Problems solved by technology

[0008] However, if the sensor device does not have a sufficient security function, it may receive unauthorized access from the outside through the LPWA, which may cause data leakage, tampering, or be used as a stepping stone to unauthorized access to other network devices. and other issues

no. 2 Embodiment approach

[0104] In the second embodiment, in the storage unit 22 of the gateway device 5 ( image 3 ), the communication method setting condition, which is the condition for determining the communication method of each sensor device 6, is used as the Figure 4 corresponding Figure 11 The communication method setting table T3 shown is stored.

[0105] In this communication method setting table T3, "DoS detection function" and "communication method" are prepared as items, and "Yes" or "No" is stored as a value of "DoS detection function", which is used for each DoS detection function. The value of "communication method" associated with the function stores "LPWA" or "FAN". That is, in the communication method setting table T3, "having a DoS detection function" is specified as a security condition for specifying the communication method as LPWA.

[0106] Furthermore, in the second embodiment, as with Figure 5 (A) and (B) correspond to Figure 12 As shown in (A) and (B), although the...

no. 3 Embodiment approach

[0122]In the third embodiment, in the storage unit 22 of the gateway device 5 ( image 3 ), the communication method setting condition, which is the condition for determining the communication method of each sensor device 6, is used as the Figure 4 and Figure 11 corresponding Figure 15 The communication method setting table T5 shown is stored.

[0123] In this communication method setting table T5, as two major classifications, "DoS detection function" and "data type" columns are prepared, and further, as a sub-category of "DoS detection function", "Yes" or "No" is prepared. " column, as a subcategory of "type of data", columns of "temperature / humidity" and "image / sound" are prepared.

[0124] In addition, in the communication method setting table T5, only the combination of "DoS detection function" is "Yes" and the "data type" is not "image / sound" (that is, "temperature / humidity"). LPWA" as the "communication method", and "FAN" is stored in other combinations. That is...

Abstract

The invention provides a sensor management system, a sensor management method, and a sensor management device, which can ensure security and determine a communication mode applicable to a sensor device. In the sensor management system, the communication mode is determined by employing a gateway device according to the presence of a safety function of the sensor device. Namely, the communication mode of the sensor device with the safety function is set as LPWA, the safety is ensured by employing a safety processing unit of the sensor device, and the processing load of the gateway device is reduced. Furthermore, the communication mode of the sensor device without the safety function is set as FAN, the safety can be ensured by employing the safety processing unit of the gateway device in a state of maintaining a simple structure. Therefore, in the sensor management system, sensing data can be safety transmitted from each sensor device, and external attacks through the Internet can be handled.

Description

technical field [0001] The present invention relates to a sensor management system, a sensor management method, a sensor management program, and a sensor management device, and is preferably applied to, for example, sending data collected by sensors to a server via a network. Background technique [0002] In recent years, a framework called IoT (Internet of Things, Internet of Things) has been proposed in which various items are connected to a network, and various information obtained from each item is exchanged with each other, thereby controlling each other. In addition, it is proposed to store a huge amount of information obtained through IoT in a server or the like as so-called big data and use it for various purposes. [0003] In this IoT, a sensor device that collects data may be equipped with a wireless communication function, and a gateway device having a wireless communication function corresponding to the wireless communication function may be installed, thereby ma...
