where h is the selected current timestamp, P is the senior administrator password, n is the number of temporary password bits, 0x55 ═ 85, 0xA ═ 170, and 0xA5 ═ 165.
For example, when the senior manager password and the temporary password are six digits, the time is 14 o' clock 22 min 30 s in 2019, 08 and 30 months, h is 19, the unit of the selected timestamp is year, and the temporary password for one hour in the future needs to be acquired,
and the calculation process of the first digit of the temporary password is as follows: [ (19+ p) ^0x55] × 6 ═ the first bit number of the temporary cipher;
the unit of the selected time stamp is month, h is 08, and the calculation process is [ (08+ p) ^0x55] × 6 ═ the second digit of the temporary password;
the unit of the selected timestamp is day, h is 30, and the calculation process is [ (30+ p) ^0x55] × 6 ═ the third digit of the temporary password;
the fourth digit of the temporary password is the fourth digit of the temporary password, the unit of the selected timestamp is time, h is 14, and the calculation process is that [ (14+ p) ^0x55] × 6 is the fourth digit of the temporary password;
the unit of the selected time stamp of the fifth digit of the temporary password is divided, h is 22, and the calculation process is that [ (22+ p) ^0x55] × 6 is the fifth digit of the temporary password;
and the sixth digit of the temporary password, the unit of the selected time stamp is divided, h is 30, the calculation process is [ (30+ p) ^0x55] × 6 ═ the sixth digit of the temporary password,
after the calculation is finished, the temporary password of one hour in the future can be obtained, and meanwhile, when the temporary password of one hour in the future is calculated, the singlechip also calculates the temporary password of one hour before the current timestamp, namely: [ ((h-1) + p) ^0x55] x n, the calculation process is the same as the temporary password for one hour in the future as described above;
after the calculation of the temporary password of two sets of different time stamps is accomplished, the singlechip opportunity compares the temporary password of these two sets of different time stamps, uses current time stamp as the critical point simultaneously, makes the time of this intelligent lock of singlechip control and the time of installing the mobile terminal of this intelligent lock APP carry out the synchronization, and the error rate that makes the temporary password appear in the time quantum on time limit range boundary is lower.
Wherein, the communication module is part or all of the following: bluetooth chip, zigbee chip and WIFI chip.
Further, the advanced administrator password is a digital password which is set by a user on the mobile terminal provided with the intelligent door lock APP.
Further, the temporary password is a numeric password and has the same number of bits as the advanced administrator password.
Further, the calculation process of the temporary password of the cloud server is the same as that of the singlechip, but the temporary password before the current timestamp is not calculated.
The gateway of the invention carries out calculation encryption setting on all digits of the temporary password, so that the temporary password can have different changes in different time periods, the temporary password is not easy to decrypt, the password protection coefficient is higher, meanwhile, when calculating the future temporary password of the current timestamp, the temporary password before the current timestamp is also calculated and compared, so that the error rate of the temporary password in the time period of the time boundary range boundary is lower, and the temporary password can exist only by using the advanced administrator password provided by a specific user, thereby ensuring the environmental security of a residence.
