Method and apparatus for configuring connection between devices in communication system

A method of configuring a connection with a first device, by a second device which provides access to a network in a communication system, the method comprising:

• receiving, by a processor of the second device from the first device, a subscribe message for subscribing to the second device, which includes an ephemeral key of the first device for identifying the first device and a random value;
• and
• transmitting, by the processor to the second device, a publish message for indicating that the access to the network is provided, which includes an ephemeral key of the second device for identifying the second device,
• wherein the second device supports a neighbor awareness network (NAN) and is located within a predetermined range from the first device, and
• wherein the ephemeral key of the first device is determined based on a unique identity value of the first device and the random value, and the ephemeral key of the second device is determined based on a unique identity of the second device and the random value being extracted from the subscribe message.

An apparatus for configuring a connection with a second device, which provides access to a network, by a first device in a communication system, the apparatus comprising:

• a transceiver;
• and
• a processor configured to control to:
• discover the second device supporting a neighbor awareness network (NAN) and located within a predetermined range from the first device,
• determine an ephemeral key of the first device based on a unique identity value of the first device and a random value,
• control the transceiver to transmit, to the second device, a subscribe message for subscribing to the second device, which includes the ephemeral key of the first device for identifying the first device and the random value, and
• control the transceiver to receive, from the second device, a publish message for indicating that the access to the network is provided, which includes an ephemeral key of the second device for identifying the second device;
• and
• wherein the ephemeral key of the second device is determined, by the second device, based on a unique identity of the second device and the random value being extracted from the subscribe message.
