A set of hash functions ℋ = {h : U →{0,1,2,...,m−1}} is called a universal family if for any two keys x,y ∈ U,x ̸= y the probability of collision Pr[h(x) = h(y)] ≤ 1/m 我的理解是生成一个随机h函数集H,在运行hash function的时候,调用其中的随机h,这样可以保...
A Universal One-Way Hash Function (UOWHF) is a class of hash functions indexed by a public parameter (called a key ), for which finding a second preimage is hard. The main idea is that first the challenge input is selected, and subsequently the function instance (or parameter) is chosen...

We show that every almost universal hash function also has the storage enforcement property. Almost universal hash functions have found numerous applications and we show that this new storage enforcement property allows the application of almost universal hash functions in a wide range of remote ...
The wireless device obtains the input message. The wireless device generates a keystream. The wireless device computes a message authentication code using the keystream and a universal hash function. The universal hash function is computed using carryless multiplication....
computation in which a cryptographic hash function is modeled as a black box, access to which is allowed only through explicit oracle queries. While the Random Oracle model is a useful heuristic, it does not rule out all possible attacks: a scheme proven secure in this model might still be ...

MACs may be built around a universal hash function (NH) which was explored in the construction of UMAC. In this paper, we use a variation on NH called WH. WH reaches optimally in the sense that it is universal with half the hash length of NH and it achieves perfect serialization in ...
