Trusted computing platform chip applicable to mobile communication equipment and authentication method thereof

Abstract

The invention relates to a trusted computing platform chip applicable to mobile communication equipment and an authentication method thereof. The trusted computing platform chip is provided with a secret key generating module based on a public key infrastructure (PKI) system, a data high-speed encrypting and deciphering engine module, a data safe memory module, a chip physical protection module, a fingerprint processing engine module, a small computer system interface (SCSI) interface module and a near field transmission module, wherein the SCSi interface module and the near field transmission module support the operation of a subscriber identity module (SIM) card; the fingerprint processing engine module, the SCSI interface module and the short-distance transmission module are connected with a communication bus; and the chip is encapsulated into an SIM card form or a trusted platform module (TPM) form. The trusted computing platform chip has the advantages that a TPM technique is combined with a fingerprint identification technique; the TPM technique is combined with mobile payment; the function of the TPM and mobile site payment is realized in one chip by a near field communication technique; the transaction security is simultaneously enhanced by adding the fingerprint technique; and the remote payment is realized by combining a wireless application protocol (WAP) 2.0 technique.

Description

technical field [0001] The present invention relates to the fields of information security, mobile payment and biometrics, especially a trusted computing platform chip and its authentication method applicable to mobile communication equipment. By integrating the technologies in the three fields, an innovation is realized. Innovative products, can be widely used in mobile payment and security computer occasions. Background technique [0002] Mobile payment is one of the manifestations of modern electronic payment. It is a mobile value-added service that provides payment services through mobile phones. Commercial activities such as bank transfer, bill payment and shopping can be completed through mobile payment. Mobile payment includes online remote mobile payment and contactless mobile payment. Contactless mobile payment means that users use mobile phones and POS terminals to complete payment in a non-contact way through near-site communication technology at the consumption...

AI Technical Summary

Problems solved by technology

[0014] The existing mobile payment methods are low in security and can only be used for small-amount payments. Without using PKI technology, remote payment cannot be performed.
