresponding to the instruction issuing time in a ciphertext table of the first data model, namely, finds out a first authentication secret key bound to a preset instruction issuing time identical to the instruction issuing time, then the intelligent mobile terminal sends the instruction issuing time and the first authentication secret key to the wearable device together, after receiving the instruction issuing time, the wearable device inputs the instruction issuing time into a second data model, and matches a second authentication secret key corresponding to the instruction issuing time in a ciphertext table of the second data model, namely, finds out a second authentication secret key bound to the preset instruction issuing time identical to the instruction issuing time, so that the intelligent mobile terminal and the wearable device respectively generate the first authentication secret key and the second authentication secret key.
Further, the secure communication method further includes the steps of:
step S300, the wearable device compares the first authentication key with the second authentication key.
And step S400, when the wearable device determines that the first authentication secret key and the second authentication secret key are different, generating verification failure information, and sending the verification failure information to the intelligent mobile terminal.
In the embodiment of the invention, after the intelligent mobile terminal and the wearable device respectively generate the first authentication secret key and the second authentication secret key, the wearable device can compare the first authentication secret key with the second authentication secret key and judge whether the wearable device has the establishment condition of the secure communication channel according to the comparison result, when the wearable device determines that the first authentication secret key and the second authentication secret key are different, verification failure information is generated and sent to the intelligent mobile terminal, the wearable device determines that multiple conditions exist in the first authentication secret key and the second authentication secret key, wherein the conditions exist that the external device and a user invade the wearable device through the illegal authentication secret key to attempt to establish the communication channel exist, for example, when the wearable device receives a request for establishing the communication channel, and does not recognize the issuing moment of an instruction in the request information, the communication channel is indicated that the request for establishing the secure communication channel is from the external device, and the user illegal invasion, when the conditions occur, the wearable device directly refuses to establish the secure communication channel, and then the wearable device generates verification failure information and sends the verification failure information to the intelligent mobile terminal, so that the external device can directly invade the wearable device through the secure communication channel in order to prevent the external device from invading the external device.
Further, the secure communication method further includes the steps of:
and step S500, when the wearable device determines that the first authentication secret key and the second authentication secret key are the same, generating two-way authentication passing information and sending the two-way authentication passing information to the intelligent mobile terminal.
Step S600, the intelligent mobile terminal analyzes the two-way authentication passing information and judges whether to establish a secure communication channel with the wearable device.
In the embodiment of the invention, when the wearable device determines that the first authentication secret key and the second authentication secret key are the same, the bidirectional authentication passing information is generated and sent to the intelligent mobile terminal, but the intelligent mobile terminal cannot determine that the intelligent mobile terminal and the wearable device are in a secure communication environment only by obtaining the bidirectional authentication passing information because the following conditions exist: the external equipment and the user forge the two-way authentication passing information and directly invade the intelligent mobile terminal through the two-way authentication passing information to attempt to establish a communication channel. Therefore, in the application, after the intelligent mobile terminal receives the bidirectional authentication passing information from the wearable device, the bidirectional authentication passing information should be subjected to auditing processing to determine whether the bidirectional authentication passing information is from the wearable device mutually bound with the intelligent mobile terminal, and whether the bidirectional authentication passing information meets the security auditing requirement of the application.
In particular, fig. 4 shows a flow chart of determining whether to establish a secure communication channel with a wearable device.
The intelligent mobile terminal analyzes the two-way authentication passing information and judges whether to establish a secure communication channel with the wearable device or not, and the method specifically comprises the following steps:
step S601, the intelligent mobile terminal analyzes the two-way authentication passing information and judges whether the two-way authentication passing information contains the same content of the first authentication key and the second authentication key;
step S601, when the intelligent mobile terminal determines that the bidirectional authentication passing information does not contain the same content of the first authentication secret key and the second authentication secret key, the intelligent mobile terminal refuses to establish a secure communication channel with the wearable device;
in step S603, when the intelligent mobile terminal determines that the mutual authentication passing information includes the same content as the first authentication key and the second authentication key, a secure communication channel is established with the wearable device.
Specifically, fig. 5 shows a flowchart for determining whether the formats of the first authentication key and the second authentication key are the same as the preset key format.
