In cryptography, a distribution ensemble or probability ensemble is a family of distributions or random variables X = { X i } i ∈ I {\displaystyle X=\{X_{i}\}_{i\in I}} where I {\displaystyle I} is a (countable) index set, and each X i {\displaystyle X_{i}} is a random variable, or probability distribution. Often I = N {\displaystyle I=\mathbb {N} } and it is required that each X n {\displaystyle X_{n}} have a certain property for n sufficiently large.
