SYSTEM-ON-CHIP AND ELECTRONIC DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18219955 titled 'SYSTEM-ON-CHIP AND ELECTRONIC DEVICE INCLUDING THE SAME
Simplified Explanation
The patent application describes a system-on-chip that includes a host CPU and a secure element. The secure element consists of a primary device that transmits encrypted data, an internal bus that transmits the encrypted data, multiple secondary devices that receive the encrypted data, and a secure CPU that manages access keys for authorizing the primary device to access the secondary devices. The internal bus determines which secondary device should receive the encrypted data based on the access key and transmits the data to the selected secondary device using an error detection tag.
- The system-on-chip includes a host CPU and a secure element.
- The secure element comprises a primary device, an internal bus, multiple secondary devices, and a secure CPU.
- The primary device transmits encrypted data.
- The internal bus transmits the encrypted data.
- The secondary devices receive the encrypted data.
- The secure CPU manages access keys for authorizing the primary device to access the secondary devices.
- The internal bus selects a secondary device to receive the encrypted data based on the access key.
- The encrypted data is transmitted to the selected secondary device using an error detection tag.
Potential applications of this technology:
- Secure communication systems
- Data encryption and transmission in IoT devices
- Secure payment systems
- Digital rights management
Problems solved by this technology:
- Ensures secure transmission of encrypted data
- Manages access keys for authorized device communication
- Prevents unauthorized access to sensitive information
Benefits of this technology:
- Enhanced security for data transmission
- Efficient management of access keys
- Protection against unauthorized access and data breaches
Original Abstract Submitted
Provided is a system-on-chip including a host central processing unit (CPU) and a secure element, wherein the secure element includes a primary device configured to transmit encrypted data, an internal bus configured to transmit the encrypted data, a plurality of secondary devices configured to receive the encrypted data, and a secure CPU configured to manage access keys indicating authorization of the primary device for accessing the plurality of secondary devices, and the internal bus sets a secondary device to which the encrypted data is to be transmitted from among the plurality of secondary devices, based on the access key and transmits the encrypted data to a set secondary device by using an error detection tag.
