Examples
As shown in fig. 1, the 3.5mm earphone plug is divided into a left channel L, a right channel R, a ground G and a microphone M according to different functions.
And opening different passages according to different depths of the earphone inserting/extracting monitoring equipment. This process of opening the path may form a cryptographic rule definition.
For example, for a three-segment earphone, 1/3 of the left channel L channel is inserted, 1/3 of the right channel R channel is inserted, and 1/3 of the left channel L channel is pulled out, so that a group of LRL codes is formed. For another example, a four-segment headset may form a set of passwords as LRMRMG.
Comparing the acquired password with the password reserved in the monitoring equipment, and safely unlocking the monitoring equipment if the acquired password is matched with the password reserved in the monitoring equipment.
As shown in fig. 2, the headset-end unlock password entry structure is described as follows:
the process of gradually inserting the earphone plug into the earphone hole:
when the left channel L circuit is turned on, a high level of a signal 1 position is generated, and the system marks the level as L1;
when the right channel R circuit is turned on, a high level of the signal 2 position is generated, and the system marks the level as R1;
when the ground GND circuit is turned on, a high level of the signal 3 position is generated, and the system marks the high level as G1;
when the microphone MIC circuit is on, a high level is generated at the signal 4 position, which the system notes as M1.
The process of gradually pulling out the earphone holes by the earphone plug:
when the left channel L circuit is disconnected, a low level of a signal 1 position is generated, and the system marks the level as L2;
when the right channel R circuit is disconnected, a low level of the position of a signal 2 is generated, and the system marks the level as R2;
when the ground GND circuit is disconnected, a low level of the signal 3 position is generated, and the system marks the level as G2;
when the microphone MIC circuit is disconnected, a low level is generated for the signal 4 position, which the system notes as M2.
If the earphone is inserted 1/4, an L1 signal is generated and recorded; when the signal is inserted into the 2/4 position, an R1 signal is generated and recorded; when the signal is inserted into the 3/4 position, a G1 signal is generated and recorded; when the position is pulled out to the 2/4 position, a G2 signal is generated and recorded; when the device is pulled out to the 1/4 position, an R2 signal is generated and recorded; when the earphone is pulled out completely, an L2 signal is generated and recorded. The whole process generates a set of signal values L1R1G 2R2L2, which can be regarded as a set of cryptographic sequences. More complex plug and play processes may form more complex cryptographic sequences, such as L1R1G 2R1G 2R2L2. If the earphone is designed with more than one circuit on hardware, a more unique signal bit can be generated, a unique cipher sequence can be generated, the earphone cannot be simulated, and the confidentiality degree is higher.
Password verification system:
comparing the input password acquired and formed by the earphone end with the preset password of the monitoring equipment, and unlocking the monitoring equipment when the input password meets the expected value; if the preset value is not met, the user is required to reenter. The use process is shown in fig. 3.
