2018 Cryptography  
To address this issue, the Row Hammer PUF has been proposed by Schaller et al., which leverages the row hammer effect in DRAM modules to reduce the retention times of their cells and, therefore, significantly  ...  As our results prove, the Row Hammer PUF could potentially provide an adequate level of security for Commercial Off-The-Shelf (COTS) devices, if its dependency on temperature is mitigated, and, may therefore  ...  This paper extends the work of Schaller et al., demonstrating that the row hammer effect can be utilised to provide run-time accessible cryptographic applications and improved security.  ...
