[0022] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0023] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0024] The terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship. In addition, "many" in this article means two or more than two.

[0025] See also Figure 1 , Figure 1 1 is a flowchart of an embodiment of the encrypted communication method of the present application. It should be noted that the disclosed embodiment can be executed by the second communication terminal in the encrypted communication system. Exemplarily, the second communication terminal can specifically include but is not limited to the server. For details, please refer to the embodiment of the encrypted communication system of the present application, which will not be repeated here. Specifically, the disclosed embodiment may include the following steps:

[0026] Step S11: receiving a first password from a first communication terminal.

[0027] In the disclosed embodiment, the first password is generated with the request content and the first parameter as input parameters of the target encryption method, the first parameter represents the time period when the request content is triggered, and the request content is included in several preset contents. As a possible example, the first communication terminal can respond to the request instruction for the preset content, can select the requested preset content as the request content, and obtain the first parameter based on the time period when the request content is triggered, and then use the request content and the first parameter as input parameters of the target encryption method to generate the first password, and send the first password to the communication terminal to realize encrypted communication through password transmission, which can avoid attacks by malicious code / requests as much as possible due to directly passing parameters to the backend and directly inserting the request into the code or database for execution, and the first communication terminal and the communication terminal transmit the password in plain text without decryption processing, which can effectively reduce the resource consumption of the communication terminal and help improve efficiency.

[0028] In an implementation scenario, as described above, the request content is included in several preset contents. Exemplarily, a selection can be made from several preset contents to use the selected preset content as the request content. It should be noted that several preset contents can represent different transaction commodities, that is, through the embodiment of the present disclosure, the first communication terminal can realize commodity trading with the communication terminal through encrypted communication. Exemplarily, the transaction commodity can be a physical commodity, such as clothing, accessories, fresh food, beverages, etc.; or, the transaction commodity can also be a virtual commodity, such as stocks, futures, bonds, funds, etc., and the properties of the transaction commodity are not limited here. In addition, the commodity name of the transaction commodity can be used as the preset content, such as "XX brand milk XX liter", "XX brand XX men's XX size sweater", "XX securities XX fund", etc.; or, the unique code of the transaction commodity can be used as the preset content, such as stock code, fund code, etc. There is no limitation on the representation of the preset content by the commodity name, unique code or other attributes of the transaction commodity, and it can be preferably uniquely identified with different transaction commodities.

[0029] In an implementation scenario, several time periods can be obtained based on the interval duration, and the interval duration can be set according to actual application needs, such as seconds, milliseconds, etc. For example, if the interval duration is set to 1 second, 0 seconds to 1 second is a time period, 1 second to 2 seconds is a time period, 2 seconds to 3 seconds is a time period, and so on. When the interval duration is set to other values, it can be deduced by analogy, and no examples are given here one by one.

[0030] In an implementation scenario, a fixed time of each day can be used as the starting time, and each day can be divided according to the interval length to obtain the time period of each day. For example, 0:0:00 every day can be used as the starting time, and each day can be divided according to 1 second to obtain the time periods of each day: 0:0:0 to 0:0:1, 0:0:1 to 0:0:2, 0:0:2 to 0:0:3..., 23:59:59 to 0:0:0; or, a variable time of each day (such as any time can be randomly selected as the starting time) can be used as the starting time, and then the aforementioned method can be used to divide each day according to the interval length to obtain the time period of each day. In addition, time periods can also be divided into units of weeks, months, quarters, years, etc. For example, a certain moment of each month (such as a fixed moment such as 0:0:00 on the 1st of each month, or a randomly selected moment as the starting moment) can be used as the starting moment, and each month can be divided according to the interval length to obtain the monthly time period. Alternatively, a certain moment of each year (such as a fixed moment such as 0:0:00 on January 1st, or a randomly selected moment as the starting moment) can be used as the starting moment, and each year can be divided according to the interval length to obtain the annual time period.

[0031] In an implementation scenario, the earliest time in the system (e.g., January 1, 1970, 00:00) can also be selected as the starting time, and divided according to the interval length to obtain time periods, such as January 1, 1970, 00:00 to January 1, 1970, 00:01 is a time period, January 1, 1970, 00:01 to January 1, 1970, 00:02 is a time period, January 1, 1970, 00:02 to January 1, 1970, 00:03 is a time period, and so on, until the current time, and examples are not given one by one here.

