Fig. 2 is a schematic flowchart of a communication encryption method according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
step S202, obtaining the target bandwidth frequency of the communication sending end.
In this step, the target bandwidth frequency may be a value that fluctuates at any time, rather than a fixed bandwidth frequency value. The communication sending end can be provided with a three-party interface for receiving the communication content of the communication sending end and monitoring the target bandwidth frequency of the communication sending end.
Step S204, the target bandwidth frequency and the communication content are encrypted to obtain encrypted transmission data.
In this step, the target bandwidth frequency and the communication content are encrypted by the same encryption method, and the ciphertext of the target bandwidth frequency and the ciphertext of the communication content can be obtained respectively, and then the two ciphertexts are combined to obtain encrypted transmission data.
Step S206, the target bandwidth frequency and the encrypted transmission data are sent to a communication receiving end.
In this step, the target bandwidth frequency is sent to the communication receiving end, which can help the communication receiving end to solve the communication key and the communication receiving end to decrypt the encrypted transmission data after taking the key, so as to obtain the communication content that the communication sending end wants to transmit. Optionally, the communication receiving end may first determine the encrypted target bandwidth frequency from the encrypted transmission data according to a pre-agreed encrypted transmission data format, then perform inverse operation of encryption based on the encrypted target bandwidth frequency to solve the key, and after the communication receiving end takes the key, the communication receiving end may decrypt the encrypted transmission data to obtain the communication content.
Through the steps, the purpose of encrypting by adopting different keys in each communication is achieved, so that the technical effects of improving the safety and reliability of communication encryption are achieved, and the technical problem that the communication is unsafe due to the fact that the keys are easy to leak in the communication process is solved. Because the target bandwidth frequency is fluctuant, the keys used by the two communication parties each time when encrypting the communication content are different, the communication content is difficult to obtain by the outside through a brute force cracking method, and the communication safety is guaranteed.
As an alternative embodiment, the target bandwidth frequency and the communication content are encrypted to obtain encrypted transmission data, and a predetermined encryption constant may be first obtained; and then encrypting the encryption constant, the target bandwidth frequency and the communication content to obtain encrypted transmission data.
Alternatively, the encryption constant may be predetermined by the communication transmitting end and the communication receiving end, for example, a universal constant may be used as the encryption constant. The communication sending end can firstly calculate the encryption constant and the target bandwidth frequency, and then encrypt the encryption constant and the target bandwidth frequency by adopting an encryption algorithm. And during communication, only the target bandwidth frequency is transmitted to the communication receiving end, and the encryption constant is not transmitted. Since the communication receiving end knows the agreed encryption constant in advance, the communication receiving end can obtain the key through inverse operation, but the communication content intercepted by the interceptor does not include the encryption constant, so the key cannot be cracked. In the embodiment, the complicated encryption constant is selected, so that the cracking difficulty can be improved, and the communication safety can be improved.
As an alternative embodiment, the target bandwidth frequency and the communication content are encrypted to obtain encrypted transmission data, and the following method is used: respectively carrying out modulus taking on the target bandwidth frequency and the communication content to obtain a plurality of groups of modulus values; and converting the plurality of groups of module values into encrypted transmission data in a character string format. Optionally, in the process of converting the multiple sets of modulus values into the encrypted transmission data in the String format, the multiple sets of modulus values may be multiplied by the target bandwidth frequency to convert into a byte array, then the byte array is converted into a String, and the formed String is transmitted as an encryption result, that is, the encrypted transmission data, so as to further improve the security of communication.
As an alternative embodiment, the following steps may be adopted to obtain the target bandwidth frequency of the communication sending end: acquiring a preset bandwidth frequency and an average bandwidth frequency of a communication sending end, wherein a target bandwidth frequency comprises the average bandwidth frequency; and comparing the preset bandwidth frequency with the average bandwidth frequency to obtain a comparison result, and acquiring one of the uplink bandwidth frequency and the downlink bandwidth frequency of the communication sending end according to the comparison result, wherein the target bandwidth frequency comprises the uplink bandwidth frequency and the downlink bandwidth frequency. As an optional embodiment, according to the comparison result, a first bandwidth frequency of the communication sending end is obtained, and the uplink bandwidth frequency of the communication sending end may be obtained under the condition that the predetermined bandwidth frequency is greater than the average bandwidth frequency; and under the condition that the preset bandwidth frequency is less than the average bandwidth frequency, acquiring the downlink bandwidth frequency of the communication sending end.
