A method for machine-to-machine (M2M) service bootstrapping of an M2M device and a corresponding apparatus are provided. The method comprises transmitting, by the M2M network node server, a first message to an M2M device, the first message comprising a service provider (SP) identifier (ID) and at least one of a usage type, an M2M service bootstrap function (MSBF) ID, a network service capability layer (NSCL) ID, and a target device ID; identifying, by the M2M network node server, whether the M2M device is assigned a service provider assigned device ID; transmitting, by the M2M network node server, a second message to the M2M device after transmitting the first message to the M2M device; and generating, by the M2M network node server, an M2M root key based on the SP ID and the service provider assigned device ID if the second message from the network M2M node includes the service provider assigned device ID based on a result of the identification, wherein the M2M root key is used for mutual authentication between the M2M device and a service provider corresponding to the SP ID, and wherein the generating of the M2M root key comprises generating, if the service provider assigned device ID is not assigned by the network, the M2M root key based on an extended master session key (EMSK), a predetermined string, the SP ID, and the M2M device's own ID.