[0032] In an implementation scenario, the first parameter can be specifically represented by the sequence number of the time period. Taking the division of each day from a fixed time (such as 0 hours, 0 minutes, and 0 seconds) according to the interval duration as an example, the time period from 0 hours, 0 minutes, and 0 seconds to 0 hours, 0 minutes, and 1 second can be represented by the first parameter "1", and the time period from 0 hours, 0 minutes, and 1 second to 0 hours, 0 minutes, and 2 seconds can be represented by the first parameter "2", and so on, and no examples are given here one by one. Or, taking the earliest time in the system (such as 0 hours, 0 minutes, and 0 seconds on January 1, 1970) as the starting time and starting to divide according to the interval duration as an example, the time period from 0 hours, 0 minutes, and 0 seconds on January 1, 1970 to 0 hours, 0 minutes, and 1 second on January 1, 1970 can be represented by the first parameter "1", and the time period from 0 hours, 0 minutes, and 1 second on January 1, 1970 to 0 hours, 0 minutes, and 2 seconds on January 1, 1970 can be represented by the first parameter "2", and so on, until the current time, and no examples are given here one by one.

[0033] In one implementation scenario, the interval duration can be set based on the communication delay between the current communication terminal and the first communication terminal (e.g., the delay can be microsecond delay, millisecond delay, second delay, etc. from small to large), such as the interval duration can be positively correlated with the communication delay, that is, the greater the communication delay, the greater the interval duration, and conversely, the smaller the communication delay, the smaller the interval duration; or, the interval duration can also be set based on the importance level of the encrypted communication between the current communication terminal and the first communication terminal (the importance level of financial commodity transactions is higher than that of ordinary commodity transactions), such as the interval duration can be negatively correlated with the importance level, that is, the higher the importance level, the shorter the interval duration, and conversely, the lower the importance level, the longer the interval duration; or, the interval duration can also be set based on the aforementioned communication delay and importance level, such as the interval duration is positively correlated with the communication delay, and the interval duration is negatively correlated with the importance level.

[0034] In an implementation scenario, the target encryption method can be any encryption algorithm, or it can also be a custom encryption algorithm, and the specific type of the encryption algorithm is not limited here. For example, taking OTP (One Time Password) as the target encryption method, several preset contents can include basketball, football and tennis, and the request content can be football. The first communication end uses the request content "football" and the first parameter representing the time period when the request content "football" is triggered to generate a first password, such as "585446". It should be noted that other encryption methods can also be selected in actual application, which will not be repeated here.

[0035] Step S12: Compare the first password with the password set generated by the communication terminal to obtain a comparison result.

[0036] In the disclosed embodiment, the password set includes a number of second passwords with preset contents. The second password is generated with the preset contents and the second parameter as input parameters of the target encryption method. The second parameters used in different password sets represent different time periods.

[0037] In an implementation scenario, the communication terminal can obtain the second parameter representing the time period in the order of the time periods from earliest to latest, and then use the second parameter and the preset content as the input parameters of the target encryption method to generate the second password of the preset content in the time period represented by the second parameter, so that the password set can be obtained based on the second passwords of several preset contents in the same time period. In the above method, the communication terminal and the first communication terminal use the same encryption method and the same input parameters, which can ensure the accuracy of the request result determined by password comparison later.

[0038] In a specific implementation scenario, in order to improve efficiency, the communication terminal may generate the corresponding second password from the earliest time period within a preset time period (such as half a minute, one minute, etc.) before the current moment. It should be noted that the preset time period may be positively correlated with the communication delay, and the preset time period may be negatively correlated with the importance level. For details, please refer to the setting method of the aforementioned interval time period, which will not be repeated here.

[0039] In a specific implementation scenario, as a possible example, still taking OTP (One Time Password) as the target encryption method as an example, when several preset contents include basketball, football and tennis, according to the time period of the current moment of the communication terminal, a corresponding second password can be generated, such as: the second password "355415" of the preset content "basketball", the second password "156456" of the preset content "tennis", and the second password "585446" of the preset content "football", so as to obtain the password set of the time period of the current moment. Of course, the above example is only a possible example in the actual application process, and does not limit the specific content of the password set, so it is not given one by one here.

[0040] In an implementation scenario, the first communication terminal and the present communication terminal contain the same password generator, and the password generators of the first communication terminal and the present communication terminal both adopt a target encryption method. Exemplarily, the same password generator can be pre-deployed on the first communication terminal and the present communication terminal. In addition, in order to further ensure the accuracy of encrypted communication, the first communication terminal and the present communication terminal can be pre-configured with the same interval duration. Exemplarily, the same interval duration can be configured in the password generators respectively deployed on the first communication terminal and the present communication terminal. In addition, the same starting time can also be configured in the password generators respectively deployed on the first communication terminal and the present communication terminal. It should be noted that the relevant meanings of the interval duration and the starting time, as well as the specific process of dividing the time period according to the starting time and the interval duration, can all be referred to the aforementioned related descriptions, which will not be repeated here.

