Researchers probe security through obscurity

Shannon sought security against the attacker with unlimited computational powers: if an information source conveys some information, then Shannon's attacker will surely extract that information. Diffie and Hellman refined Shannon's attacker model by ...

Probe-response attacks are a new threat for collaborative intrusion detection systems. A probe is an attack which is deliberately crafted so that its target detects and reports it with a recognizable "fingerprint" in the report. The attacker then uses ...

While a large body of research on image-based authentication has focused on memorability, comparatively less attention has been paid to the new security challenges these schemes may introduce. Because images can convey more information than text, image-...
