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

The invention provides a reservation authorization method, which is applied to an authorization party. The method comprises the steps of generating a password field based on reservation time period parameters and an agreed key factor, the reservation time period parameters comprising effective time of reservation; generating an appointment authorization code comprising the password field and a time field corresponding to the appointment time period parameters; and sending the reservation authorization code to an authorized party, so that the authorized party provides the reservation authorization code for an intelligent lock for verification. The invention further provides an appointment authorization verification method applied to the intelligent lock, and a corresponding appointment authorization method and the intelligent lock. By means of the scheme, the unlocking requirement of a visitor when real-time remote unlocking is inconvenient can be met, and meanwhile, safety can be guaranteed.

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, ...
