Embodiment Construction

[0026] Hereinafter, the configuration and operation of preferred embodiments of the present invention will be explained with reference to the accompanying drawings.

[0027] The present invention is conceptually related to when a certain DM server sends a bootstrap message to a certain device, by utilizing a cryptographic signature (or certificate) shared by the certain DM server and the user's integrated circuit (IC) card (e.g., SC: smart card) ) to safely send the bootstrap message. The present invention is also conceptually related to verifying that a device determined to have received a bootstrap message (e.g., a packet type including a cryptographic signature and bootstrap information) from a determined DM server by utilizing authentication information (e.g., a cryptographic signature or certificate) of a smart card. message) while allowing the bootstrapping of certain devices.

[0028] Here, the signature is used for authenticating the DM server by the device, and for a...

Abstract

A method and device for securely sending a bootstrap message from a server (i.e., a device management (DM )server) to a device in a device management system, the method comprising acquiring first information by the device, receiving, by the device, a bootstrap message from the server, acquiring, by the device, second information from the received bootstrap message, and verifying the bootstrap message by the device, whereby it is effective to securely send the bootstrap message from the server to the device by checking up whether the first information is identical to the second information.

Description

technical field [0001] The present invention relates to device management (DM), and more particularly, to a method and apparatus for securely sending bootstrap messages in a DM system. Background technique [0002] In general, a DM system makes it possible to change settings of a device by remotely controlling variables or values ​​of objects stored in a specific device by a third party using an effective method. [0003] The DM system according to the prior art is implemented such that a DM server transmits a command related to a specific management object (MO) existing within a device, and a DM client that has received the command executes the corresponding command. Here, the MO typically exists in the device's database and logically connects nodes on the DM tree that also exist within the device. That is, the DM server accesses a node logically connected to the MO to desirably access via a Universal Resource Indicator (URI), thereby transmitting a management command on t...
