I'm a future author and have some questions

You have to assume, that attackers are economically reasonable. This holds true for both, the digital and the real world. If a bank vault is known to contain $100, no sane robber would even attempt to get into it, since his expenses for planning the robbery would exceed the loot. So the real question is: How much is access to your data worth to the adversary? So you should choose your defensive means appropriately to make it economically unfeasible to attack you. I have done the calculations i…

Master-Key in der Cloud?!

Hallo @thoko111! Schön, dass du das kritisch hinterfragst. Lass es mich mal mit einem Beispiel beantworten: Der Trick liegt in der sogenannten Key Derivation Function (KDF). Wir setzen hier auf Scrypt mit einem Cost Factor von 2^15 (ehemals 2^14). Dies ist eine Funktion, die bewusst mathematisch so konstruiert wurde, dass sie eine gewisse Menge CPU-Zyklen und eine bestimmte Menge RAM benötigt. Nehmen wir zunächst einmal an, dass der Angreifer einen single-threaded Offlinebruteforceangriff (d.h…

@Michael

“non-pro users” would be treated differently. That is not the case.

Thanks Michael for pointing this out and it is absolutely true!
