Setup module 103, the system for embedded device described in the password update using the system account obtained
The password of account.
Referring to Fig. 4, Fig. 4 is the Program modual graph of 10 second embodiment of login password protective program proposed by the present invention.
On the basis of first embodiment, login password protective program 10 further includes update module 104.
Update module 104 sends a password update request to server for timing (for example, at interval of 2 hours),
And the password that server responds the new system account that password update request returns is received, the password of new system account is set
Password login system account in the system account for setting preset kind operating system, for user based on new system account.
Therefore the password that the present embodiment timing updates system account can further improve security of system.
Referring to Fig. 5, Fig. 5 is the flow chart of login password guard method first embodiment proposed by the present invention.
In the present embodiment, which comprises
S10, after starting in embedded device and running preset kind operating system, preset kind is established with server and is communicated
Connection.For example, preset kind communication connection can be the long connection based on TLS.
When communicating to connect failure, embedded device is established with server again at interval of preset duration (for example, 30 seconds)
Preset kind communication connection.
S20, embedded device are communicated to connect based on the preset kind of foundation, and the system account generated at random is obtained from server
The password at family.
The password of the system account is ROOT password, it is the character string generated at random by server, server
The password of different system accounts can be generated at random for different embedded devices.
The mode of the password for the system account that embedded device generates at random from server acquisition includes following scheme:
Scheme one:
Server generates the password of system account at random and is stored in default memory space (for example, memory of server)
In, embedded device is searched from the default memory space of server and obtains the password of system account.
Scheme two:
Embedded device sends a password request to server and it is close to respond this after server receives the password request
Code request, the random password for generating system account corresponding with the password request.
Scheme three:
Embedded device sends a password request to server, and server is successfully established in preset kind communication connection
Afterwards, the password of system account is generated at random and by the password storage of the system account generated at random in default memory space, and
After receiving the password request, using the password of the system account generated at random as the corresponding system account of the password request
Password.
Scheme four:
Preset kind communication connection based on foundation, the code key generated at random is obtained from server, it is corresponding to calculate code key
The password of system account.Code key is the character string generated at random by server.
Embedded device further includes encryption unit (for example, encryption lock), after getting code key, needs to drive encryption single
Member calculates the password to the corresponding system account of code key.
S30, using acquisition system account password update embedded device system account password.
Referring to Fig. 6, Fig. 6 is the flow chart of login password guard method second embodiment proposed by the present invention.
On the basis of first embodiment, the method also includes:
S40, embedded device timing (for example, at interval of 2 hours) send a password update request to server, and
Receive the password that server responds the new system account that password update request returns.
The password of new system account is arranged into the system account of preset kind operating system for S50, embedded device,
Password login system account for user based on new system account.
The present embodiment timing updates the password of system account, improves the safety of system.
Further, the present invention also proposes that a kind of computer readable storage medium, the computer readable storage medium are deposited
Contain login password protective program, the login password protective program can be executed by least one processor so that it is described at least
One processor executes the login password guard method in any embodiment.
