US 2014/0317707 A1 · METHOD FOR SHARING DATA OF DEVICE IN M2M COMMUNICATION AND SYSTEM THEREFOR

Abstract

The present invention relates to a method for sharing data of a device in M2M communication and a system therefor. The invention comprises: a step of allowing a resource user terminal to request access authority of protected resource data to a resource owner terminal, in order to prevent a security threat; a verification step of allowing the resource owner terminal to verify the resource user terminal to request the setting of the access authority to an M2M server, and to transmit a verification key issued from the M2M server to the resource user terminal; an access authority setting step of allowing the M2M server to generate an access authentication key based on the verification key, and to transmit the access authentication key to the resource user terminal; and a using step of allowing the resource user terminal to inquire about the protected resource data from the M2M server based on the access authentication key, and to use the protected resource data.

Dependent claims

A method of sharing data between devices in M2M communication, the method comprising:

an access right request step of requesting, by a resource user terminal, a right to access protected resource data to be shared from a resource owner terminal based on information about the protected resource data;
a verification step of verifying, by the resource owner terminal, the resource user terminal, requesting, by the resource owner terminal, an M2M server to set the access right of the resource user terminal, and sending, by the resource owner terminal, an verification key (an access right ID) issued by the M2M server to the resource user terminal;
an access right setting step of generating, by the M2M server, an access authentication key based on the verification key transmitted by the resource user terminal, and sending, by the M2M server, the access authentication key to the resource user terminal;
and
a usage step of requesting, by the resource user terminal, a search for the protected resource data through the M2M server based on the access authentication key, and using, by the resource user terminal, the protected resource data.

2 more elements

A system for sharing data between devices in M2M communication, the system comprising:

a resource owner terminal configured to generate protected resource data;
a resource user terminal configured to request a the right to access the protected resource data to be shared from the resource owner terminal based on information about the protected resource data;
and
an M2M server configured to store the protected resource data, to generate a verification key (an access right ID) in response to a request from the resource owner terminal, to send the verification key to the resource user terminal, to generate an access authentication key in response to a request from the resource user terminal based on the verification key, to send the access authentication key to the resource user terminal, and to send the protected resource data to the resource user terminal when the resource user terminal requests a search for the protected resource data based on the access authentication key.
