Some Thoughts on Time-Memory-Data Tradeoffs

In this paper we show that Time-Memory tradeoff by Hellman may be extended to Time-Memory-Key tradeoff thus allowing attacks much faster than exhaustive search for ciphers for which typically it is stated that no such attack exists. For example, as a result AES with 128-bit key has only 85-bit security if 2 encryptions of an arbitrary fixed text under different keys are available to the attacke...

JUDGMENTS OVER TIME The Interplay of Thoughts , Feelings , and Behaviors

Real-time assessment of suicidal thoughts and behaviors

One of the greatest challenges to understanding, predicting, and preventing suicide is that we have never had the ability to observe and intervene upon them as they unfold in real-time. Recently developed real-time monitoring methods are creating new opportunities for scientific and clinical advances. For instance, recent real-time monitoring studies of suicidal thoughts show that they typicall...

The whirligig of time: Some thoughts on Staddon and Higa.

Hamlet’s lament may echo many of those researchers who have taken up the task of understanding the nature of time itself. Time as an entity of scientific concern has largely been the province of physics, where time stands as one of the four fundamental dimensions along with length, mass, and charge, whose combinations define virtually all other physical variables. Yet, time remains the most mys...
