In this paper we present the protection of long lived private key & public key using cryptographic schemes is one of the most important issues for information security. Any cryptographic scheme that reveals private key and public key will soon its security absolutely disintegrates. Public key are used in two different based, i.e. RSA and elliptic curve cryptography both are modular based arithm...
Meta-heuristics have already received considerable attention in various fields of engineering optimization problems. Each of them employes some key features best suited for a specific class of problems due to its type of search space and constraints. The present work develops a Pseudo-random Directional Search, PDS, for adaptive combination of such heuristic operators. It utilizes a short term...

We introduce the notion of key stretching, a mechanism to convert short s-bit keys into longer keys, such that the complexity required to brute-force search a s+ t-bit keyspace is the same as the time required to brute-force search a s-bit key stretched by t bits.
A buyer can either buy a good at local monopolist or search for it in the market. The more intensely searches, likely he will find market; if his fails, still from monopolist. We show that with higher willingness to pay searches (weakly) intensely. This skews distribution of types buying toward lower valuations and exerts pressure on reduce price. Despite this effect, offering monopoly price re...
Introduction: Public-private partnership can help governments deal with resource constraints in their health sectors. The aim of this study was to investigate the effects of different models of public-private partnership on hospital mid-indicators and identify factors affecting its successful implementation. Methods: This critical review was conducted from 2000 to 2017. Databases, such as Goog...
