Abstract

The invention relates to the technical field of information safety, in particular to a device and a method of data communication by storing a digital certificate private key. The device of the data communication by storing the digital certificate private key comprises an audio input / output module, an audio conversion module, a private key management module, a near field communication (NFC) module, a power supply module and a micro-controller, wherein the audio input / output module is used for being connected and communicated with mobile terminal audio and data, the audio conversion module is used for carrying out mutual conversion and decryption processing on the audio and the data, the private key management module is used for carrying out storage through a certificate and a private key and carrying out data invoking and business signature during the process of identity authentication, the certificate and the private key are applied for through public key infrastructure (PKI) / certificate authority (CA), the NFC module is used in data communication at short ranged through the NFC technology, the power supply module is used for supplying power through a mobile terminal, the micro-controller is used for being connected with the modules and carrying out initialization, state transition and powering up of an interface circuit uniformly. According to the device and the method of the data communication by storing the digital certificate private key, a mobile terminal audio port is adopted to carry out data communication and exchange, and the range of application of a digital certificate is enlarged. The device and the method of the data communication by storing the digital certificate private key is suitable for the identity authentication of various application business of mobile internet and capable of improving reliability and credibility of network awareness.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a device and method for storing digital certificate private keys for data communication. Background technique [0002] At present, in order to ensure the security of information interaction, cryptographic devices are usually used to encrypt information interaction. The more well-known cryptographic devices that store digital certificates and private keys, such as smart cards, Ukeys, tokens, etc., these hardware devices pass USB ( Universal serial bus interface) is directly connected to the computer, has the function of password verification, and has the characteristics of reliable high speed. [0003] Ukey is an extremely powerful supplement to the current network security system. It is a security protection product suitable for stand-alone or network applications. The design of UKey is small and exquisite, and it is easy to carry. Its own memory can be used to sto...
