Mobile phone Bluetooth KEY capable of performing authentication and encryption and decryption and authenticating and encrypting and decrypting method thereof

Abstract

The invention discloses a mobile phone Bluetooth KEY capable of performing authentication and encryption and decryption and an authenticating and encrypting and decrypting method thereof. The mobile phone Bluetooth KEY comprises a card body and an in-card circuit. The in-card circuit comprises a main control MCU chip, a Bluetooth radio frequency chip, a double-interface chip, a Bluetooth radio frequency antenna and a 13.56MHz induction coil antenna. The main control MCU chip is connected with the double-interface chip and the Bluetooth radio frequency chip respectively, and the Bluetooth radio frequency chip is connected with the 13.56MHz induction coil antenna to achieve a payment function of an electronic wallet. The Bluetooth radio frequency chip is connected with the Bluetooth radio frequency antenna to achieve communication with external matched Bluetooth equipment. One or more digital certificates are stored in the double-interface chip to achieve digital certification. By means of the mobile phone Bluetooth KEY and the method, non-contacting micropayment can be achieved, more importantly, the Bluetooth KEY can be matched with a mobile phone, so that a mobile phone safety certification Key function is provided, and the mobile phone mobile payment safety is improved greatly.
