Embodiment Construction

[0017] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are exemplified below and described in detail with accompanying drawings.

[0018] Please refer to figure 1 , figure 1 It is a structural diagram of the embedded system of the present invention.

[0019] The embedded system 1 of the present invention includes a control system 10 , an In System Programming (ISP) module 20 and an external storage module 30 , which are electrically connected to each other. The control system 10 is structured using a System On Chip (SOC), a Multi-chip Package (MCP) or a System In Package (SIP), but the present invention does not This is not the limit. The control system 10 includes a processing module 11 , a first storage module 12 , a second storage module 13 and a third storage module 14 , which are electrically connected to each other. If the control system 10 is a SoC, the processing module 11 , t...

Abstract

The invention relates to a control system, a security check method and an embedded system. The control system is used for the embedded system to execute the security check method. The control system comprises a processing module and a first storage module, and the first storage module is electrically connected with the processing module and is used for storing a preloading code and a first security key, wherein when the control system is connected with a programming module in the system, the processing module utilizes the preloading code to read a first application program of the programming module in the system so as to judge whether the first application program conforms to the first security key; if yes, then a second application program of the programming module in the system is executed to establish an internal program and a second security key. The invention can realize the security of the embedded system without limiting the expansibility of the embedded system applying the control system and the security check method.

Description

technical field [0001] The invention relates to a control system and a safety inspection method, in particular to a control system and a safety inspection method suitable for an embedded system. Background technique [0002] In today's life, embedded systems have been widely designed and applied in various occasions, such as automatic teller machine (Automatic Teller Machine, ATM) system or personal digital assistant (Personal Digital Assistant, PDA) system. In order to save manufacturing costs, a control system applicable to various embedded systems has been developed in the prior art. With different interfaces and application programs, the control system can become an embedded system for different purposes. [0003] Since the control system is applicable to various interfaces and application programs, a security checking method is needed to protect the control system from being damaged by unknown interfaces or application programs. [0004] In order to avoid the above de...
