step S201: responding to an offline password request sent by a terminal, and determining whether the terminal is in a normal offline state; if yes, executing step S202, otherwise, executing step S203;

It should be noted that the type of the input information of the password generation algorithm of the terminal is identical to the input information of the password generation algorithm of the management terminal.
There may be two ways to generate or update the random key variable.
The first method comprises the following steps: and in the networking state, updating the random key variable according to a preset first period, and sending the updated random key variable to the terminal through communication connection between the terminal and the networking state, so that the terminal generates a second offline password according to the updated random key variable.

The two modes can exist simultaneously or alternatively.
Step S203: and refusing to provide the first offline password for the terminal, and determining that the terminal is abnormally offline.
The first offline password is managed, so that the offline use of the terminal is more standard, and meanwhile, the state of the terminal, such as offline or networking, can be managed through the management of the first offline password. For example, after the first offline password is provided, the terminal state may be marked as offline, and after the terminal networking information is subsequently received, the terminal state is modified into the networking state.

The following takes the example of implementing PDA offline use by interaction between a PDA and a terminal for single-scan codes in the field of logistics and managing PDA offline by a terminal (for example, a PC terminal) as an example, to describe specific steps of PDA offline use and PDA management, as shown in fig. 7, the interaction process may include the following steps:
step S701: negotiating a generation rule of an offline password between the PDA and the PC end through a secure channel;
for example, the offline password generation rule is as follows: and generating an intermediate key according to the current date, the ID of the site where the PDA is located and the random key variable, and intercepting a plurality of bits of the intermediate key to be used as an off-line password. Wherein, the current date can be obtained by consulting the digital calendar of the respective end device, and the site ID can be obtained by consulting the record of the respective database. Illustratively, the rule for generating the offline password includes: and intercepting a plurality of bits of the result through (the year, month and day splicing site ID) key variables to obtain the offline password. Further, there are the following examples:
"year, month, day" is 20210902, the venue ID is 123456, the key variable is 31, and the result is: 20210902123456 × 31 ═ 626537965827136. The fourth to ninth bits are truncated to obtain the offline password 537965. Through the generation rule of the offline password, the PDA terminal can be prevented from cracking the offline password, so that the security of the offline password is ensured, and the offline state of the PDA can be more normatively controlled.
Step S702: after determining that the PDA is in a networking state, the PC terminal generates and updates random key variables at regular time and sends the updated random key variables to the PDA;
that is, the PC terminal generates and updates the random key variable regularly after determining that the PDA is in the networking state, and the PC terminal does not update the random key variable in the normal off-line state of the PDA. Through the process, the random key variable of the normal off-line PDA is still consistent with the random key variable of the PC terminal, but the abnormal off-line PDA cannot be synchronized to the PC terminal, so that the PDA is further monitored. I.e., an abnormally offline PDA cannot obtain offline usage rights in subsequent offline applications.
In this step, the determination that the PDA is in a networked state may be that the last received PDA state was in a networked state or that an offline request from the PDA was not received. It is also possible that the PC side and the PDA negotiate together to set the PDA to interact with the PC side in a networked manner at a specific time. For example, the interaction may be set every 10 minutes, or may be carried forward at 15:30 per day, or when the PC side and PDA are networked for other operations. When the PC side and the PDA are interacted, the PC side can generate and update the random key variable.
When the PDA network interacts with the PC end, the PC end generates a random key variable through a random function or a manual mode, and sends the random key variable to the PDA, and the PDA receives the random key variable. The type of random key variable may be an integer, a letter, etc. When the random key variable is a non-integer type, it needs to be converted into an integer type for the subsequent generation of the offline password, for example, when the random key variable is AB, it can be converted into an integer 6566 by ASCII code. The length of the random key variable is not limited, and the random key variable can meet the application requirement, for example, the random key variable can be set to be an integer 65, and the length is 2 bits; it can also be set to an integer 11234, 5 bits in length. Even if the illegal user knows the operation steps for generating the offline password, the illegal user still cannot obtain the offline password because the key variable with strong randomness cannot be obtained, and the confidentiality can be effectively improved due to the existence of the key variable.
Step S703: in the interaction process of the PDA and the PC, the PC generates a first offline password according to the generation rule of the offline password and the random key variable and stores the first offline password in a database or file information of the PC;
step S704: after receiving the random key variable, the PDA generates a second offline password according to the negotiated offline password generation rule and the negotiated random key variable, and stores the offline password in a database or file information of the PDA;
step S705: when a user applies for offline state, the PDA can input an offline password in the form of a pop-up interface and the like, and at the moment, the user can contact an administrator at the PC end in a manual or other non-networking way;
step S706: after the PC terminal determines that the PDA is in a normal off-line state, a first off-line password is provided for a user of the PDA;
in this step, the PC terminal refers to the site ID of the site where the PDA applying for offline is located, and then refers to the networking states of other mobile terminals in the site where the PDA is located according to the site ID to determine whether the offline state of the PDA is normal. For example, in other PDAs in a place where the PDA requesting for offline is found, if more than half of the other PDAs are found to be offline, it is determined that the offline state of the PDA is normal, otherwise, it is determined that the offline state is not reasonable.
Step S707: the PDA receives a first offline password input by a user and matches the first offline password with a stored second offline password;
step S708: if the matching result indicates that the first offline password is the same as the second offline password, the PDA is allowed to operate offline, and the current process is ended;
step S709: and if the matching result indicates that the first offline password is different from the second offline password, the PDA is prohibited from offline operation.
When the PDA is in an off-line state normally, the administrator provides the first off-line password recorded by the PC terminal to the PDA user in a manual mode such as short message or telephone, and the user inputs and confirms the first off-line password to the password input interface of the PDA. After the confirmation, the PDA judges whether the first off-line password input by the user is the same as the mobile password recorded by the PDA through a character string matching function, if so, the PDA is allowed to perform off-line operation, otherwise, the user is refused to log in and use the PDA.
In an exemplary scenario, when a logistics shipper sends a good, the two-dimensional code on the good needs to be scanned through a PDA login platform, after the scanning is successful, the PDA generates a record of successful shipment, and an appraiser can perform performance appraisal on the shipper through the record of successful shipment of the PDA. Under the normal condition, the process of logging in the PDA to scan and deliver goods is carried out under the condition of networking, so that the PC end can directly judge whether the goods are reasonably delivered in a networking mode, and if the goods are unreasonable, for example, an order needing to be delivered is cancelled, the PC end can judge that the goods are unreasonable to be delivered through the existing data records, and the goods are rejected. The logistics personnel can also scan without a network, and when the logistics personnel logs in for scanning, the logistics personnel needs to input an offline password. At the moment, logistics personnel can contact an administrator of the use management terminal through non-networking modes such as telephone, short message and the like to acquire the offline password. After the logistics personnel input the offline password, the handheld mobile terminal judges whether the input offline password is correct, if so, the logistics personnel is allowed to scan for delivery, and if not, the logistics personnel is rejected.
It should be noted that the PDA may be other terminal equipment for logistics, such as a mobile terminal installed with logistics management software.
