Fig. 2 is a flow chart of a communication encryption method according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
step S202, a target bandwidth frequency of a communication transmitting end is obtained.
In this step, the target bandwidth frequency may be a value that fluctuates over time, rather than a fixed bandwidth frequency value. A three-way interface can be arranged at the communication transmitting end and used for receiving the communication content of the communication transmitting end and monitoring the target bandwidth frequency of the communication transmitting end.
Step S204, encrypting the target bandwidth frequency and the communication content to obtain encrypted transmission data.
In the step, the target bandwidth frequency and the communication content are encrypted by adopting the same encryption method, so that 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 the encrypted transmission data.
Step S206, the target bandwidth frequency and the encrypted transmission data are sent to the 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 can decrypt the encrypted transmission data after receiving the key, so as to obtain the communication content which the communication sending end wants to transmit. Optionally, the communication receiving end may determine the encrypted target bandwidth frequency from the encrypted transmission data according to a predetermined encrypted transmission data format, then perform an encrypted inverse operation based on the encrypted target bandwidth frequency, solve the key, and decrypt the encrypted transmission data after the communication receiving end takes the key, so as to obtain the communication content.
Through the steps, the aim of encrypting by adopting different keys in each communication is fulfilled, so that the technical effects of improving the safety and reliability of communication encryption are realized, 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 fluctuated, the secret keys used by the two communication parties for encrypting the communication content are different each time, the communication content is difficult to be obtained by the outside through a violent cracking method, and the communication safety is ensured.
As an alternative embodiment, encrypting the target bandwidth frequency and the communication content to obtain encrypted transmission data, a predetermined encryption constant may be obtained first; 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 agreed in advance by the communication transmitting side and the communication receiving side, and for example, a gravitational constant may be employed as the encryption constant. The communication transmitting end can firstly operate the encryption constant and the target bandwidth frequency, and then encrypt by adopting an encryption algorithm. In 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 acquire the key through inverse operation, but the communication content intercepted by the interceptor does not comprise the encryption constant, so that the key cannot be cracked. In this embodiment, the difficulty of cracking can be improved and the communication security can be improved by selecting a complex encryption constant.
As an alternative embodiment, the target bandwidth frequency and the communication content are encrypted, so as to obtain encrypted transmission data, which may be obtained by the following manner: respectively taking the modes of the target bandwidth frequency and the communication content to obtain a plurality of groups of mode values; the multiple sets of modulus values are converted into encrypted transmission data in a string format. Optionally, in the process of converting the multiple groups of modulus values into the encrypted transmission data in the character String format, multiple groups of modulus values can be multiplied by the target bandwidth frequency to be converted into a byte array, then the byte array is converted into a String character String, and the formed character String is used as an encryption result, namely the encrypted transmission data to be transmitted, so that the communication safety is further improved.
As an alternative embodiment, the method for obtaining the target bandwidth frequency of the communication sending end may include the following steps: acquiring a preset bandwidth frequency and an average bandwidth frequency of a communication transmitting end, wherein the target bandwidth frequency comprises the average bandwidth frequency; 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 transmitting 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, the first bandwidth frequency of the communication transmitting end is obtained, and the uplink bandwidth frequency of the communication transmitting end can be obtained when the predetermined bandwidth frequency is greater than the average bandwidth frequency; and acquiring the downlink bandwidth frequency of the communication transmitting end under the condition that the preset bandwidth frequency is smaller than the average bandwidth frequency.
In this optional embodiment, the average bandwidth frequency may be an average value of the current uplink bandwidth frequency and the downlink bandwidth frequency of the communication transmitting end, or may be an average value of bandwidths of the communication transmitting end in a predetermined period of time. 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 target bandwidth frequencies is specifically selected for encryption during each communication. The predetermined bandwidth frequency can be a preset self-defined bandwidth frequency, and when the predetermined bandwidth frequency is larger than the average bandwidth frequency, the uplink bandwidth frequency and the communication content are adopted to encrypt to obtain encrypted transmission data; and when the preset bandwidth frequency is smaller than the average bandwidth frequency, encrypting the downlink bandwidth frequency and the communication content together to obtain encrypted transmission data. The judgment rule may be agreed in advance, and only the communication transmitting end and the communication receiving end grasp the judgment rule, alternatively, 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 communication transmitting end adopts the uplink bandwidth frequency to encrypt or adopts the downlink bandwidth frequency to encrypt based on the grasped preset bandwidth frequency, and accordingly, the secret key is reversely solved. The method can further improve the cracking difficulty of an attacker and ensure the safety of communication.
Fig. 3 is a flow chart 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 the value that fluctuates at any time may set a three-way interface at the communication transmitting end, for receiving communication content of the communication transmitting end, and monitoring the target bandwidth frequency of the communication transmitting end.
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, from the encrypted transmission data, a portion corresponding to the target bandwidth frequency, that is, a ciphertext obtained by encrypting the target bandwidth frequency by the communication transmitting end, based on a composition format of the encrypted transmission data agreed with 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.
And step S306, decrypting the encrypted transmission data by using the communication key to obtain the communication content. 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 aim of encrypting by adopting different keys in each communication is fulfilled, so that the technical effects of improving the safety and reliability of communication encryption are realized, 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 also 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 decrypting the part corresponding to the target bandwidth frequency and the encryption constant in the encrypted transmission data based on the target bandwidth frequency and the encryption constant to obtain the communication key.
In an alternative embodiment, the encryption constant may be a complex constant agreed in advance by the transmitting end and the receiving end of the communication, such as a gravitational constant, which 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 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 carries out encrypted inverse operation according to the operation result to obtain the communication key.

Step 1, obtaining a plaintext to be encrypted, namely communication content, and encrypting the plaintext to be encrypted and bandwidth frequency obtained by monitoring in real time by taking a UUID of a first character of the plaintext plus a communication transmitting end as a unique identifier to obtain encrypted transmission data.
And 2, obtaining the uplink, downlink and average bandwidth frequencies of the bandwidth of the communication transmitting end, and carrying out different encryption algorithms by matching through different bandwidth transmission frequencies.
And 2.1, when the preset bandwidth frequency is smaller than the current average bandwidth frequency, the communication transmitting end performs modular operation on the universal gravitation constant, the downlink bandwidth frequency, the average bandwidth frequency, the current bandwidth frequency and the plaintext respectively.
And 2.2, when the preset bandwidth frequency is larger than the current average bandwidth frequency, the communication transmitting end performs modular operation on the universal gravitation constant, the uplink bandwidth frequency, the average bandwidth frequency, the current bandwidth frequency and the plaintext respectively.
And step 3, multiplying the obtained modulus value with the corresponding bandwidth frequency to convert the modulus value into a byte array, and converting the byte array into String to form a new character String which is the encrypted transmission data.