When the intelligent mobile terminal determines that the mutual authentication passing information contains the same content as the first authentication key and the second authentication key, the method for establishing the secure communication channel with the wearable device specifically comprises the following steps:
Step S6031, when the intelligent mobile terminal determines that the bidirectional authentication passing information contains the same content as the first authentication key and the second authentication key, the first authentication key and the second authentication key are extracted;
step S6032, the intelligent mobile terminal judges whether the formats of the first authentication secret key and the second authentication secret key are the same as the preset secret key format;
step S6033, if the intelligent mobile terminal judges that the formats of the first authentication secret key and the second authentication secret key are the same as the preset secret key format, a secure communication channel is established with the wearable device;
in step S6034, if the intelligent mobile terminal determines that the formats of the first authentication key and the second authentication key are different from the preset key format, the intelligent mobile terminal refuses to establish the secure communication channel with the wearable device.
In the embodiment of the invention, when the wearable device generates the bidirectional authentication passing information, the bidirectional authentication passing information contains the specific content of the first authentication secret key, the specific content of the second authentication secret key and the same content of the first authentication secret key and the second authentication secret key, after the intelligent mobile terminal receives the bidirectional authentication passing information from the wearable device, the intelligent mobile terminal decodes the bidirectional authentication passing information in a near way and determines whether the bidirectional authentication passing information contains the specific content of the first authentication secret key, the specific content of the second authentication secret key and the same content of the second authentication secret key, if the bidirectional authentication passing information contains the specific content of the first authentication secret key, the specific content of the second authentication secret key and the same content of the second authentication secret key, the bidirectional authentication passing information is from the wearable device which is mutually bound with the intelligent mobile terminal, and accords with the rule of the establishment method of the secure communication channel, and if the intelligent mobile terminal does not find the specific content of the first authentication secret key, the specific content of the second authentication secret key and the same content of the second authentication secret key in the bidirectional authentication passing information, or if the specific content of the second authentication secret key and the first authentication secret key and the same content of the second authentication secret key are not found in the bidirectional authentication passing information, the mobile terminal directly passes through the secure communication channel, and the secure communication channel is completely established by the external communication channel;
It can be understood that, in order to improve the security degree of the establishment of the communication channel, when the intelligent mobile terminal determines that the bidirectional authentication passing information contains the specific content of the first authentication key, the specific content of the second authentication key and the content identical to the specific content of the first authentication key and the second authentication key, the intelligent mobile terminal then examines the formats of the first authentication key and the second authentication key, and determines whether the formats of the first authentication key and the second authentication key are identical to the preset key format of the intelligent mobile terminal, the formats are mainly the character specification of the authentication key, thereby maximally ensuring the true reliability of the bidirectional authentication passing information and improving the security of the established secure communication channel;
through the technical scheme, when the secure communication channel is established between the intelligent mobile terminal and the wearable equipment, the authentication secret key generated by the two parties can have instantaneity and randomness, so that the authentication secret key cannot be obtained by external equipment and personnel in a cracking way before the specific content is determined, and the generation rule of the authentication secret key is difficult to obtain by the external equipment and the personnel, thereby greatly improving the security degree of the communication channel established by the secure communication method.
Further, fig. 6 shows an application architecture diagram of the platform according to an embodiment of the present invention.
In another preferred embodiment of the present invention, a secure communication platform includes:
the instruction issue time recording unit 100 is configured to receive an issue instruction from the intelligent mobile terminal, and record an instruction issue time of the issue instruction.
Specifically, fig. 7 shows a block diagram of the configuration of the instruction issue timing recording unit 100.
The instruction issue time recording unit 100 specifically includes:
the issuing instruction analysis module 101 is configured to receive an issuing instruction from an intelligent mobile terminal, and analyze whether the issuing instruction needs to be sent to a wearable device;
the instruction issue time recording module 102 is configured to record an instruction issue time of the issue instruction if the intelligent mobile terminal determines that the issue instruction needs to be sent to the wearable device.
In the embodiment of the invention, the intelligent mobile terminal capable of establishing communication connection with the user wearable equipment is generally a smart phone, and it can be understood that the intelligent mobile terminal is provided with the client APP corresponding to the wearable equipment, and the establishment of the communication connection between the intelligent terminal equipment and the wearable equipment refers to the establishment of the communication connection between the client APP installed in the intelligent terminal equipment and the wearable equipment;
After a user holding the intelligent mobile terminal issues an instruction on the intelligent mobile terminal, the intelligent mobile terminal analyzes the issue instruction and judges whether the issue instruction needs to be completed by the wearable device, when the wearable device needs to be completed by the cooperation, the issue instruction analysis module 101 determines that the intelligent mobile terminal needs to send the issue instruction to the wearable device, and needs to establish communication connection between the intelligent mobile terminal and the wearable device, so that data can be mutually transferred between the intelligent mobile terminal and the wearable device, and the instruction issue time recording module 102 records and stores the instruction issue time of the issue instruction when the issue instruction needs to be sent to the wearable device.
