所以left hash lemma就提供了一个privacy amplification的方法,即便攻击者知道了这t个bit,User依然可以产生一个长度约为n-t bit的新的key,而保证攻击者对这个新key一无所知。也就是说,left hash lemma实现了这样一个功能,从一个平均分布的随机变量X中提取了H∞(X)个bit,使得了解部分X信息的攻击者对提取出来的...

The famous Leftover Hash Lemma (LHL) states that (almost) universal hash functions are good randomness extractors. Despite its numerous applications, LHL-based extractors suffer from the following two drawbacks: Large Entropy Loss: to extract v bits from distribution X of min-entropy m which are...

The famous Leftover Hash Lemma (LHL) states that (almost) universal hash functions are good randomness extractors. Despite its numerous applications, LHL-based extractors suffer from the following two limitations:Quite surprisingly, we show that both limitations of the LHL — large entropy loss and...
The Leftover Hash Lemma states that the output of a two-universal hash function applied to an input with sufficiently high entropy is almost uniformly random. In its standard formulation, the lemma refers to a notion of randomness that is (usually implicitly) defined with respect to classical si...
