PHYSICAL UNCLONABLE FUNCTION FAILURE PROTECTION AND PREDICTION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17725178 Titled 'PHYSICAL UNCLONABLE FUNCTION FAILURE PROTECTION AND PREDICTION'
Simplified Explanation
This abstract describes a method used by a memory device to generate a unique value called a physical unclonable function (PUF). The memory device stores a protection key for the PUF in a memory region that cannot be accessed by the host. The PUF value is then encrypted using the protection key, resulting in an encrypted PUF value. This encrypted value is stored in various locations within the non-host-addressable memory region.
Original Abstract Submitted
In some implementations, a memory device may generate a physical unclonable function (PUF) value. The memory device may access a PUF protection key stored in a non-host-addressable memory region. The memory device may encrypt the PUF value, using the PUF protection key, to generate an encrypted PUF value. The memory device may store the encrypted PUF value in scattered memory locations in the non-host-addressable memory region.
