Social Signals: The Secret Language of Mice

Animals are known to produce substances that modulate social and sexual behavior of conspecifics, but the mechanistic details underlying these phenomena have been elusive. A recent paper identifies a male-specific compound in mouse urine that activates olfactory bulb neurons and mediates behavioral attraction.

Secret Key Agreement by Soft-Decision of Signals in Gaussian Maurer's Model

SUMMARY We consider the problem of secret key agreement in Gaussian Maurer's Model. In Gaussian Maurer's model, legitimate receivers, Alice and Bob, and a wire-tapper, Eve, receive signals randomly generated by a satellite through three independent memoryless Gaussian channels respectively. Then Al-ice and Bob generate a common secret key from their received signals. In this model, we propose a...

My Traces Learn What You Did in the Dark: Recovering Secret Signals Without Key Guesses

In side channel attack (SCA) studies, it is widely believed that unprotected implementations leak information about the intermediate states of the internal cryptographic process. However, directly recovering the intermediate states is not common practice in today’s SCA study. Instead, most SCAs exploit the leakages in a “guess-anddetermine” way, where they take a partial key guess, compute the ...

Secret Sharing

This document provides the basic concept of Secret Sharing technique in practice. Main overview of some current secret sharing schemes are discussed according to the papers, provided during the course. Future scope and possibilities of secret sharing schemes are also introduced.
