We conclude by giving a sufficient condition on the encryption algorithm that guarantees the construction of secure MACs, even when combined with a dependent hash family.doi:10.1007/978-3-319-06734-6_27Basel AlomairSpringer International PublishingB.

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...
The strongest well-known measure for the quality of a universal hash-function family H is its being ε-strongly universal, which measures, for randomly chosen h∈H, one's inability to guess h(m′) even if h(m) is known for some m≠m′. We give example applications in which this meas...

The power of primes: security of authentication based on a universal hash-function family Message authentication codes (MACs) based on universal hash-function families are becoming increasingly popular due to their fast implementation. In this p... B Alomair,A Clark,R Poovendran - 《Journal of ...
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....

This work proposes the XHX family of tweakable block ciphers from a classical block cipher and a family of universal hash functions, which generalizes the constructions by Wang et al. First, we detail the generic XHX construction with three independently keyed calls to the hash function. Second,...
