Abstract

A device for processing and storing data is disclosed, which comprises a primary controller, a primary memory, a security element (SE), and at least one universal port, wherein the device for processing and storing data further includes a first additional port, via which the security element (SE) can directly interacts with a second external device to complete the processing and access of the data. The security element (SE) in the device for processing and storing data disclosed herein can work independently without being effected by the condition whether the primary memory is performing the data read/write process, and supports the single wire protocol (SWP).

Claims

1. A device for processing and storing data, the device comprising:

a primary controller;

a primary memory;

a security element (SE) configured to operate independently without being effected by data read/write processes performed in the primary memory and to expand mobile payment applications;

at least one universal port, wherein based on a first communication protocol, the primary controller controls the primary memory and/or the security element (SE) to interact with a first external device via the at least one universal port so as to complete the processing and access of the data, wherein the at least one universal port includes a plurality of pins; and

a first additional pin, via which the security element (SE) interacts with a near-field communication (NFC) controller chip of a second external device based on a second communication protocol to complete the processing and access of the data, wherein the second communication protocol is single wire protocol (SWP).

2. The device for processing and storing data of claim 1, further comprising:

a second additional pin, via which the security element (SE) is powered, wherein the first and second additional pins are separate from the plurality of pins included in the at least one universal port.

3. The device for processing and storing data of claim 2, characterized in that, the first communication protocol is secure digital (SD) card interface protocol.

4. The device for processing and storing data of claim 3, characterized in that, the at least one universal port includes 8 contacts PIN1-8 defined in secure digital (SD) card interface protocol.

5. The device for processing and storing data of claim 4, characterized in that, the first external device is a baseband chip in a mobile device.

6. The device for processing and storing data of claim 5, characterized in that, security element (SE) processes and stores the security information data, and wherein the processing includes data-based operations.

7. The device for processing and storing data of claim 6, characterized in that, the primary memory is a FLASH memory.

8. The device for processing and storing data of claim 7, characterized in that, the device for processing and storing data has a shape of a normal SD card.

9. The device for processing and storing data of claim 8, characterized in that, the 8 contacts PIN1-8 are arranged in a row, while the first additional pin and the second additional pin are arranged in another row.

10. A mobile terminal including the device for processing and storing data according to any of claim 1, 2, 3-5, or 6-9.
