System and method of pairing and authentication

A system and a method of pairing and authentication are provided. A pairing apparatus transmits its device identity information through near range communication. A controllable apparatus generates a key and a first passing authentication code based on device identity information of the pairing and controllable apparatus, and transmits the key and the first passing authentication code. The fist passing authentication code is encrypted based on the key. In response to receiving a second passing authentication code from the pairing apparatus, the controllable apparatus decrypts the second passing authentication code based on the key. If the first passing authentication code is decrypted from the second passing authentication code, the controllable apparatus performs corresponding function according to an instruction code decrypted from the second passing authentication code.
