Embodiment approach 1

[0034] 1.1 Overview of Embedded Devices

[0035] figure 1 It is a block diagram schematically illustrating an embedded device incorporating the security device according to the first embodiment.

[0036] figure 1 The illustrated built-in device 1000 includes a built-in control device 1020, a built-in control device 1021, a built-in control device 1022, a built-in control device 1023, a control system network 1040, an external connection system network 1060, an external connection system network 1061, and an external connection system network 1062. , a gateway (GW) 1080, a communication interface (I / F) 1100, a communication I / F 1101, and a communication I / F 1102. Embedded device 1000 may include elements other than these elements.

[0037] The embedded device 1000 is installed in mobile objects such as automobiles, home appliances, factory automation (FA) equipment, and the like. Hereinafter, it will be described assuming that embedded device 1000 is an in-vehicle device mo...

Embodiment approach 2

[0114] In Embodiment 1, the execution environment of the main function is configured according to the security risk situation, but the content of the main function is not affected by the security risk situation. In contrast, in Embodiment 2, in addition to configuring the execution environment of the main function according to the security risk situation, the content of the main function is changed according to the content of the security function.

[0115] Hereinafter, the configuration of Embodiment 2 related to the above differences will be described. As for the structures not described, the structures employed in Embodiment 1 are employed as they are or also employed in Embodiment 2 after being modified.

[0116] Figure 9 It is a block diagram schematically illustrating an embedded control device constituting the safety device according to the second embodiment.

[0117] Figure 9 The illustrated embedded control device 1020 includes a main function execution unit 1280...

Abstract

The present invention makes it possible for a built-in control device to suitably execute a security function while suppressing effects on the execution of primary functions. This security device is provided with: an attack detection unit, a security risk status determination unit, and an execution environment control unit. The attack detection unit detects a cyber attack against built-in devicescontrolled by a built-in control device. On the basis of the detection result, the security risk status determination unit determines a security risk status indicating the type of security threats and / or the degree of risk posed by the cyber attack. The execution environment control unit is provided in the built-in control device, and determines a security function against the cyber attack in accordance with the security risk status, and configures the environment of the built-in control device where the security function is to be executed so that the built-in control device can execute the security function.

Description

technical field [0001] The present invention relates to a security device against network attacks against a built-in device controlled by a built-in control device, and a built-in device including the security device. Background technique [0002] Embedded devices are installed in moving objects such as automobiles, home appliances, and factory automation (FA) equipment. Embedded devices are controlled by an embedded control. For example, in-vehicle devices are mounted in automobiles. The on-board equipment is controlled by the vehicle control engine control unit (ECU). [0003] Traditionally, embedded devices have been used independently. However, in recent years, embedded devices are used in a state connected to an external network in response to the trend toward Internet of Things (IoT). [0004] Embedded devices used while connected to an external network may be vulnerable to cyber attacks. Therefore, in recent years, security functions for protecting embedded devic...
