Authenticated hash tables [PDF]
Proceedings of the 15th ACM conference on Computer and communications security, 2008 Hash tables are fundamental data structures that optimally answer membership queries. Suppose a client stores n elements in a hash table that is outsourced at a remote server so that the client can save space or achieve load balancing. Authenticating the hash table functionality, i.e., verifying the correctness of queries answered by the server and ...

A Rolling Hash Algorithm and the Implementation to LZ4 Data Compression
IEEE Access, 2020 LZ77 is a dictionary compression algorithm by replacing the repeating sequence with the addresses of the previous referenced data in the stream. To find out these repetition, the LZ77 encoder maintains a hashing table, which have to frequently calculate ...

Locality-Sensitive Hashing for Information Retrieval System on Multiple GPGPU Devices
Applied Sciences, 2020 It is challenging to build a real-time information retrieval system, especially for systems with high-dimensional big data. To structure big data, many hashing algorithms that map similar data items to the same bucket to advance the search have been ...

Comparison of Hash Table Performance with Open Addressing and Closed Addressing: An Empirical Study [PDF]
International Journal of Networked and Distributed Computing (IJNDC), 2015 In this paper, we conducted empirical experiments to study the performance of hashing with a large set of data and compared the results of different collision approaches. The experiment results leaned more to closed addressing than to open addressing and

Distributed Paged Hash Tables [PDF]
, 2003 In this paper we present the design and implementation of DPH, a storage layer for cluster environments. DPH is a Distributed Data Structure (DDS) based on the distribution of a paged hash table. It combines main memory with file system resources across the cluster in order to implement a distributed dictionary that can be used for the storage of very ...
