Device Signature Based On Trim And Redundancy Information - A simplified explanation of the abstract

This abstract first appeared for US patent application 18515613 titled 'Device Signature Based On Trim And Redundancy Information

Simplified Explanation

The present disclosure describes a device with memory and a processor that can extract bits from integrated circuit (IC) trim and redundancy information, perform a hashing function on the extracted bits to generate hashed bits, and output the hashed bits based on certain criteria.

  • Memory stores IC trim and redundancy information
  • Processor extracts bits, performs hashing function, and outputs hashed bits
  • Memory for IC information can be separate from other device memory
  • Criteria for outputting hashed bits based on statistical properties

Potential Applications

  • Hardware security
  • Data encryption
  • Anti-counterfeiting measures

Problems Solved

  • Protecting IC trim and redundancy information
  • Ensuring data integrity
  • Preventing unauthorized access to sensitive information

Benefits

  • Enhanced security
  • Efficient data processing
  • Improved reliability of devices


Original Abstract Submitted

The present disclosure describes embodiments of a device with memory and a processor. The memory is configured to store integrated circuit (IC) trim and redundancy information. The processor is configured to extract bits from the IC trim and redundancy information, perform a hashing function on the extracted bits to generate hashed bits, and in response to statistical properties of the hashed bits meeting one or more criteria, output the hashed bits. In some embodiments, the memory that stores the IC trim and redundancy information can be different from other memory used by the device for other operations (e.g., accessing user data and program data that have been written into system memory).
