The invention relates to the field of security protection of intelligent door locks, in particular to an encryption, decryption and authentication method for an intelligent door lock in an offline environment.
Background
At present, various intelligent door locks with internet access functions appear in the rapid development of unmanned hotels, and the intelligent door locks can be unlocked remotely only by a user through mobile phone application software or a PC (personal computer) terminal. In the prior art, most of intelligent door locks implement identity authentication in the following ways: the password generated remotely by the server is sent to the intelligent door lock through the network on one hand, and on the other hand, the password is simultaneously sent to the mobile phone or the PC end of the user. The intelligent door lock can realize the unlocking operation through identifying the password and passing the authentication. However, in the actual use process, the situation that the intelligent door lock is not connected to the network easily occurs, and once the intelligent device is not connected to the network, the authentication needs to be carried out through the offline password. The existing offline password is usually preset in the intelligent door lock device, and can be authenticated through the preset offline password when the device is not connected to a network, but the offline password can be used all the time in the validity period, so that the password is easily leaked when the device is used for a long time after being disconnected from the network, and the personal and property safety of a user is endangered. Particularly, when the password lock is applied to an unmanned hotel, a user can replace the password during a network break period without losing the password, and the user who has returned can open the door through the password, so that the password lock is extremely unsafe.

when the intelligent door lock cannot be connected with the system server, namely the intelligent door lock is in an off-line state, firstly, the system server generates a password by using the encryption method and sends the password to a client or other users; then, the customer or the user inputs the password into the intelligent door lock, the intelligent door lock receives the password and decrypts the password by using the decryption method, and then the decrypted information is used for authentication through the authentication method, so that the intelligent door lock can also be unlocked through the password in an off-line state; wherein,
the encryption method comprises the following steps: and mixing the intelligent door lock information, the password aging information and the password authority information, then packaging the data, and carrying out algorithm encryption on the packaged data by combining a key to generate a password.
The decryption method comprises the following steps: after receiving the password, the intelligent door lock decrypts the password through the key, performs data unpacking and data separation on the password, and separates out intelligent door lock information, password aging information and password authority information.
The authentication method of the intelligent door lock comprises the following steps: the intelligent door lock firstly checks the intelligent door lock information, then checks the password aging information after the intelligent door lock information passes the password aging information, identifies the password authority information after the password authority information passes the password aging information, and if the authority of the password is higher than the authority of the password input last time, the authentication is passed and the password with low authority is forbidden.
Preferably, the password aging time information is used for setting the usage aging of the password.
Preferably, the intelligent door lock information is used for setting the intelligent door lock corresponding to the password.
Preferably, the password authority information is used for setting the authority of the password, and a plurality of passwords generated by the system server have different or the same authority.
Preferably, after the intelligent door lock firstly passes the verification of the intelligent door lock information and the verification of the password aging information, the password authority information is identified, and when the password with the same authority is input, the intelligent door lock passes the authentication; when the password with lower authority is input, the authentication of the intelligent door lock is not passed.
Compared with the prior art, the invention has the beneficial effects that:
in addition, by setting the authority of the offline password, after the intelligent door lock information and the password aging information are checked, the offline password with low authority can be forbidden to operate through the offline password with higher authority, the management of the offline password is enhanced, the condition that the offline password of a returned user is continuously used in an effective period is avoided, and the safety of the intelligent door lock is greatly improved.

Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.
An encryption, decryption and authentication method for an intelligent door lock in an offline environment is used for generating a password (offline password) used by the intelligent door lock in a hotel system in the offline environment, and a randomly generated key and corresponding intelligent door lock information are synchronized into a system server when the intelligent door lock is connected with the system server last time.
As shown in fig. 1, the encryption method specifically includes: and mixing the intelligent door lock information, the password aging information and the password authority information, then packaging the data, and carrying out algorithm encryption on the packaged data by combining a key to generate an offline password (the offline password is generated only when a user requests the offline password every time). The password time information is used for setting the use time of the offline password, the intelligent door lock information is used for setting the intelligent door lock corresponding to the offline password, the password authority information is used for setting the authority of the offline password, and the generated offline passwords have different or same authority.
As shown in fig. 2, the decryption method specifically includes: after the intelligent door lock receives the password, the off-line password is decrypted through the key, data unpacking and data separation are carried out on the off-line password, and intelligent door lock information, password aging information and password authority information are separated.
As shown in fig. 3, the authentication method of the intelligent door lock includes the following specific steps:
firstly, the intelligent door lock checks the intelligent door lock information, if the intelligent door lock information of the offline password is not matched with the intelligent door lock, the authentication fails, and if the intelligent door lock information of the offline password is matched with the intelligent door lock, the second step is carried out;
secondly, checking the password aging information, if the password aging does not exceed the service life, the authentication fails, and if the password aging does not exceed the service life, the third step is carried out;
thirdly, identifying password authority information, when an offline password with higher authority is input, the intelligent door lock passes authentication, and the offline password with lower authority is forbidden; when the offline password with the same authority is input, the intelligent door lock passes authentication; when the offline password with lower authority is input, the authentication of the intelligent door lock is failed, and the authentication is failed.
Example 1
And when the intelligent door lock is connected with the hotel server last time, the randomly generated key and the corresponding intelligent door lock information are synchronized into the system server.
When the intelligent door lock is in an offline state, the hotel system cannot be connected to the intelligent door lock, at the moment, a first user reserves a room corresponding to the intelligent door lock, and the hotel server sends a first offline password of the intelligent door lock to the first user. The first offline password received by the first user comprises time efficiency information, intelligent door lock information and authority information, and can only be used for authentication of the intelligent door lock in a time efficiency period.
After the first user returns from the hotel server, the hotel server allocates the room to the second user and sends a second offline password with higher authority of the intelligent door lock to the second user. And after the second user uses the second password to pass the authentication of the intelligent door lock, the first offline password is forbidden.
Example 2
After the first user transacts the check-out at the hotel server, the hotel server informs the cleaning staff to clean the room and sends a third offline password with the same authority of the intelligent door lock to the cleaning staff. After the cleaner is cleaned, the hotel server assigns the room to a second user and a second offline password with higher authority for the intelligent door lock. At this time, the first offline password and the third offline password are both low-authority and are disabled at the same time.