Further, the secure communication platform further comprises:
the first authentication key and second authentication key generating unit 200 is configured to generate a first authentication key and a second authentication key according to the instruction issuing time by the smart mobile terminal and the wearable device, respectively.
Specifically, fig. 8 shows a block diagram of the first authentication key and the second authentication key generation unit 200.
The first authentication key and the second authentication key generating unit 200 specifically include:
The first authentication key generation module 201 is configured to input the instruction issue time into the first data model by using the intelligent mobile terminal, and match a first authentication key corresponding to the instruction issue time in a ciphertext table of the first data model;
a first authentication key and instruction issue time sending module 202, configured to send, by an intelligent mobile terminal, both the first authentication key and the instruction issue time to a wearable device;
the second authentication key generation module 203 is configured to input the instruction issue time to the second data model by using the wearable device, and match a second authentication key corresponding to the instruction issue time in a ciphertext table of the second data model.
In the embodiment of the invention, a first data model and a second data model are respectively set in the intelligent mobile terminal and the wearable equipment, the first data model and the second data model are both stored with the same ciphertext table, the ciphertext table comprises a plurality of preset instruction issuing time and a plurality of authentication keys, each preset instruction issuing time corresponds to a unique authentication key, preferably, the instruction issuing time and the preset instruction issuing time received by the intelligent mobile terminal and the wearable equipment are accurate to seconds, the specific format is XXXX year XX month XX day XX minute XX seconds, for example, the ciphertext table comprises one preset instruction issuing time 2023, 1 day 1 minute 1 second, the authentication key corresponding to the time is 123456, the ciphertext table comprises another preset instruction issuing time 2023, 1 month 1 day 1 minute 2 seconds, and the authentication key corresponding to the time is 654321;
The instruction issuing time is a key premise that the intelligent mobile terminal and the wearable device acquire the first authentication secret key and the second authentication secret key, and because the instruction issuing time is real-time, the first authentication secret key and the second authentication secret key generated by the intelligent mobile terminal and the wearable device have instantaneity, so that the first authentication secret key and the second authentication secret key cannot be obtained by being cracked by external devices and personnel before specific contents are determined, and further, the instruction issuing time is random and is based on uncertainty of time for using the intelligent mobile terminal and the wearable device for a user, and therefore, when the intelligent mobile terminal and the wearable device generate the first authentication secret key and the second authentication secret key, the external devices and the personnel are difficult to obtain a generation rule;
when the intelligent mobile terminal determines that the instruction issuing needs to be matched with the wearable device, the first authentication key generation module 201 firstly inputs the instruction issuing time recorded and stored in the first data model, matches a first authentication key corresponding to the instruction issuing time in a ciphertext table of the first data model, namely finds a first authentication key bound with a preset instruction issuing time identical to the instruction issuing time, then the first authentication key and the instruction issuing time sending module 202 send the instruction issuing time and the first authentication key to the wearable device together, the wearable device receives the instruction issuing time and inputs the instruction issuing time into the second data model, and the second authentication key generation module 203 matches a second authentication key corresponding to the instruction issuing time in a ciphertext table of the second data model, namely finds a second authentication key bound with the preset instruction issuing time identical to the instruction issuing time, so that the intelligent mobile terminal and the wearable device generate the first authentication key and the second authentication key respectively.
Further, the secure communication platform further comprises:
a first authentication key and second authentication key comparing unit 300, configured to compare the first authentication key with the second authentication key by using the wearable device;
and the authentication failure information sending unit 400 is configured to generate authentication failure information and send the authentication failure information to the intelligent mobile terminal when the wearable device determines that the first authentication key and the second authentication key are different.
