Abstract:
The present invention relates to a method for authenticating a device based on encryption and generating a session key in a communications network between objects, capable of authenticating a device by using only an encryption module in a light device having only the encryption module, and of generating a session key. The method includes a step that a first device and a second device included in a communications network between the objects share a first random number generated by the first device and a second random number generated by the second random number; a step that the first device and the second device generate a first result by calculating the first random number and the second random number by a predetermined operator; and a step that the first device and the second device settle the generation of the session key by encoding the first result to a secret key which the first device and the second device share.
