Abstract

The invention discloses an encrypting and authenticating equipment with dual safety chips, belonging to the technical field of identity authentication. The equipment comprises a shell, a USB plug outside the shell, a first safety chip, a second safety chip and a radio-frequency antenna, wherein the first safety chip, the second safety chip and the radio-frequency antenna are encapsulated in the shell; the first safety chip is connected with the USB plug, is connected with the second safety chip in the shell, and is also connected with an external system host computer by the USB plug; the second safety chip is connected with the radio-frequency antenna and is connected with a radio-frequency receiving terminal by the radio-frequency antenna; and the first safety chip and the second safety chip carry out communication with each other by an I / O interface. In the invention, two safety chips are used, the two safety chips are internally embedded in an intelligent card embedding software system respectively, thus realizing one corresponding application respectively; and the mutual independence of the two safety chips is effectively ensured, the safe and convenient multi-application formsare realized, furthermore, the two safety chips can realize the safe communication by the I / O interface.

Description

technical field [0001] The invention relates to the technical field of identity authentication, in particular to a double security chip encryption authentication device. Background technique [0002] At present, due to the advantages of high security, convenient use, and portability, cards have been widely used in fields such as finance, tax control, communications, petroleum, medical care, entertainment, etc., and subsequently produced contactless cards, dual-interface cards, CPU Cards and many other forms of cards. In recent years, smart cryptographic keys, as an identity authentication product, have been widely used in online banking, e-government and other activities, and are currently the most widely used personal information security tools that meet the requirements of commercial cryptographic products. [0003] In order to enhance the versatility and flexibility of the two products of cards and smart password keys, many different forms of cards and smart password key...
