SECURITY IC AND OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17984591 titled 'SECURITY IC AND OPERATING METHOD THEREOF
Simplified Explanation
The abstract describes a security integrated circuit (IC) that includes a memory, a token generation circuit, and an error detection circuit. Here is a simplified explanation of the abstract:
- The security IC has a memory with two registers - a first register and a second register.
- A token generation circuit is present in the IC, which performs various operations.
- Before performing an operation, the token generation circuit extracts specific bits of interest from the first register and generates first data based on those bits.
- The first data is then converted into a first token by the token generation circuit.
- After performing the operation, the token generation circuit extracts different bits of interest from the second register and generates second data based on those bits.
- The second data is then converted into a second token by the token generation circuit.
- An error detection circuit is included in the IC, which compares the first token with the second token to detect any errors on the bits of interest.
Potential applications of this technology:
- Secure communication systems
- Secure data storage devices
- Authentication systems
- Secure payment systems
Problems solved by this technology:
- Ensures the integrity of data by detecting errors on specific bits of interest.
- Provides a secure method for generating tokens based on extracted data.
- Enhances the security of integrated circuits by incorporating error detection mechanisms.
Benefits of this technology:
- Improved security and protection against data tampering or unauthorized access.
- Efficient error detection and prevention of data corruption.
- Enhanced reliability and trustworthiness of integrated circuits.
Original Abstract Submitted
A security integrated circuit (IC) includes a memory including a first register and a second register, a token generation circuit configured to generate first data based on first bits of interest extracted before performance of an operation by using the first register, generate a first token by converting the first data, generate second data based on second bits of interest extracted after the performance of the operation by using the second register, and generate a second token by converting the second data, and an error detection circuit configured to detect an error on the first and second bits of interest by comparing the first token with the second token.
