Information safety appliance based on MMC / SDIO interface and communication method

Abstract

An information safety device makes software copyright protection and information safety based on MMC / SDIO possible by applying CPU to process data and by connecting chip having MMC / SDIO interface, CPU and storage to host with MMC / SDIO interface for communication. The safety device is small in size and low in power consumption so it can be used in hot insertion way as well as in plug and play way.

Description

technical field [0001] The invention relates to the design of an information security device and a communication method, in particular to an information security device based on an MMC / SDIO interface and a communication method thereof. technical background [0002] In today's increasingly developed information technology, the security and confidentiality of data information are increasingly valued by people. Among them, software copyright protection products, as an information security device, play an important role in the field of software copyright protection. It protects the interests of software developers, increases revenue, protects the interests of legitimate users, and can also control software distribution. At the same time, with the development of the Internet, more and more information involving personal privacy and business secrets needs to be transmitted through the network, and the importance of information security is increasingly recognized by people.
