The Random Password Server (RPSID) generates a random password based on a series of seeds, and the password is updated at certain time intervals; or generating the password by a reporting key device (DCRKD) connected with a Random Password Server (RPSID), and carrying out the password synchronization with the random password server and the random key reporting message database at regular time. Specifically, as shown in fig. 2 and fig. 3, reporting of the random key reporting message Database (DRKRM) is triggered once at each time of synchronization, that is, the reporting key device (DCRKD) sends the encrypted information containing the password from the random key reporting message Database (DRKRM) to the Remote Key Management Data Center (RKMDC). And the key reporting device (DCRKD) directly connected with the intelligent device is always connected with the intelligent device through a direct connection interface to synchronize the password with a Random Password Server (RPSID). After each synchronization, the key reporting device DCRKD fills the latest password into the random key reporting message Database (DRKRM), encrypts the latest password based on the ID and the key of the device, and then submits the encrypted message to a Remote Key Management Data Center (RKMDC), thereby implementing the overall password synchronization of the system.
Further, in the present invention, a Random Key Report Message database (Device Random Key Report Message DRKRM) is used to perform predetermined formatting on a single Random Key Report Message or multiple Message groups; the predetermined format may be a message format between a Random Password Server (RPSID) on the smart device and a reporting key device (DCRKD), or a message format between a reporting key device (DCRKD) and a Remote Key Management Data Center (RKMDC).
Further, in the present invention, a Key Reporting Device (Direct Connection Reporting Key Device, DCRKD for short) directly connected to the intelligent Device provides the intelligent Device with receiving and forwarding of messages, so as to ensure the reliability and security of the system itself. The preferable reporting key device (DCRKD) is a single chip microcomputer system, and the safety and the reliability of the system are ensured to the maximum extent. Under the security environment, the key is signed, namely, the ID and the key are built in, and the ID and the key are simultaneously stored on a MAIN/decoder belonging to a Remote Key Management Data Center (RKMDC) for ensuring the communication between a reporting key device (DCRKD) and the MAIN/decoder to be secure and reliable.
The key reporting device (DCRKD) directly connected with the intelligent device is always in butt joint with the intelligent device through a direct connection interface to synchronize the password with a Random Password Server (RPSID) on the intelligent device. After each synchronization, the DCRKD fills the latest password into a random key report message Database (DRKRM), encrypts the password based on the ID and the key of the DCRKD, and then submits the encrypted message to a Remote Key Management Data Center (RKMDC).
Further, in the present invention, a Remote Key Management Data Center (Remote Key Management Data Center, RKMDC for short) at least includes a MAIN/decoder, a Data/Data server, and a SHOW/operation interface, where the MAIN/decoder receives and decrypts an encrypted message reported by a reporting Key device (DCRKD), and then forwards the encrypted message to the Data/Data server, and the Data/Data server enables a centralized Key manager to access and know a random password of a specific device based on the SHOW/operation interface, and notify field personnel to operate the device.
The working principle of the password centralized management system of the invention is as follows:
firstly, after the operating system on the intelligent device is started, a random password server (RPSID for short) with super user authority is executed, and the RPSID is set to replace the random password in the system at intervals.
The random cipher may be part of a cipher generation seed by summing the total number of messages sent and received locally and the content of the message, including but not limited to. The random password may be a password of an admin user of windows, a password of a root user of linux, or an admin user password specified by a web interface of a router, and of course, may also be a boot password of Android and iOS, even a login password of specific software (such as a pay pal, a WeChat, a bank APP, and the like) in a system, and may also be a password of some action (such as a transfer/confirmation password). When a large amount of scattered intelligent equipment (or programs/execution actions on the intelligent equipment) are managed, random password centralized management mode is selected to access any intelligent equipment, and the method is safe and simple.
Secondly, whether the password of the intelligent device is changed or not, a Random Password Server (RPSID) sends the current random password to a reporting key device (DCRKD) regularly based on a direct connection interface; the reported key device (DCRKD) can also calculate the password and inform the Random Password Server (RPSID) to execute replacement. And executing a Random Password Server (RPSID) with super user authority, and replacing the random password in the system by the Random Password Server (RPSID) according to the setting at intervals.
And the direct connection interface may be: the method comprises the following steps of pin direct connection, double-port RAM reading and writing, optical coupler/relay/MOS on-off indication, a USB interface, a TTL/232/485 serial port, an industrial field bus, an optical fiber, a network cable, point-to-point wireless, a virtual link established by 3G/4G/5G, WIFI, a satellite link and the like, wherein the method comprises but is not limited to the mode.
The reporting key device (DCRKD) is independently composed of a single chip microcomputer, ID and a key of the reporting key device can be used for ID number allocation and key allocation in a security (or secret-related) machine room, and a uniform key is not used, so that the problem that the reporting key device is cracked by a network packet or violently cracked is solved.
And thirdly, the random password server, the reported key device and the intelligent device in the system are encrypted based on the message format transmitted by the direct connection interface, namely after the random key reported message Database (DRKRM) and the reported key device (DCRKD) directly connected with the intelligent device are synchronized, and are sent to a Remote Key Management Data Center (RKMDC), and the system is positioned in a security network, has quick transmission speed and does not have external interference.

The centralized password administrator may access the DATA/DATA service, also located within the secure intranet, based on the SHOW/interface, and obtain therefrom the random password for the particular system (application/action), and then inform the field personnel and complete the operation therewith.
Finally, field personnel, if required to log into the system (or enter a particular application, perform a particular action), need to contact a centralized password administrator located in the secure room, have access to a Remote Key Management Data Center (RKMDC) located in the secure room by the centralized password administrator,
the reporting key device (DCRKD) is generally realized by adopting a single chip microcomputer, does not use any operating system, can be considered to be incapable of being attacked by a network, is internally provided with an ID and a data encryption key under a secure environment, and the ID and the data encryption key are also recorded in the MAIN/decoder, so that the communication between the reporting key device (DCRKD) and the MAIN/decoder can be ensured to be secure and reliable.