[0041] In an implementation scenario, the communication terminal can continuously generate password sets corresponding to each time period locally through the above-mentioned method. In this case, it can detect whether the time period represented by the second parameter used in the password set is outside the preset time length before the current moment. If so, the password set can be deleted on the communication terminal. Otherwise, the password set can be retained on the communication terminal. The above-mentioned method determines whether to delete the password set locally by detecting whether the time period represented by the second parameter used in the password set is outside the preset time length before the current moment. On the one hand, it can save the local cache of the communication terminal, and on the other hand, it can also reduce the number of second passwords to be compared with the first password, which helps to improve the comparison efficiency. On the other hand, by appropriately retaining the password set within the preset time length, it can also retain as many second passwords as possible for comparison.

[0042] In a specific implementation scenario, before detecting whether the time period represented by the second parameter used in the password set is outside the preset time length before the current moment, the communication delay between the current communication terminal and the first communication terminal can also be obtained, and the importance level of the encrypted communication between the current communication terminal and the first communication terminal can be obtained, and then the preset time length can be determined at least based on the communication delay and the importance level. As a possible example, the preset time length is positively correlated with the communication delay, and the preset time length is negatively correlated with the importance level. It should be noted that the specific meanings of the communication delay and the importance level can be referred to the above-mentioned related descriptions, and will not be repeated here. The above method first obtains the communication delay between the first communication terminal and the current communication terminal and the importance level of the encrypted communication, and then determines the preset time length based on at least the two, which can help to improve the setting accuracy of the preset time length as much as possible, that is, it can retain as much as possible the second password that is sufficient for comparison, and can delete as much as possible the second password that is not used for comparison because it is too long ahead of the current moment.

[0043] In a specific implementation scenario, taking the preset duration as 3 seconds as an example, if the current time is 0:0:08, the following password sets corresponding to the time period from 0:0:00 to 0:0:1, the password set corresponding to the time period from 0:0:1 to 0:0:2, the password set corresponding to the time period from 0:0:2 to 0:0:3, the password set corresponding to the time period from 0:0:3 to 0:0:4, and the password set from 0:0:4 to 0:0:5 can be deleted, while the following password sets from 0:0:5 to 0:0:6, the password set from 0:0:6 to 0:0:7, and the password set from 0:0:7 to 0:0:8 are retained. Other situations can be deduced by analogy, and no further examples are given here.

[0044] Step S13: Based on the comparison result, determine the request result of the first communication end.

[0045] Specifically, the request result may at least include whether the first communication end successfully requests or fails the request content, and when the request result includes a successful request, the request result also includes the request content, that is, when the communication end determines that the request is successful, it can also determine the request content of the first communication end through password comparison.

[0046] In one implementation scenario, in response to the comparison result including the existence of a second password identical to the first password, it is determined that the request of the first communication terminal is successful, and the preset content corresponding to the second password identical to the first password is determined to be the request content. For example, if the aforementioned request content is "football" as an example, the first password received by this communication terminal is "585446", and the password set generated by this communication terminal includes: the second password "355415" of the preset content "basketball", the second password "156456" of the preset content "tennis", and the second password "585446" of the preset content "football". Since the second password identical to the first password, i.e., the second password "585446" of the preset content "football" is detected through the password comparison, it can be determined that the request of the first communication terminal is successful, and the preset content "football" corresponding to the second password identical to the first password is determined to be the request content of the first communication terminal. Of course, the above example is only a possible example in the actual application process, and does not limit other possible situations, and no examples are given here one by one. In the above method, in response to the comparison result including the existence of a second password identical to the first password, determining that the request of the first communication terminal is successful, and determining the preset content corresponding to the second password identical to the first password as the request content can improve the accuracy of the encryption request.

[0047] In one implementation scenario, as another possible scenario, in response to the comparison result including the absence of a second password identical to the first password, it is determined that the request of the first communication terminal has failed. In the above manner, the attacker cannot generate a valid password when the target encryption method, interval time and preset content are unknown, so when the communication terminal receives the password sent by the attacker, the comparison will not be successful, and the attacker will not be able to request successfully.

