And 1032, performing first displacement operation on the first segment data by using the amplitude value of the ultrasonic wave to obtain third segment data.

Step 2024, performing a reverse second displacement operation on the third segmented data by using the ultrasonic frequency value to obtain second segmented data.
Optionally, the reverse second shift operation is a right shift or left shift operation. Specifically, the second shift operation in step 1033 is reversed. If the second displacement operation is a left displacement operation, the reverse second displacement operation is a right displacement operation; if the second displacement operation is a right displacement operation, the reverse second displacement operation is a left displacement operation.

Specifically, the first electronic device and the second electronic device are successfully paired through ultrasonic waves. Here, the first electronic device and the second electronic device successfully pair with each other by the ultrasonic wave means that both the first electronic device and the second electronic device record ultrasonic information of the other party, respectively, and confirm that each other has received the ultrasonic information of the other party.
As an optional implementation manner, the method in the embodiment of the present application may further include:
i, receiving second ultrasonic information of the first electronic equipment;
here, the second electronic device can verify whether the object communicated with the second electronic device is the first electronic device by using the second ultrasonic information, so that the subsequent second electronic device can be prevented from decrypting irrelevant encrypted text, and unnecessary power consumption can be further avoided.
ii, if the second ultrasonic information is successfully detected, step 202 is executed, that is, the encrypted text is reversely shifted and decrypted by using the ultrasonic amplitude value and the ultrasonic frequency value, so as to obtain the first data.
The successful detection of the second ultrasonic information means that the second ultrasonic information is successfully matched with the previously recorded ultrasonic information transmitted by the first electronic device.
Since the first electronic device side encrypts the first text by using the first ultrasonic information (i.e., the ultrasonic information sent by the second electronic device), the first text can be obtained by decrypting the encrypted text by using the first ultrasonic information.
The information decryption method in the embodiment of the application can also be used for receiving the encrypted text and the second ultrasonic information which are respectively sent by the first electronic equipment under the condition that the first electronic equipment and the second electronic equipment are successfully paired through ultrasonic waves, so that the received encrypted text can prevent privacy information in the text from being stolen and peeped and leaked, and the purpose of protecting the privacy of a user is achieved; and finally, under the condition that the second ultrasonic information is successfully detected, the encrypted text is decrypted according to the first ultrasonic information to obtain the first text, so that the purpose of decrypting the encrypted text sent by the first electronic equipment communicating with the second electronic equipment is achieved.

In this way, when both the first electronic device and the second electronic device respectively record the ultrasonic information of the other party and confirm that the ultrasonic information of the other party has been received, it is determined that the first electronic device and the second electronic device are successfully paired by the ultrasonic wave.

The information interaction process between the first electronic device and the second electronic device after the pairing by the ultrasonic wave is successful is explained by the following example two.
Example two
In this example two, the first electronic device is device a and the second electronic device is device B. And device a acts as the sender of the information and device B acts as the receiver of the information. Referring to fig. 4, the specific interaction process is as follows:
s401, the device A obtains a text m through editing by an input method.
S402, the device A encrypts the text m by using the ultrasonic information 2 to obtain an encrypted text m'.
Specifically, the apparatus a can encrypt the text m by shifting it left or right using the ultrasonic amplitude value and frequency value in the ultrasonic information 2.
The encryption algorithm can be designed as follows:
carrying out front and back halving segmentation on binary ASCII codes of each bit letter or number, carrying out left shift on the front-stage binary ASCII, carrying out right shift on the rear-stage binary ASCII codes by ultrasonic frequency values, and then converting the binary ASCII codes subjected to the displacement operation into 16 systems to be used as encrypted ciphertext texts so as to achieve the purpose of encryption.
S403, the device a transmits the encrypted text m' to the device B, and transmits the ultrasonic information 1.
S404, the device B receives the encrypted text m 'and the ultrasonic information 1, and displays the encrypted text m' on the screen of the device B.
S405, the device B matches the ultrasonic information 1 sent by the device A and recorded locally before with the currently received ultrasonic information 1, and a matching result is obtained.
And S406, if the matching result shows that the matching is successful, the device B decrypts the encrypted text m' by using the ultrasonic information 2 to obtain the text m and displays the text m on the screen of the device B.
