Datalair is a practical plausible deniability system built based on a new write-only ORAM. It reduces the complexity of the state of the art existing write-only ORAM by a factor of O(logN). When compared with existing approaches, DataLair is two orders of magnitude faster (and as efficient as the underlying raw storage) for public data accesses, and 2-5 times faster for hidden data accesses.
PD-DM is a new efficient device mapper with strong plausible deniability against multi-snapshot adversaries. It preserves locality and increases performance by ensuring most of its underlying writes are sequential. In a typical setup, throughputs are one order of magnitude (10-100x) faster than existing approaches.
This project aims to detect the existence and location of specific instances of target data structure types in a VM by observing memory accesses and training for targetspecific timing-based signatures. We deploy the detection mechanisms to defeat kernel rootkits that "hide" their associated processes from existing snapshot-based detection methods. We introduce multiple signature variants and evaluate them for different kernel versions.
Smartphone Datacenter looks insight into the power-performance tradeoff at scale for ARM and x86 architectures by quantifying the cost/performance ratio precisely enough to allow for a broader conclusion about the feasibility of deploying an ARM datacenter in next few years.
Green DIMM is a system that aims at energy efficient memory management in OS.
HIFS for flash is a file system designed for flash storage devices with a good balance between the history independent security and device life time.
