A mobile phone headset based on puf authentication and information encryption

Abstract

The invention relates to a mobile phone earphone based on PUF identity authentication and information encryption. The mobile phone earphone based on PUF identity authentication and information encryption is characterized in that a PUF module is arranged between an earphone audio interface and an earphone loudspeaker and is inlaid in the mobile phone earphone; the PUF module comprises an energy collector, a duplex communicator, a static storage, an error correction decoder and an encrypted circuit; the energy collector, the duplex communicator and the earphone audio interface are connected; the energy collector obtains voltage and current through the audio interface and supplies power to other modules after processing the voltage and the current; the duplex communicator is in intercommunication with a mobile phone through the earphone audio interface, and is further connected with the static storage and the encrypted circuit; the static storage is connected with the error correction decoder; the error correction decoder is connected with the encrypted circuit; the encrypted circuit is connected with the earphone loudspeaker. By the adoption of the PUF technology, the safety problem of an existing encryption algorithm is solved through hardware encryption, and the mobile phone earphone becomes a special device for identity authentication, information encryption and payment security enhancement.

Description

technical field [0001] The invention belongs to the technical field of information encryption, in particular to a mobile phone earphone based on PUF authentication and information encryption. Background technique [0002] Mobile phone earphones are a common external component of mobile phones. With the development of smart phones, mobile phones have carried more entertainment functions, showing multimedia features. In addition to the need to reduce call radiation, mobile phone earphones have gradually become the s things. With the popularization of smart phones and the development of 3G and 4G technology, the application of identity verification or cardless payment through mobile phones is becoming more and more extensive. In the field of existing mobile phone card-free payment, software methods such as secret-related transaction methods or security algorithms are usually used to realize it, which generally has the problems of poor security, complicated operation process, a...