In this optional embodiment, the average bandwidth frequency may be an average value of a current uplink bandwidth frequency and a current downlink bandwidth frequency of the communication sending end, or may be an average value of bandwidths of the communication sending end in a predetermined time period. The target bandwidth frequency may be an uplink bandwidth frequency of the communication transmitting end, or a downlink bandwidth frequency of the communication transmitting end, and one of the uplink bandwidth frequency and the downlink bandwidth frequency is specifically selected for encryption during each communication. The predetermined bandwidth frequency can be a pre-agreed user-defined bandwidth frequency, and when the predetermined bandwidth frequency is greater than the average bandwidth frequency, the uplink bandwidth frequency and the communication content are encrypted together to obtain encrypted transmission data; and when the preset bandwidth frequency is smaller than the average bandwidth frequency, the downlink bandwidth frequency and the communication content are encrypted together to obtain encrypted transmission data. The judgment rule may be predetermined and only grasped by the communication transmitting end and the communication receiving end, optionally, the communication transmitting end may transmit the uplink bandwidth frequency, the downlink bandwidth frequency, and the average bandwidth frequency to the communication receiving end, and the communication receiving end determines whether the uplink bandwidth frequency adopted by the communication transmitting end is encrypted or the downlink bandwidth frequency is encrypted based on the grasped predetermined bandwidth frequency, and solves the secret key back according to the result. The method can further improve the cracking difficulty of attackers and ensure the safety of communication.
Fig. 3 is a schematic flowchart of a communication decryption method according to an embodiment of the present invention, as shown in fig. 3, the method includes the following steps:
step S302, receiving the target bandwidth frequency and the encrypted transmission data sent by the communication sending end.
In this step, the target bandwidth frequency may be a bandwidth frequency of the communication transmitting end, and a value that fluctuates at any time may be set with a three-party interface at the communication transmitting end, so as to receive the communication content of the communication transmitting end and monitor the target bandwidth frequency of the communication transmitting end.
And step S304, based on the target bandwidth frequency, decrypting the part corresponding to the target bandwidth frequency in the encrypted transmission data to obtain the communication key.
In this step, the communication receiving end may determine a portion corresponding to the target bandwidth frequency from the encrypted transmission data based on a composition format of the encrypted transmission data agreed with the communication transmitting end, that is, a ciphertext obtained by encrypting the target bandwidth frequency by the communication transmitting end, and then perform an inverse operation of the encryption based on the ciphertext and the received target bandwidth frequency to obtain the communication key.
Step S306, the encrypted transmission data is decrypted by using the communication key, and communication content is obtained. And decrypting the part corresponding to the communication content in the encrypted transmission data by using the communication key to obtain the communication content.
Through the steps, the purpose of encrypting by adopting different keys in each communication is achieved, so that the technical effects of improving the safety and reliability of communication encryption are achieved, and the technical problem that the communication is unsafe due to the fact that the keys are easy to leak in the communication process is solved.
As an alternative embodiment, in a case where the encrypted transmission data is further generated according to a predetermined encryption constant, decrypting a portion of the encrypted transmission data corresponding to the target bandwidth frequency based on the target bandwidth frequency to obtain the communication key includes: and based on the target bandwidth frequency and the encryption constant, decrypting the part, corresponding to the target bandwidth frequency and the encryption constant, in the encrypted transmission data to obtain the communication key.
In an alternative embodiment, the encryption constant may be a complex constant predetermined by the communication sender and the communication receiver, such as a universal constant, and the constant does not need to be transmitted through a channel. After receiving the encrypted transmission data and the target bandwidth frequency, the communication receiving end processes the encryption constant and the target bandwidth frequency based on the same operation as that of the communication transmitting end, for example, adds or multiplies the encryption constant and the target bandwidth frequency, then obtains a part corresponding to the operation result from the encrypted transmission data, and performs an inverse operation of encryption according to the operation result to obtain a communication key.
