Abstract

The invention provides a multi-interface safe key device and a method. The multi-interface safe key device comprises at least two interface modules and a controller, wherein the controller comprises an interface selection module, a storage module and a service processing module. The interface selection module is respectively connected with each interface module, and is used for taking the interface module in a communication-capable state as the current interface module while sensing that one of the at least two interface modules is in the communication-capable state. The storage module is used for storing a private key. The service processing module is respectively connected with the storage module and each interface module, and is used for signing service information received from the current interface module according to the private key to form service request information, and transmitting the service request information through the current interface module. The multi-interface safe key device and the method provided by the invention can process safety of e-commerce services of different smart terminals via a plurality of interfaces, thereby improving compatibility of the safe key device.

Description

technical field [0001] The invention relates to security key device technology, in particular to a multi-interface security key device and method. Background technique [0002] With the gradual deepening of the application of the Internet and business systems, the security protection of online information and business systems has become increasingly prominent. As a security authentication terminal, a USB security key (Universal Serial BUS Key, referred to as USB Key) device is widely used in the fields of bank security and network security. When the user conducts e-commerce business through a personal computer, the USB Key performs data interaction with the personal computer through the USB interface, and digitally signs the transaction data generated during the e-commerce business process to ensure the security of the e-commerce business. [0003] With the widespread application of 3G networks and smart terminals, more and more users conduct e-commerce services through sma...
