Abstract: A method for establishing a resource access authorization in M2M communication is provided. When an entity including a terminal, a gateway and an end user as client in a first M2M service provider domain attempts to access resource located in terminal or gateway in second M2M service provider domain, the method includes receiving client credential allocated from M2M Authentication Server (MAS1) in first M2M service provider domain by performing client registration to Network Service Capabilities Layer (NSCL1) in first M2M service provider domain by client, requesting an authorization to access resource to resource owner through NSCL (NSCL2) in second M2M service provider domain based on information about Universal Resource Identifier (URI) of resource by client, verifying client through MAS1 by the resource owner, authorizing client to access the resource by the resource owner, and issuing access token to the client by MAS (MAS2) in second M2M service provider domain.

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.
