Weighted Hamming distance for PUF performance evaluation

WebOct 25, 2024 · Hamming distance is a way of understanding how codes differ. This can then be used to correct errors. TL;DR (Too Long; Didn't Read) Hamming distance refers to the number of points at which two lines of binary code differ, determined by simply adding up the number of spots where two lines of code differ. Webﬂuctuations. To evaluate the reliability of a PUF, the Hamming distance (HD) is calculated between the expected output vector and the actual output. HD is a measure of similarity, which is deﬁned as the number of unidentical bits in the corresponding bit positions. The HD between two n-bit binary strings of x and y is deﬁned as HD(x, y ...

WebThe Hamming distance defines the number of bits that need to change in a binary value in order to produce another value. In this example we can enter a number of binary values: Enter binary values (with a comma between values): Values: 00000,01101,10110,11011 Hamming distance of 01,11,10 gives a Hamming distance of 1. Calc WebFor any two binary strings β and γ such that HD (β, γ) ≤ k, consider r-cut (β) and r-cut (γ) where r ≥ ⌊k/2⌋ + 1. It must be the case that HD (βi, γi) ≤ 1 for at least q = r − ⌊k/2⌋ different values of i. For example, we have binary string of length N = 8 bits. And we would like to find substrings with k = 2.
