Despite that font can be decompiled, is it practical to encrypt text with sophisticatedly designed font? ( font and ciphertext are both provided )
This font is crea… Continue reading Is it practicable to encrypt text with sophisticatedly designed font?
If you have more than a few bank cards, door-entry keycodes, or other small numeric passwords to remember, it eventually gets to be a hassle. The worst, for me, is a bank card for a business account that I use once in a blue moon. I probably used it eight times in five years, and then they gave me a new card with a new PIN. Sigh.
How would a normal person cope with a proliferation of PINs? They’d write down the numbers on a piece of paper and keep it in their wallet. We all know how that ends, …read more
I read that because the Soviets weren’t careful enough with their one-time-pads, by unintentionally reusing some, they allowed the West to break their encrypted communication.
Does this mean that when using such a technique … Continue reading Using one-time-pads require list of used ones?
This is the question that I am trying to create a voting system for, and I wanted to submit it for belittlement.
It’s a remote voting system, and our voters need to show evidence they supported the basilisk after the electio… Continue reading Is this voting system secure in an information theory sense?
Can I decode a message that was encrypted with a one-time pad if I have the key used to encrypt it? If so, how?
For a lot of web services offering two factor authentication, after setting up the system, you are given a short list of backup codes (one-time pads) that are around 7-10 characters long. These are meant to be used in cases where you do no… Continue reading Best practices for usefully storing two factor authentication backup codes?
I have read that in order for a one time pad to be truly secure, the pad itself must be random data. Given the practical difficulty of sharing a secure random pad, I was wondering what would be the problems with using the va… Continue reading How to cryptoanalyze a one time pad that uses a plain text document as the pad?
I understand that one of the requirements (and a major drawback) of OTP is that the key has to be as long as the message is.
What happens if I have a key that is shorter? The message would only get encrypted partially, right?
For example… Continue reading How to use one time pad if the key is shorter than the plaintext?
We all know the two most important problems related to a “one-time-pad”:
The one-time-pad needs to be truly random (which I think is logic, as pseudo random generators are quick but predictable).
The practicability of being able to tran… Continue reading Is using a numbers station to transmit a one-time-pad as key actually insecure?
