Unlike the standard notion of pseudorandom functions (PRF), a non-adaptive PRF is only required to be indistinguishable from a random function in the eyes of a non-adaptive distinguisher (i.e., one that prepares its oracle calls in advance). A recent line of research has studied the possib...
Pseudo-random functions (PRFs) introduced by Goldwasser, Goldreich, and Micali (FOCS 1984), are one of the most important building blocks in cryptography. A PRF family is a family of seeded functions {fs}, with the property that no efficient adversary can tell the difference between getting ...
Pseudorandomness is a central tool in complexity theory and cryptography. A pseudorandom generator (PRG) is a deterministic function G : {0, 1} n →{0, 1} m which stretches a short random seed into a longer output which looks random to any computationally bounded distinguisher. The question...

英文: The sampling is attained by making use of percentiles of distribution function and pseudo-random order, also is applicable to multi-dimensional interval integrals and sampling random variables. 中文: 该方法是由抽样分布的分位点和伪随机序复合构成的,适用于固定区域上多重积分的计算及随机变量的抽样...

As a secure pseudorandom function (a.k.a. keyed hash function), SipHash can also be used as a secure message authentication code (MAC). But SipHash isnot a hashin the sense of general-purpose key-less hash function such as BLAKE3 or SHA-3. SipHash should therefore always be used with...
Key-Homomorphic Pseudorandom Functions from LWE with Small Modulus Sam Kim(B) Stanford University, Stanford, USA skim13@cs.stanford.edu Abstract. Pseudorandom functions (PRFs) are fundamental objects in cryptography that play a central role in symmetric-key cryptography. Although PRFs can be ...
