Data processing device and data processing method

Abstract

The present invention provides a data processing device and a data processing method. The device includes: a first communication unit, which receives first business data from a first identification card, and transmits the data to a monitoring control unit; a second communication unit, which receives For the second business data of the second identity card, the second business data is transmitted to the monitoring control unit, and the monitoring control unit divides the first business data and the second business data into the first operating system data and the second operating system data, and sent to the first processing unit and the second processing unit respectively; the first processing unit processes the first operating system data, and performs data interaction with the external device of the terminal based on the first operating system data; the second processing unit processes the second operating system data, Perform data interaction with the external device of the terminal based on the second operating system data. Through this technical solution, the security of private data can be guaranteed fundamentally while improving the processing speed of data.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a data processing device and a data processing method. Background technique [0002] Traditional dual standby architectures such as figure 1 As shown, there are two Modems, Modem1 and Modem2 can exchange data such as voice service and data service with the CPU. The two Modems share a CPU (mobile phone processor), and process the data in the mobile phone memory (RAM) and mobile phone memory (EMMC) through the CPU, so as to exchange data with external devices and achieve the purpose of controlling peripherals (external devices). [0003] The disadvantages of existing solutions are: [0004] 1. The traditional dual-standby architecture runs dual systems, and uses Trustzone technology to physically isolate the CPU layer to provide a secure execution environment for encrypted data. The actual situation shows that two Modems in the traditional dual-standby archit...

AI Technical Summary

Problems solved by technology

The actual situation shows that two Modems in the traditional dual-standby architecture share one CPU, and all data including voice service data, data service data and other data are processed by the CPU. With the rapid development of smart phones, the amount of data in smart phones is very large Huge, a CPU will lead to significantly slower data processing speed, affecting user experience;

[0005] 2. Although physical isolation is carried out at the CPU layer, all data is processed by one CPU, and the data is easily confused. The security and privacy of important data such as telephone contacts, text messages, security passwords, and bank accounts cannot be effectively guaranteed. , and cannot achieve independent security in the true sense;

[0006] 3. Traditional smartphones only have one RAM and EMMC to process huge data. When the amount of data increases sharply, the stability of RAM and EMMC will be seriously affected. All data mixed together will also affect the security of personal private data; according to experience, RAM and EMCC Data confusion can easily cause mobile phone crashes and affect the security of personal data