[0048] In one implementation scenario, after the first password is compared with the password set generated by the communication terminal and the comparison result is obtained, in response to the comparison result including the existence of a second password identical to the first password, the second password identical to the first password is deleted from the password set generated by the communication terminal. In the above manner, even if the first password of the first communication terminal is intercepted by an attacker and sent to the communication terminal again by the attacker, the communication terminal has deleted the second password identical to the first password, so the comparison cannot be successful again, and the attacker cannot request successfully, thereby preventing replay attacks.

[0049] In one implementation scenario, after determining the request result of the first communication terminal based on the comparison result, the present communication terminal can also feedback the request result to the first communication terminal, such as request success, or request failure, etc., which helps the first communication terminal to promptly understand the confirmation of the request content by the present communication terminal.

[0050] The above scheme receives a first password of the first communication terminal, and the first password is generated with the request content and the first parameter as input parameters of the target encryption method, the first parameter represents the time period when the request content is triggered, and the request content is included in a number of preset contents, and then the first password is compared with the password set generated by the communication terminal to obtain a comparison result, and the password set includes a second password of a number of preset contents, the second password is generated with the preset content and the second parameter as input parameters of the target encryption method, and the second parameters used by different password sets represent different time periods, so as to determine the request result of the first communication terminal based on the comparison result, so on the one hand, there is no need for the communicating parties to exchange keys before formal communication, and there is no need to add an additional third party Verification helps reduce the cost and resource consumption of encrypted communications and improve the security of encrypted communications. Since there is no third party involved, it also helps to reduce the complexity of encrypted communications to a certain extent. On the other hand, since the encryption password for the relevant content is generated by the time factor and the corresponding content as the input parameter of the target encryption method, it can ensure as much as possible that the encryption passwords of different contents under the same time factor are different, and the encryption passwords of the same content under different time factors are also different, that is, only the encryption passwords of the same content under the same time factor are the same. Therefore, the request result can be accurately determined by a simple password comparison, which helps to reduce the complexity of encrypted communications and, to a certain extent, also helps to improve the security of encrypted communications. Therefore, it can reduce the cost, resource consumption and complexity of encrypted communications and improve the security of encrypted communications.

[0051] See also Figure 2 , Figure 2 : is a flowchart of another embodiment of the encrypted communication method of the present application. It should be noted that the embodiment of the present disclosure can be executed by the first communication terminal in the encrypted communication system. Exemplarily, the first communication terminal can specifically include but is not limited to the client. For details, please refer to the embodiment of the encrypted communication system of the present application, which will not be repeated here. Specifically, the embodiment of the present disclosure may include the following steps:

[0052] Step S21: Obtain a first parameter based on the time period when the requested content is triggered.

[0053] In the embodiment of the present disclosure, the request content is included in a number of preset contents, and the details can be referred to the relevant description in the aforementioned disclosed embodiment, which will not be repeated here.

[0054] Step S22: using the request content and the first parameter as input parameters of the target encryption method, generating a first password for the request content in the time period represented by the first parameter.

[0055] For details, please refer to the relevant description in the aforementioned disclosed embodiments, which will not be repeated here.

[0056] Step S23: Send the first password to the second communication terminal.

[0057] In the disclosed embodiment, the second communication terminal compares the first password with the password set generated by the communication terminal to obtain a comparison result, and based on the comparison result, determines the request result of the first communication terminal, and the password set includes a second password with several preset contents, and the second password is generated with the preset contents and the second parameter as the input parameters of the target encryption method, and the second parameters used by different password sets represent different time periods. For details, please refer to the relevant description in the aforementioned disclosed embodiment, which will not be repeated here.

[0058] The above scheme obtains the first parameter based on the time period when the request content is triggered, and the request content is included in several preset contents, and the request content and the first parameter are used as input parameters of the target encryption method to generate a first password for the request content in the time period represented by the first parameter, and then send the first password to the second communication end, and the second communication end compares the first password with the password set generated by the communication end to obtain the comparison result, and determines the request result of the first communication end based on the comparison result, the password set includes the second password of several preset contents, and the second password is generated with the preset content and the second parameter as the input parameters of the target encryption method, and the second parameters used by different password sets represent different time periods, so on the one hand, there is no need for the communicating parties to exchange passwords before formal communication, and on the other hand, the communication process is carried out according to the first parameter. The key does not need to be verified by an additional third party, which helps to reduce the cost and resource consumption of encrypted communication and improve the security of encrypted communication. Since there is no third party involved, it also helps to reduce the complexity of encrypted communication to a certain extent. On the other hand, since the encryption password for the relevant content is generated by the time factor and the corresponding content as the input parameter of the target encryption method, it can ensure as much as possible that the encryption passwords of different contents under the same time factor are different, and the encryption passwords of the same content under different time factors are also different, that is, only the encryption passwords of the same content under the same time factor are the same.

