Abstract

The invention discloses an audio switching device and a security authentication system. The audio switching device comprises a main control chip, a power source, an audio communication interface, an audio signal processing unit and a USB communication interface, wherein the power source is connected with the main control chip, the audio communication interface is connected with the audio signal processing unit and the audio port of a portable terminal, the audio signal processing unit is connected with the main control chip, the audio communication interface is used for obtaining simulation transaction data, the audio signal processing unit is used for digitalizing the simulation transaction data to generate digital transaction data and transmitting the digital transaction data to the main control chip, and the main control chip works in a host mode so as to convert the digital transaction data into corresponding USB signals, and interacts with a security authentication device through the USB communication interface. With the audio switching device provided by the invention adopted, a security authentication device such as a USBKEY can perform security processing on financial transaction sensitive data on a portable terminal, and therefore, financial transaction security issues under the mobile Internet can be ensured.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to an audio switching device and a security authentication system. Background technique [0002] With the popularity of intelligent mobile terminal equipment and the rapid development of the mobile Internet, online shopping and financial transactions can gradually be realized not only on PCs, but also on mobile terminals. In other words, the degree of mobility of online shopping and financial transactions Higher and higher. [0003] In order to ensure the security of the transaction, the PC must rely on the USBKEY to encrypt and decrypt transaction-related data. Similarly, when conducting transactions on mobile terminals, the traditional USBKEY can be technically expanded to become a security authentication tool that can be used for mobile transactions. [0004] With the development of mobile Internet, the hardware configuration and software functions of p...
