Security module and payment terminal

Abstract

The invention provides a security module and a payment terminal. The security module comprises a security module body, a security chip unit, an expansion chip unit and an interface unit, a security chip unit configured to install a security chip; an expansion chip unit configured to mount an expansion chip; and the interface unit is configured to perform information interaction with the main control module. According to the application, the security module body, the security chip unit, the expansion chip unit and the interface unit are integrated into one security module, and the security module is installed in the payment terminal, so that when the payment terminal is upgraded, only the control chip needs to be replaced, the security module does not need to be replaced, and the consumption of the chip is saved. And meanwhile, the security chip unit and the expansion chip unit are detachably mounted in the security module body, and the security chip or the expansion chip can be selectively replaced according to requirements, so that the updating speed of the security module and the payment terminal is high, the updating period is short, and the market requirements can be quickly responded.

Description

technical field [0001] The present application belongs to the technical field of payment terminals, and in particular relates to a security module and a payment terminal. Background technique [0002] The security chip is a device that can independently generate, encrypt and decrypt keys, and has an independent processor and storage unit inside, which can store keys and characteristic data. Encrypted with a security chip, the key is stored in hardware, and the stolen data cannot be decrypted, thus protecting business privacy and data security. [0003] Generally, a security chip and a control chip are fixedly installed in a payment terminal, wherein the security chip is used to protect confidential information. With the continuous updating and iteration of technology, when updating the payment terminal, the control chip and the security chip are generally replaced together. However, with the gradual tightening of the global chip supply, the product release cycle and update ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of this application is to provide a security module and a payment terminal, which aims to solve the problem that the traditional security module needs to be replaced frequently, which leads to a long update cycle of the payment terminal and cannot respond to market demand
