Understanding Tunneling: Hiding Packets In Plain Sight

Tunneling over untrusted networks is a flexible, powerful security tool. We continue our classic Networking 101 series with Charlie Schluting's gentle introduction to how they work, and some easy-to-try examples with SSH.

Quantum Electronics: Tunneling Effect In Strong Laser Field Interaction Under Attack

Physicists have worked on the quantum physics description of the tunnelling effect for 60 years. The group led by Ursula Keller has now for the first time succeeded in measuring time intervals that enable the direct measurement of the tunnelling time of electrons in laser-induced ionisation. No corresponding delay was measured in the experiment: something that astonished many physicists. An established but perhaps over-simplified explanatory model begins to look shaky.

Scripting SSH and SFTP Made Easy With Python

SSH is an indispensable tool that I use every day for file transfers, remote execution of tasks, setting up network port redirection between systems (tunneling), and securely driving a shell on a remote system. While the SSH commandline client on UNIX and Linux systems is how I interact most often with SSH servers on the remote end, there are times when it is helpful to script some action or series of actions rather than performing them interactively.

Sintering of Au Particles Supported on TiO2(110) during CO Oxidation

Sintering of supported metal catalysts is of primary interest in heterogeneous catalysis. The presence of reactant gases, especially oxidants, often accelerates the sintering of supported metal catalysts. Our in situ studies using scanning tunneling microscopy (STM) compare the sintering of Au particles supported on TiO
