1. A method of providing service for a machine-to-machine (M2M) device, the method comprising:
- transmitting, a request for service to a network entity providing a security capability;
performing an authentication with an M2M authentication server (MAS) via the network entity;
generating, if the authentication is successful, a service key based on a master session key (MSK), a first constant string, and an identification associated with the M2M device;
transmitting a message indicating registration result acknowledgement to the network entity, comprising a value for a lifetime requested for the registration; and
generating an application key based on the service key, a second constant string, and an application identification (ID).

Abstract
A method and an apparatus for providing Machine-to-Machine (M2M) service are provided. A method of providing service by an M2M device includes transmitting a request for service to a Network Security Capability (NSEC), the request for service comprising a identifier of a Device Service Capability Layer (DSCL) of the M2M device, performing an Extensible Authentication Protocol (EAP) authentication with an M2M Authentication Server (MAS) via the NSEC, and generating, if the EAP authentication is successful, a service key using a Master Session Key (MSK), a first constant string, and the identifier of the DSCL.