[0059] See also Figure 3 , Figure 3 It is a flowchart of another embodiment of the encryption communication method of the present application.

[0060] Specifically, the following steps may be included:

[0061] Step S31: The first communication end obtains a first parameter based on the time period when the request content is triggered.

[0062] In the disclosed embodiment, the request content is included in several preset contents, which can be specifically referred to in the aforementioned disclosed embodiment, and will not be described in detail here. In addition, as an example, the first communication end can be a client, such as a mobile phone, a tablet computer, etc., and the client can trigger a selection instruction for several preset contents (such as selecting to trade a certain stock, etc.), and use the selected preset content as the request content.

[0063] Step S32: The first communication end uses the request content and the first parameter as input parameters of the target encryption method to generate a first password for the request content in the time period represented by the first parameter.

[0064] For details, please refer to the relevant description in the aforementioned disclosed embodiments, which will not be repeated here.

[0065] Step S33: The first communication terminal sends the first password to the second communication terminal.

[0066] For details, please refer to the relevant description in the aforementioned public embodiment, which will not be repeated here. In addition, as a possible example, the second communication end can be a service end, such as a server, etc., and a password comparison can be implemented on the service end to confirm whether the client's request for the requested content (such as a certain stock) is successful.

[0067] Step S34: The second communication end compares the first password with the password set generated by the communication end to obtain a comparison result.

[0068] In the embodiment of the present disclosure, the password set includes a plurality of second passwords with preset contents, and the second password is generated with the preset contents and the second parameter as the input parameters of the target encryption method, and the second parameters used in different password sets respectively represent different time periods. For details, please refer to the relevant description in the aforementioned disclosed embodiment, which will not be repeated here.

[0069] Step S35: The second communication end determines the request result of the first communication end based on the comparison result.

[0070] For details, please refer to the relevant description in the aforementioned public embodiment, which will not be repeated here. In addition, as a possible example, after the second communication terminal determines the request result of the first communication terminal based on the comparison result, the request result can be returned to the first communication terminal. Exemplarily, the server can determine whether the client's transaction request for a certain stock is successful through the aforementioned password comparison, and return the request result for a certain stock to the client. Of course, the above example is only a possible example in the actual application process, and does not limit other possible scenarios. Examples are not given one by one here.

[0071] The above scheme, on the one hand, does not require the communicating parties to exchange keys before formal communication, and does not require an additional third party to perform verification, which helps to reduce the cost and resource consumption of encrypted communication, and improve the security of encrypted communication. In addition, since there is no third party involved, it also helps to reduce the complexity of encrypted communication to a certain extent. On the other hand, since the encryption password for the relevant content is generated by the time factor and the corresponding content as the input parameter of the target encryption method, it can ensure as much as possible that the encryption passwords of different contents under the same time factor are different, and the encryption passwords of the same content under different time factors are also different, that is, only the encryption passwords of the same content under the same time factor are the same. Therefore, the request result can be accurately determined by a simple password comparison, which helps to reduce the complexity of encrypted communication, and to a certain extent, it also helps to improve the security of encrypted communication. Therefore, it can reduce the cost, resource consumption and complexity of encrypted communication, and improve the security of encrypted communication.

Since there is no third party involved, it also helps to reduce the complexity of encrypted communication to a certain extent. On the other hand, since the encryption password for the relevant content is generated by the time factor and the corresponding content as the input parameter of the target encryption method, it can ensure as much as possible that the encryption passwords of different contents under the same time factor are different, and the encryption passwords of the same content under different time factors are also different, that is, only the encryption passwords of the same content under the same time factor are the same.

The second communication terminal 72 also uses the target encryption method to continuously generate corresponding second passwords for a number of preset contents (such as all stocks) according to the same interval as the first communication terminal 71 locally, so as to combine and obtain a password set for each time period, and compare the first password with the local second password to obtain a comparison result. If it is found that the first password is the same as a local second password, it can be determined that the request of the first communication terminal 71 as a client is successful (such as the request to trade stock X is successful), and it can be determined that the preset content (such as stock X) corresponding to the second password that is the same as the first password is the request content of the first communication terminal 71 as the client, or if it is found that there is no second password that is the same as the first password, it can be determined that the request of the first communication terminal 71 as the client fails (such as the request to trade stock X fails).
