Achieving sub-block non-malleability
I have a noisy one-way communication channel where data is sent as a series of words of width n bits.
Assume n is a constant roughly in the range of 16...48.
I don't want bit errors in one word to ...

After ZK-shuffle, how can we let people who got the same number card know each other without letting anyone else know?
In mental poker, we can use ZK-shuffle to deal cards to the players such that the cards are kept private to each player (https://hackmd.io/@nmohnblatt/SJKJfVqzq). Suppose we deal exactly one card to ...

Are there on-line ways to use a block cipher to generate unique $n$ bits that guarantee collision-freeness for $2^n$ times?
$n$ is a run-time variable chosen each time the user runs the implementation.
One way I can think is to use any block cipher, say AES, as a seeded CSPRNG to randomly shuffle list of numbers $0, 1, \...

Multiple attributes under shuffled differential privacy
Notation: eps_c (epsilon central), eps_l (epsilon local), n (number of users), d (number of attributes). A single attribute A_i may have |A_i|=r different values for i in [1,d].
Let's suppose each ...
