There are many ‘cascade-type’ constructions in symmetric key cryptography. For these, the output of a PRF (or block cipher) is cascaded to next PRF, and this continues until all blocks given message exhausted. In order prove security these constructions, traditionally multi-oracle families, together with query-based hybrid arguments used, but produce longer proofs which cannot be extended quant...

A filter oracle for a clutter consists of finite set V and an which, given any X⊆V, decides in unit time whether X contains member the clutter. Let A2n be algorithm that, C over 2n elements via oracle, is ideal. We prove that worst case, makes at least 2n−1 calls to oracle. Our proof uses theory cuboids.

Comparing the computational power of quantum computers vs classical computers has been extensively studied since the invention of quantum computing. A related question is whether a quantum oracle is more powerful than a classical oracle. In this paper, we examine two topics that give partial answers to this question. We show that we can imitate a polynomial number of columns of a quantum oracle...

The oracle problem is addressed for random testing and testing of randomized software. The presented Statistical Oracle is a Heuristic Oracle using statistical methods, especially statistical tests. The Statistical Oracle is applicable in case there are explicit formulae for the mean, the distribution, and so on, of characteristics computable from the test result. However, the present paper onl...

Definition 1.1. An oracle TM M ? is a Turing machine that an extra tape, called the oracle tape, as well as three special states, a query state qquery and two answer states qyes and qno. It is designed to be used with an oracle (or black box) that decides decides membership in some set of strings. When M ? enters the query state with a string z on its query tape, in the next step, the machine e...

This proposed work aims to provide a powerful Integrated Development Environment (IDE) client for Oracle database server. Using this client tool user does not require more knowledge of oracle database. With the intuitive DB tool GUI increase your code quality and reduce the development process time. By using this client software IDE, users can access and maintain the oracle software in an easy ...
