Embodiment 1

[0055] This embodiment provides a safe financial terminal firmware programming method, such as figure 1 shown, including:

[0056] Step S1. The financial terminal receives the instruction issued by the host computer. When receiving the instruction to establish a safe environment issued by the host computer, execute step S2. When receiving the secure boot download update instruction issued by the host computer, execute step S3. When receiving Step S4 is executed when the application firmware download and update instruction issued by the host computer is received, and step S5 is executed when the secure firmware download update instruction issued by the host computer is received;

[0057] Specifically, in this embodiment, the host computer encapsulates the instruction to be sent into a standard CCID communication instruction and sends it to the financial terminal.

[0058] Step S2, the financial terminal starts the safety detection function, returns a response to the upper comp...

Embodiment 2

[0225] This embodiment provides a financial terminal, such as Figure 7 As shown, it specifically includes: a communication module 11, a safe environment establishment module 12, a storage module 13, a safe boot download and update module 14, an application firmware download and update module 15 and a secure firmware download and update module 16, and the specific functions of the above modules are as follows:

[0226] The communication module 11 is used to receive the instructions for establishing a safe environment, the download and update instructions for safe boot, the download and update instructions for application firmware, and the download and update instructions for secure firmware issued by the host computer; 14. When the application firmware download and update module 15 and the secure firmware download and update module 16 are finished running, a response is returned to the upper computer;

[0227] The safe environment establishment module 12 is used for starting t...

Abstract

The present invention discloses a secure financial terminal firmware programming method and a financial terminal and belongs to the field of financial security. The method comprises: the financial terminal, according to instructions issued by an upper computer, completes establishment of a security environment, downloading and update of a secure boot, downloading and update of application firmware and downloading and update of secure firmware. The financial terminal comprises a communication module, a security environment establishment module, a secure boot downloading and updating module, an application firmware downloading and updating module and a secure firmware downloading and updating module. The secure financial terminal firmware programming method and the financial terminal have the beneficial effects that potential safety hazards of an existing financial terminal firmware programming method can be avoided and safety of a financial terminal product can be improved.

Description

technical field [0001] The invention relates to the field of financial security, in particular to a secure financial terminal firmware programming method and a financial terminal. Background technique [0002] The financial terminal needs to establish a security environment before using it. After the security environment is established, the financial terminal enters a safe operation mode. In this mode, sensitive data such as keys and passwords can be imported. [0003] In the process of implementing the present invention, technicians find that the existing financial terminal firmware programming method has at least the following potential safety hazards: [0004] 1. The code for establishing a secure environment is included in the official firmware. On the one hand, the attacker has the opportunity to re-execute the process of establishing the secure environment. On the other hand, it may also be due to the error or misjudgment of the secure firmware's own code, which may le...
