PHYSICAL UNCLONABLE FUNCTION (PUF) SECURITY KEY GENERATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18517801 titled 'PHYSICAL UNCLONABLE FUNCTION (PUF) SECURITY KEY GENERATION
Simplified Explanation
The abstract describes a patent application for generating a security key for an integrated circuit device using a physically unclonable function (PUF) generator. Unstable bits are identified and excluded from the security key generation process.
- Physically Unclonable Function (PUF) generator used to generate key bits
- Unstable bits identified and excluded from security key
- Security key generation process based on stable key bits
Potential Applications
This technology can be applied in:
- Secure authentication systems
- Secure communication protocols
- Secure data storage devices
Problems Solved
- Preventing unauthorized access to integrated circuit devices
- Enhancing security of sensitive information
- Protecting against cloning or counterfeiting of security keys
Benefits
- Improved security for integrated circuit devices
- Enhanced protection of data and communication channels
- Increased resistance to hacking and unauthorized access
Original Abstract Submitted
Systems and methods of generating a security key for an integrated circuit device include generating a plurality of key bits with a physically unclonable function (PUF) generator. Unstable bits of the plurality of key bits are identified, and a security key is generated based on the plurality of key bits, wherein the security key excludes the identified unstable bits.
