Types of Hashing in DBMS There are typically two types of hashing techniques in DBMS: 1. Static Hashing 2. Dynamic Hashing 1. Static Hashing In the case of static hashing, the data set formed and the bucket address is the same. This means that if we try to generate the address for USE...
Static Hashing is one amongst the various other hashing techniques used for mapping the unordered data placements into a sorted format, and also by providing the proper identification of the memory addresses to each value in the database. Unlike other Hashing, the Static Hashing process can be ap...
Recently, a number of techniques for dynamic hashing have appeared. In this paper, we present a solution to allow for concurrency in one of these dynamic hashing data structures, namely extendible hashfiles. The solution is based on locking protocols and minor modifications in the data structure....
To be more precise, the circuit topology of the function is revealed, but this information leakage can be removed or mitigated by using techniques such as universal circuit [Val76, KS08b,LMS16,KS16] or circuit branch overlay [KKW16]. In practical scenarios, evaluated functions are to be ...

Annual International Conference on the Theory and Applications of Cryptographic Techniques 2821 Accesses 4 Citations Abstract We introduce Free Hash, a new approach to generating Garbled Circuit (GC) hash at no extra cost during GC generation. This is in contrast with state-of-the-art approach...
A Relational Database Management System (RDBMS) is a database management system (DBMS) which uses relational techniques for storing and retrieving data. RDBMS software using a Structured Query Language (SQL) interface is well known in the art. The SQL interface has evolved into a standard ...
Optimal search in main memory databases requires at most one key comparisonto locate a record. Extendible hashing becomes impractical when it is adapted to yield optimal search in main memory databases because of its large directory size. Multi-directory hashing techniques can provide significantly ...

Some common strategies utilized by the prior art are open addressing, closed addressing and cuckoo addressing but most of these techniques provide additional challenges. For example, in a closed addressing strategy, a method also known as separate chaining, each slot is independent and has some sort...
