A Hundred Attacks in Distributed Systems

Authors: Arash Vaezi, Sara Azarnoush, Parsa Mohammadian
Comments: 37 Pages.

The objective of any security system is the capacity to keep a secret. It is vital to keep the data secret when it is stored as well as when it is sent over a network. Nowadays, many people utilize the internet to access various resources, and several businesses employ a dispersed environment to give services to their users. As a result, a more secure distributed environment is required, in which all transactions and processes can be effectively completed safely. It is critical in a distributed system environment to deliver reliable services to users at any time and from any place. As an example of a distributed system, Blockchain is a unique distributed system that has confronted lots of attacks despite its security mechanism. Security is a top priority in a distributed setting. This paper organizes many attacks that byzantine users may apply to take advantage of the loyal users of a system. A wide range of previous articles dealt considered diverse types of attacks. However, we could not find a well-organized document that helps scientists consider different attacking aspects while designing a new distributed system. A hundred various kinds of most essential attacks are categorized and summarized in this article.

Mathematical Modeling in Delphi

Authors: A. V. Serghienko
Comments: 38 Pages.

The literature on Delphi numbers many manuals. However among them there are few books, oriented to the solution of scientific and technical problems. The work contains the examples of programs in Delphi. Depending on the type of problems it is convenient to use or graphic (usual), or console applications of Delphi. Graphic applications are applicable for the plotting of functions. Console applications are applicable especially, when we needn’t the visualization, and it is necessary to introduce by hand lots of data. One can tell the console applications from the graphic ones with the presence of the next line in the text of program: {$APPTYPE CONSOLE}
