example 1

[0064] Example 1: 8 5 88 8 28 7 Indicates that this is a reusable temporary password valid within 6 hours, and the valid time of the password is Tuesday or Friday, because:

[0065] R=5

[0066] D'=8

[0067] E'=7

[0068] D=D'-R>0? D'-R: 10+D'-R=8-5=3, so the effective duration is 6 hours

[0069] E=E'-R>0? E'-R: 10+E'-R=7-5=2=0010

[0070] The first three digits E[3..1] of the extension field E are coded as 001, so the effective date is Tuesday or Friday

[0071] The fourth bit E[0] of the extension field E is coded as 0, so the password field S is a reusable password.

example 2

[0072] Example 2: 2 3 10 3 twenty one 2 Indicates that this is a one-time password valid within 30 minutes, and the valid time of the password is on Sunday. because:

[0073] R=3

[0074] D'=3

[0075] E'=2

[0076] D=D'-R>0? D'-R: 10+D'-R=3-3=0, so the effective duration is 30 minutes

[0077] E=E'-R>0? E'-R: 10+E'-R=10+2-3=9=0b1001

[0078] The first three digits E[3..1] of the extension field E are coded as 100, so the effective date is Sunday

[0079] The fourth bit E[0] of the extension field E is coded as 1, so the password field S is a one-time password.

[0080] figure 2 It is an exemplary flow chart of a reservation authorization verification method in an embodiment of the present invention, and the verification method in this embodiment is applied to a smart lock.

[0081] Such as figure 2 As shown, the reservation authorization verification method in this embodiment includes:

[0082] S201. When receiving the input reservation authorization code to b...

example 3

[0138]Example 3: This example is slightly adjusted based on Example 2 for comparison. Assume that the effective time set when generating the password field is 2019-05-25 10:30, and the validity period is still 30 minutes, which is a one-time password. Since the date is Saturday, then E=0111=7, D=0.

[0139] When the smart lock receives the reservation authorization code to be verified entered by the user, the system time is 2019-05-25 11:11, then add 5 minutes to get T 1 =2019-05-25 11:16.

[0140] Then analyze D=0, that is, a 30-minute look-back period, then

[0141] N max =30 / 15=2

[0142] Then the smart lock performs HOTP verification calculations at the following three time points according to E=7, D=0,

[0143] When N=0, T=2019-05-25 11:07-15*0=2019-05-25 11:16

[0144] When N=1, T=2019-05-25 11:07-15*1=2019-05-25 11:01

[0145] When N=2, T=2019-05-25 11:07-15*2=2019-05-25 10:46

[0146] Since until N=N max When , the variables involved in the HOTP operation at th...

Abstract

This disclosure proposes a reservation authorization method, which is applied to the authorizing party. The method includes: generating a password field based on the reservation period parameter and the agreed key factor, and the reservation period parameter includes the effective time of the reservation; generating a password field including the password field and the reservation authorization code in the time field corresponding to the reservation period parameter; sending the reservation authorization code to the authorized party, so that the authorized party provides the reservation authorization code to the smart lock for verification. The present disclosure also proposes a reservation authorization verification method applied to a smart lock, as well as a corresponding reservation authorization method and a smart lock. Through the solution of the present disclosure, it is possible to realize the unlocking requirements of visitors when it is inconvenient to perform real-time remote unlocking, and at the same time ensure safety.

Description

technical field [0001] The present disclosure relates to the field of smart locks, and more specifically, to a reservation authorization method, reservation authorization verification method and device. Background technique [0002] At present, smart locks can realize real-time remote unlocking. The unlocking process is based on an asymmetric algorithm, which can ensure that the unlocking process is safe and controllable. [0003] However, for some scenarios, such as the homeowner’s friends or relatives urgently need to come to the house to pick up something at a certain time in the afternoon, but the homeowner may be on the plane or hosting a meeting at this time in the afternoon, in this case, real-time remote unlocking is the best Unable to solve the problem. Contents of the invention [0004] Aiming at the problems in the background technology, the present invention proposes a reservation authorization method, reservation authorization verification method and device, ...
