The 19-inch rack format with rack-units of 1.75 inches (44.45 mm) was established as a standard by AT&T around 1922 in order to reduce the space required for repeater and termination equipment in a telephone company central office. The earliest repeaters from 1914 were installed in ad hoc fashion on shelves, in wooden boxes and cabinets. Once serial production started, they were built into custom-made racks, one per repeater. But in light of the rapid growth of the toll network, the engineering department of AT&T undertook a systematic redesign, resulting in a family of modular factory-assembled panels all "designed to mount on vertical supports spaced 191⁄2 inches between centers. The height of the different panels will vary, ... but ... in all cases to be a whole multiple of 13⁄4 inches".

Some authentication means are more secure than others: using a hardware device designed to store a private key without making it possible to ever extract it is more secure than storing the private key in a file. Unfortunately the most secure ones are also more painful to use. Users who have their keys on a device need to carry the device with them, need to type their PIN code every time they initiate a SSH session, etc. This makes it quite difficult to advocate ways more secure than passwords and files for use cases where the security of the access is not the priority.

So the question is: is it possible to store the authentication material more securely than in a file (which can be stolen by some malware), without changing the user experience?

And the answer is: yes, using a TPM!

Heute spielen wir wieder Bäumchen wechsel Dich und Tim und Khaleesi führen durch die Sendung. Dabei wird unsere Nerd Cred auf eine harte Probe gestellt und wir prüfen unsere Affinität zu Star Trek, Star Wars, Herr der Ringe und Rollenspielen. Dazu einige gute Nachrichten rund um die Chatkontrolle und die (erfolgreichen) Klagen der Gesellschaft für Freiheitsrechte, der wöchentliche Musk-Rant und Berichte über depressive Suchmaschinen.

Das Gesundheitsministerium hat seine Pläne für die elektronische Patientenakte vorgestellt und am besten soll jetzt alles ganz schnell gehen, ohne viel Gezeter um Datenschutz. Aber wir tun gut daran, Gesundheitssysteme nicht aus Sicht der Mehrheit zu denken, sondern aus Sicht derer, die von solchen Systemen diskriminiert werden könnten, schreibt unsere Kolumnistin.
