DarkGates: A Hybrid Power-Gating Architecture to Mitigate the Performance Impact of Dark-Silicon in High Performance Processors
Jawad Haj Yahya, Jeremie S. Kim, A. Giray Yaglikci +4
To reduce the leakage power of inactive (dark) silicon components, modern processor systems shut-off these components' power supply using low-leakage transistors, called power-gate…
A Deeper Look into RowHammer`s Sensitivities: Experimental Analysis of Real DRAM Chips and Implications on Future Attacks and Defenses
Lois Orosa, Abdullah Giray Yağlıkçı, Haocong Luo +6
RowHammer is a circuit-level DRAM vulnerability where repeatedly accessing (i.e., hammering) a DRAM row can cause bit flips in physically nearby rows. The RowHammer vulnerability w…
Security Analysis of the Silver Bullet Technique for RowHammer Prevention
Abdullah Giray Yağlıkçı, Jeremie S. Kim, Fabrice Devaux +1
The purpose of this document is to study the security properties of the Silver Bullet algorithm against worst-case RowHammer attacks. We mathematically demonstrate that Silver Bull…
IChannels: Exploiting Current Management Mechanisms to Create Covert Channels in Modern Processors
Jawad Haj-Yahya, Jeremie S. Kim, A. Giray Yaglikci +5
To operate efficiently across a wide range of workloads with varying power requirements, a modern processor applies different current management mechanisms, which briefly throttle…
QUAC-TRNG: High-Throughput True Random Number Generation Using Quadruple Row Activation in Commodity DRAM Chips
Ataberk Olgun, Minesh Patel, A. Giray Yağlıkçı +6
True random number generators (TRNG) sample random physical processes to create large amounts of random numbers for various use cases, including security-critical cryptographic pri…
BlockHammer: Preventing RowHammer at Low Cost by Blacklisting Rapidly-Accessed DRAM Rows
Abdullah Giray Yağlıkçı, Minesh Patel, Jeremie S. Kim +9
Aggressive memory density scaling causes modern DRAM devices to suffer from RowHammer, a phenomenon where rapidly activating a DRAM row can cause bit-flips in physically-nearby row…