In the embodiment of the present invention, after the smart mobile terminal and the wearable device respectively generate the first authentication key and the second authentication key, the first authentication key and the second authentication key comparing unit 300 may compare the first authentication key with the second authentication key, and judge whether there is an establishment condition of the secure communication channel according to the comparison result, when the wearable device determines that the first authentication key is different from the second authentication key, the authentication failure information sending unit 400 generates authentication failure information and sends the authentication failure information to the smart mobile terminal, the wearable device determines that there are multiple situations in which the first authentication key and the second authentication key are different, and an external device and a user invade the wearable device through an illegal authentication key to attempt to establish the communication channel.
Further, the secure communication platform further comprises:
the mutual authentication passing information sending unit 500 is configured to generate mutual authentication passing information when the wearable device determines that the first authentication key and the second authentication key are the same, and send the mutual authentication passing information to the intelligent mobile terminal;
the secure communication channel establishing unit 600 is configured to parse the bidirectional authentication passing information and determine whether to establish a secure communication channel with the wearable device.
In the embodiment of the present invention, when the wearable device determines that the first authentication key and the second authentication key are the same, mutual authentication passing information is generated, and the mutual authentication passing information is transmitted to the intelligent mobile terminal by the mutual authentication passing information transmitting unit 500, but the intelligent mobile terminal cannot determine that the intelligent mobile terminal and the wearable device are in a secure communication environment only by obtaining the mutual authentication passing information, because the following situation exists: the external equipment and the user forge the two-way authentication passing information and directly invade the intelligent mobile terminal through the two-way authentication passing information to attempt to establish a communication channel. Therefore, in the present application, after the smart mobile terminal receives the mutual authentication passing information from the wearable device, the secure communication channel establishing unit 600 should further perform an audit process on the mutual authentication passing information to determine whether the mutual authentication passing information is from the wearable device mutually bound with the smart mobile terminal, and determine whether the mutual authentication passing information meets the security audit requirement of the present application.
Specifically, fig. 9 shows a block diagram of the structure of the secure communication channel establishing unit 600.
The secure communication channel establishing unit 600 specifically includes:
the mutual authentication passing information analysis module 601 is configured to analyze the mutual authentication passing information and determine whether the mutual authentication passing information contains the same content as the first authentication key and the second authentication key;
a secure communication channel rejection establishing module 602, configured to reject establishing a secure communication channel with the wearable device when the intelligent mobile terminal determines that the bidirectional authentication passing information does not include the same content as the first authentication key and the second authentication key;
a secure communication channel establishment module 603, configured to establish a secure communication channel with the wearable device when the smart mobile terminal determines that the bidirectional authentication passing information contains the same content as the first authentication key and the second authentication key
In the embodiment of the present invention, when the wearable device generates the bidirectional authentication passing information, the bidirectional authentication passing information should be made to include the specific content of the first authentication key, the specific content of the second authentication key and the same content of the two, after the intelligent mobile terminal receives the bidirectional authentication passing information from the wearable device, the bidirectional authentication passing information analysis module 601 interprets the bidirectional authentication passing information in a short time, and determines whether the bidirectional authentication passing information includes the specific content of the first authentication key, the specific content of the second authentication key and the same content of the two, if the bidirectional authentication passing information includes the specific content of the first authentication key, the specific content of the second authentication key and the same content of the two, it is explained that the bidirectional authentication passing information comes from the wearable device mutually bound with the intelligent mobile terminal and accords with the rule of the method for establishing a secure communication channel, and if the intelligent mobile terminal does not find the specific content of the first authentication key, the specific content of the second authentication key and the same content of the second authentication key in the bidirectional authentication passing information, or if the specific content of the two authentication passing information is not found in the bidirectional authentication passing information, or if the specific content of the second authentication key and the same content of the first authentication key and the wearable device are not found in the secure communication channel, the secure communication channel is established between the two mobile terminal and the wearable device, and the external communication channel is completely rejected, the intelligent mobile terminal is directly invaded by the information through the bidirectional authentication to successfully establish a communication channel;
It can be understood that, in order to improve the security degree of the establishment of the communication channel, when the intelligent mobile terminal determines that the bidirectional authentication passing information contains the specific content of the first authentication key, the specific content of the second authentication key and the content identical to the specific content of the first authentication key and the second authentication key, the intelligent mobile terminal then examines the formats of the first authentication key and the second authentication key, and determines whether the formats of the first authentication key and the second authentication key are identical to the preset key format of the intelligent mobile terminal, the formats are mainly the character specification of the authentication key, thereby maximally ensuring the true reliability of the bidirectional authentication passing information and improving the security of the established secure communication channel.
