| description | Provided is a security authentication method of a network video recorder (NVR) including assigning a terminal unique index to each of pseudo-random functions included in a pseudo-random function set using terminal information; transmitting a session key having a predetermined expiry time and the pseudo-random function set with the assigned terminal unique index to a terminal; calculating a first terminal unique index for authenticating a first message using a predetermined bitstream of the first message received from the terminal; selecting a first pseudo-random function for authenticating the first message using the calculated first terminal unique index; generating a first independent private key of the terminal for authenticating the first message by inputting the session key and a MAC address of the terminal to the first pseudo-random function; and generating a message authentication code for the first message using the first independent private key and authenticating the first message. |
