Problems solved by technology

However, because the same symmetric key used for both encryption and decryption must be shared between devices performing encryption and decryption operations, IoT systems can potentially be exposed to external threats (e.g., attacks from rogue software)

Embodiment Construction

[0034] Hereinafter, some example embodiments of the inventive concept will be described in detail with reference to the accompanying drawings. Example embodiments may be described with reference to acts and symbolic representations (e.g., in the form of flowcharts, flow diagrams, dataflow diagrams, structural diagrams, block diagrams, etc.) of operations that may be implemented in connection with elements and / or devices discussed in greater detail below. . Although discussed in a specific manner, the functions or operations specified in certain blocks may be performed in a flow other than that specified in a flowchart or flow diagram. For example, functions or operations illustrated to be performed in series in two consecutive blocks may in fact be performed concurrently, concurrently or in some cases in the reverse order.

[0035] A unit and / or apparatus according to one or more example embodiments may be implemented using hardware, a combination of hardware and software, or...

Abstract

The disclosure provides a method and device for verifying integrity by using tree structure. A method of verifying integrity of an Internet of Things (IoT) system including a hub device and a plurality of end-node devices includes: determining, by the hub device, a root device among the plurality of end-node devices; receiving, by the hub device, from the root device at least one root message authentication code generated based on a result of verifying integrity of a sub-tree of the root device, wherein the sub-tree of the root device comprises a subset of the plurality of end-node devices subordinate to the root device; and verifying, by the hub device, the at least one root message authentication code.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2017-0116659 filed with the Korean Intellectual Property Office on September 12, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The inventive concept relates to a method of verifying the integrity of a system, and more particularly, to a method and apparatus for verifying the integrity by using a tree structure and a symmetric key. Background technique [0004] Due to the development of information technology (IT), various pieces of data are newly generated, and more data to be protected such as personal information is added. Various threats to data have also become diverse and intelligent, requiring advanced encryption technology to protect various data. In order to protect the system from external security threats, authentication of devices using encryption techniques, integrity verifi...
