Information Leakage from Opti al Emanations

Countermeasure Technique for Preventing Information Leakage Caused by Unintentional PC Display Emanations

A working personal computer (PC) and/or a PC display monitor usually produce unintentional electromagnetic fields. It has been known that the information from a video display unit could be reconstructed by intercepting such emissions at a distance. Proper measures are needed to prevent information leakage against such eavesdropping, which are often collectively called “TEMPEST”. We have studied...

TruSense: Information Leakage from TrustZone

With the emergence of Internet of Things, mobile devices are generating more network traffic than ever. TrustZone is a hardware-enabled trusted execution environment for ARM processors. While TrustZone is effective in providing the muchneeded memory isolation, we observe that it is possible to derive secret information from secure world using the cache contention, due to its high-performance ca...

Increased Information Leakage from Text

The enormous data sharing and data availability on the Internet provides opportunities for new services tailored to extract, search, aggregate, and mine data in meaningful ways, At the same time, it poses challenges with regards to data privacy. This paper offers insight into this problem, focusing on current relevant research and potential areas of synergy between the information retrieval com...

Information leakage from logically equivalent frames q

Framing effects are said to occur when equivalent frames lead to different choices. However, the equivalence in question has been incompletely conceptualized. In a new normative analysis of framing effects, we complete the conceptualization by introducing the notion of information equivalence. Information equivalence obtains when no choice-relevant inferences can be drawn from the speaker s cho...
