Native Ternary Random Numbers Generation

Description

This technology provides a system and method for random number generation with physical unclonable functions (PUFs). A plurality of parameter values is generated by inspecting a plurality of cells in a memory array, an average parameter value is determined for each associated cell in the array, and a plurality of unstable cells is identified. Each unstable cell is associated with a parameter value within a threshold value of the average parameter values, and a processor is configured to perform the step of generating the parameter value by measuring a physical attribute of a PUF. Next, first, second, and third groups of cells, among the plurality of unstable cells, are determined by the associated parameter values. A data stream including a plurality of trinary values is generated using the three groups of cells. The processor is further configured to perform the steps of combining the plurality of trinary values, eventually generating a random output value.
