In this work we demonstrate that the DD-cell, previously proposed by the authors to implement weak PUFs, can behave also as a TRNG, thus allowing the implementation of PUF and TRNG primitives based on the same entropy source. The proposed architecture has been implemented on a Xilinx Artix-7 FPGA device, and both PUF and TRNG functions have been verified through an extensive measurement campaign involving PVT variations. Measurements results have shown that the entropy of a DD-cell can reach a value higher than 0.99 without requiring any post-processing.

Abstract
In this work we demonstrate that the DD-cell, previously proposed by the authors to implement weak PUFs, can behave also as a TRNG, thus allowing the implementation of PUF and TRNG primitives based on the same entropy source. The proposed architecture has been implemented on a Xilinx Artix-7 FPGA device, and both PUF and TRNG functions have been verified through an extensive measurement campaign involving PVT variations. Measurements results have shown that the entropy of a DD-cell can reach a value higher than 0.99 without requiring any post-processing.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
