Collaborate Disseminate
I have a cipher text, that was created using One-Time-Pad, but the idea is that it was encrypted badly. The message, a section of a book, was encrypted using a pad 256B long repeated many times over (like Vigenere).
Any ideas how to break … Continue reading How to break poorly implemented One-Time-Pad
My train of thought went, OTP is very secure if key is unknown because I am guessing the original message. AES on the other hand tells me I gave it the wrong key, and if I did I can just switch using another key without having to worry abo… Continue reading Is AES worse than OTP, if so is there proofs [migrated]
Is there any ways to increase the security of One Time Pad algorithm?
We required to make a write up on how to increase the security of classical cryptography algorithm. In this case, we are choosing one-time pad.

I am confused regarding this: I am working on a project but I want to use a one-time pad and want to launch a meet-in-the-middle attack on my new scheme for data security. As block ciphers are vulnerable to meet-in-the-middle attack, I am … Continue reading Can a one-time pad prevent a meet-in-the-middle attack?
There is a risk of confusion with the abbreviation OTP.
OTP == One-Time Pad
OTP == One Time Password

I am reading "Serious cryptography" and he wrote the following:
Informational security is based not on how hard it is to break a cipher,
but whether it’s conceivable to break it at all. A cipher is informationally
secure only if… Continue reading Why is one-time pad informationally secure?
I’m part of a team of students from the Vienna University of Economics who have the task to find applicable fields for a new technology.
The technology itself is provided by an external partner, so I do not possess a lot of technical knowl… Continue reading How could unbreakable encryption be used? [closed]
For many years now I have been using PGP with a number of recipients, also at times with the private key generated in a smartcard. When I think of it, almost every one of those people I see in person now and then. So all this carry-on abou… Continue reading strongest email encryption where keys can be exchanged in person
It’s a concern for Europeans as it is for people elsewhere in the world: there have been suggestions among governments to either outlaw, curtail, or backdoor strong end-to-end encryption. There …read more Continue reading Simple Encryption You Can Do On Paper
This question might be uncannily similiar to this one posted over 6 years ago, but the structure is completely different.
It’s written nearly everywhere that OTPs are incapable of sustaining more than their length of data – but I have yet … Continue reading Is it possible to attack a one-time pad encrypting only slightly more than its length?
