compute the distance from q to each point in P, and report the point with the minimum distance. This linear scan approach has query time of Θ(dn). This is tolerable for small data sets, but is too inefficient for large ones. The “holy grail” of the research in the area is to ...

Algorithm design and analysisDatabasesContextThis research aims to examine the effectiveness and efficiency of fuzzing hashing algorithm in the identification of similarities in Malware Analysis. More precisely, it will present the benefit of using fuzzy hashing algorithms, such as ssdeep, sdhash, mvHash...
Sort through all the files in Dir A: a. If the hash value of a file matches a hash value in Pool X, do nothing and go to the next file. b. If the hash value of a file doesn’t match a hash value in Pool X, copy the file to Dir B before moving to the next file. Validat...
4.2.2 Categories of hashing methods The methods to compute hashing functions can be roughly divided into two categories, i.e., data-independent and data-dependent. Data-independent methods usually design generalized hashing functions that can compact any given data set into binary codes. Locality-Se...
But there's another clever technique in the attacker's arsenal: rainbow tables. While hash tables offer instant lookups at the cost of massive storage requirements, rainbow tables take a more sophisticated approach. They use chains of hashes and special reduction functions to compress what would ...

Hash function.The central part of the hashing process is the hash function. This function takes the input data and applies a series of mathematical operations to it, resulting in a fixed-length string of characters. The hash function ensures that even a small change in the input data produces...
in the design of hash functions39,40,41,42,43,44,45,46, they have some inherent disadvantages, such as insufficient nonlinear dynamics, aperiodic windows, and severe chaos degradation. To address these issues, researchers have developed higher-dimensional chaotic systems. For instance, Todorova et...
