Hardware security module, security terminal and realizing method of security terminal

Abstract

The invention relates to the communication field and discloses a hardware security module, a security terminal and a realizing method of the security terminal. According to the hardware security module, the security terminal and the realizing method of the security terminal of the invention, the hardware security module is integrated on any supporting assembly of a terminal and is used for encrypting or decrypting transmitted and received information of the terminal equipment; the hardware security module supports near field communication (NFC); and the hardware security module encrypts or decrypts the transmitted and received information of the terminal equipment through a near field communication (NFC) channel which is built between the hardware security module and the terminal equipment. With the above technical schemes adopted, under the premise that the structure of a machine of an original type is not modified, a simple and universal method is adopted to transform the machine into the security terminal, and the terminal equipment is not required to be modified in structure, and therefore, cost can be decreased; preferably, information transmitted by a terminal main body and the hardware security module in the near field communication (NFC) channel is a ciphertext which is encrypted by a transmission key, and therefore, hazards that data are stolen can be further avoided, and guarantee can be provided for the security of the security terminal.

Description

technical field [0001] The invention relates to the field of communication, in particular to the field of safe and confidential terminals. Background technique [0002] At present, a security terminal using a hardware security module generally uses an SDIO interface for data interaction. The hardware form of the security module also appears in the form of an SD (Standard Definition, standard definition) card to adapt to the form of the terminal interface. The size of a typical SD card is as figure 1 shown. [0003] However, as the thickness of smart terminals is getting smaller and smaller, and the volume requirements are getting more and more precise, SD cards are obviously not suitable for today's structure. This is because, to independently develop a slot for it, it will also affect the structure of the mobile phone. Moreover, many terminals remove the SD card slot by increasing the capacity of their own built-in memory during design, such as smart machines such as IP...

AI Technical Summary

Problems solved by technology

This means that when changing from an ordinary smart terminal to a security terminal, the terminal structure must be modified, such as adding an SD slot, and for small batch trial production, a full set of mobile phone film and hardware needs to be independently opened, and the production cost is very high.
