The embodiment of the invention provides a method for upgrading a transaction terminal, as shown in FIG. 1 , wherein:

Step S101, reporting an upgrade request of the transaction terminal to the server, where the upgrade request includes an identifier of the variable component in the transaction terminal;

Step S102: Receive update program information delivered by the server, where the update program information includes upgrade information of the variable component that the transaction terminal needs to upgrade, and the transaction terminal included in the update program information needs to be upgraded. The number of variable components is not greater than the number of identifiers of the variable component included in the transaction terminal in the upgrade request;

Step S103: Update the corresponding variable component according to the upgrade information included in the update program information.

In the above embodiment of the present invention, the variable component refers to a component that can be updated in the transaction terminal, for example, a component that processes the card swipe operation in the transaction terminal system, or a component that reads the IC card. The variable component, in addition to the variable component, has a fixed component in the transaction terminal system. The fixed component is a component that does not need to be updated in the transaction terminal system. For example, a component capable of supporting a normal switching machine of the transaction terminal can be classified into a fixed component.

In the above embodiment of the present invention, the transaction terminal may be a smart sales terminal POS machine, It may be an ATM (Automatic Teller Machine) in a bank, or a Lakka credit card machine installed in a different convenience store. In the present invention, the transaction terminal refers to a smart POS machine.

In the step S101, the upgrade request refers to a type of request sent by the system of the transaction terminal to the server that needs to perform system update after the transaction terminal is powered on, and the upgrade request includes all the transactions in the transaction terminal. The identification number of the variable component, which can be the ID number of all variable components.

In the step S101, the upgrade request further includes:

If the server is connected to the plurality of transaction terminals, the transaction terminal reports to the server that the transaction terminal information may be an identification ID number of the transaction terminal, so that the server searches for the corresponding variable according to the identification ID of the transaction terminal. Component area.

The version number of all variable components in the transaction terminal is reported to the server, so that when the server receives the upgrade request, the variable component is searched according to the ID number of the variable component, and then saved according to the version number of the variable component reported. The version number of the variable component in the server is compared. If it is inconsistent, it indicates that the variable component needs to be updated.

In the step S101, the reporting period may be set in advance. For example, if the update period is set to one week, the transaction terminal will connect to the server at a specific time every week, and report the upgrade request, which may be implemented in the implementation. The length of the update cycle can be automatically adjusted according to the requirements, or it can be set manually.

Wherein, in step S102, the number of the variable components that need to be upgraded by the transaction terminal included in the update program information is not greater than the identifier of the variable component included in the transaction terminal in the upgrade request. quantity.

This small binary value is called a hash value. MD5 is an industry-standard one-way 128-bit hash scheme developed by RSA Data Security. The role of MD5 is to enable large-capacity information to be "compressed" into a secure format before signing a private key with digital signature software. Converts a byte string of arbitrary length into a string of hexadecimal digits of a certain length. MD5 treats the entire file as a large text message, and generates a unique MD5 message digest by its irreversible string transformation algorithm. Various peer-to-peer protocol vendors use it for encrypted authentication.

In the embodiment of the present invention, the transaction terminal uses an intelligent POS machine as an example to explain that the server sends an update program of the variable component to the smart POS machine, and uses the MD5 value to update the variable component sent by the server to the smart POS machine.

Variable component update program by Two parts, one is the update program of the original variable component, and the other part is the summary information encoded by MD5;

The intelligent POS machine receives the update program of the variable component pushed by the server, first separates the update program of the variable component composed of two parts, and the intelligent POS machine performs the MD5 operation according to the content of the update program of the received variable component. Recalculating the summary information of the update component of the variable component, the smart POS machine compares the summary information calculated by itself with the received summary information, and if the comparison result is the same, it considers that the update component of the variable component is transmitting It has not been modified in the middle. Otherwise, the update procedure of the variable component must be modified during the transmission process, so the content is not trusted.

In step S103, updating the corresponding variable component according to the upgrade information included in the update program information, including:
