Security Research: Technical Paper Round-Up


A number of hardware security-related technical papers were presented at recent conferences, including the August 2022 USENIX Security Symposium and IEEE’s International Symposium on Hardware Oriented Security and Trust (HOST). Topics include side-channel attacks and defenses (including on-chip mesh interconnect attacks), heterogeneous attacks on cache hierarchies, rowhammer attacks and mitig... » read more

An Escalation of Rowhammer To Rows Beyond Immediate Neighbors


Researchers at Graz University of Technology, Lamarr Security Research, Google, AWS, and Rivos presented this new technical paper titled "Half-Double: Hammering From the Next Row Over" at the USENIX Security Symposium in Boston in August 2022. Abstract: "Rowhammer is a vulnerability in modern DRAM where repeated accesses to one row (the aggressor) give off electrical disturbance whose cumu... » read more

HECTOR-V: A Heterogeneous CPU Architecture for a Secure RISC-V Execution Environment


Summary "To ensure secure and trustworthy execution of applications, vendors frequently embed trusted execution environments into their systems. Here, applications are protected from adversaries, including a malicious operating system. TEEs are usually built by integrating protection mechanisms directly into the processor or by using dedicated external secure elements. However, both of these... » read more
