Further, the financial security metering device further comprises:
and the safe AT processing module is used for receiving the usage information and controlling a preset authentication interface to authenticate the usage information through the safe middleware.
Further, the financial security metering device further comprises:
and the display screen is used for displaying data and at least displaying the usage information and the balance of the user wallet.
Here, the technical solution of the embodiment of the present application is specifically described with reference to a security metering cloud platform:
the financial security metering device comprises a central memory, a valve controller, a metering sensor, a financial security communication module and a display screen, wherein the financial security communication module is a financial security communication module and comprises a security middleware, a wallet module and a security AT processing module;
the security middleware is used for authentication and related business processing of the financial wallet;
the financial wallet module is mainly used for storing business keys in the metering industry and providing algorithm capacity required by the keys, and storing wallet ID, account information, users and other information for the financial wallet;
the safe AT processing module is used for processing safe AT instructions related to the safety function of the communication module, and specifically comprises the following steps: when a safe AT instruction is received, calling an authentication interface of a safety module through a safety middleware to perform operation authentication, and performing corresponding function processing after the authentication is passed;
when the metering operation is related, the financial security metering device accesses the financial security communication module through the security middleware to acquire the balance of the user wallet, and returns to the normal state if the balance exists; the central controller controls the valve to be opened, records the usage through the metering sensor and writes the usage data into the financial security communication module, and the usage is called circularly.
Further, the financial security communication module stores the real-time usage information, the daily usage information and the accumulated usage information, and reports the usage information and the balance information of the synchronous wallet at regular time according to the security metering cloud platform strategy.
Further, when the balance of the user wallet is insufficient, the financial wallet meter can be subjected to hardware wallet recharging through terminal equipment such as NFC/Bluetooth/infrared equipment.
In addition, the security metering cloud platform is used for issuing security service keys of the financial security metering device and managing the financial security metering device and a wallet account;
the issuing of the security service key of the financial security metering device is mainly based on a customized issuing strategy and combined with the personalized requirements of terminal security management to provide personalized issuing data for the financial security module for the first issuing;
meanwhile, a management interface for the issuing key, the issuing batch and the issuing node is provided.
The business key issuance is based on a hybrid system, the confidentiality of the message is ensured by using a symmetric preset key, and the integrity and non-repudiation of the message are ensured by the signature of the asymmetric key digital certificates of both communication parties.
For example: the sender encrypts the message plaintext by using the SM4 preset key to generate a ciphertext and sends the ciphertext to the receiver; and after receiving the information, the receiver decrypts the information by using the corresponding preset key to obtain the message.
If integrity and non-repudiation are required, the implementation of a signature protection mechanism based on an asymmetric digital certificate such as SM2 can be supported.
For example: the sender signs the message (plaintext, ciphertext, plaintext + ciphertext) by using a private key of the sender, and puts the signature and the message to the receiver together; after the receiver receives the information, the integrity and non-repudiation of the information can be verified by using the public key certificate of the sender to verify the validity of the signature.
If the verification is successful, the received information is considered to be complete and is not modified in the transmission process, otherwise, the information is modified.
From the perspective of security protection, the requirements of data transmission privacy, integrity, non-repudiation and non-forgery are met.
The management work of the financial security metering device and the wallet account number mainly comprises functions of legality authentication, on/off-line state and abnormity monitoring, control instruction issuing, metering data reporting, financial currency transaction reconciliation and the like.
In a fourth aspect, the present application provides a storage medium, on which a computer program is stored, where the computer program is executed by a processor to implement the financial security metering apparatus of the first aspect or the financial security metering method of the third aspect.
In a fifth aspect, an embodiment of the present application provides an electronic device, including a memory and a processor, where the memory stores a computer program running on the processor, and the processor implements the financial security metering apparatus of the first aspect or the financial security metering method of the third aspect when executing the computer program.
