本书的核心目的是展示如何在分布式编程中增强安全性。现代计算范式通常依赖于分配到若干过程的方法，以利用计算能力。然而，大多数分布式编程的计算机程序员面临着开发可靠的安全分发程序的最根本的挑战。即使在执行非常常见的任务的过程中，作者也认为缺乏愚蠢的证明技术可能导致过程失败。特别指出的是，除了安全性之外，可靠性也是一个持续存在的问题。可靠性是一个问题，因为开发了分布式编程流程，它们应该支持其他流程，并且有一个极端的过程合作来执行常见的任务。即使其他进程失败，这种可靠性保证也是必要的。故障可能从简单的崩溃到某种形式的敌对攻击，使系统的程序支持无用。当这些过程服务器被删除时，就会发生恶意的过程。在本文中，作者Cachin、Guerraoui和Rodrigues(2011)介绍了基本的分布式编程抽象。

目前的抽象和实现的算法需要它们能够承受崩溃和恶意攻击。当作者介绍了有助于更容易理解的内容时，作者使用了一种递增的方法。作者首先介绍了在一个简单的分布式环境中可以使用的基本抽象。其次，作者接着介绍了可以在复杂且更具挑战性的环境中使用的抽象形式。对于那些从第一阶段开始学习这些算法的程序员来说，他们能够更好地遵循推理的思路。抽象概念是从已经使用的基本编程模型和抽象中提取出来的，并且适用于分布式编程环境。各章节都是分段的，以覆盖每一个章节。有一些章节为可靠的广播、共享的记忆、共识、扩展的共识等。

The core purpose of the book is to present how security can be enhanced in distributed programming. Modern computing paradigm usually relies on the approach of distribution to several processes in order to harness computing power. However, most computer programmers for distributed programming face the most fundamental challenge of developing reliable secure distribute programs. Even in the execution of very common tasks, the authors contend that lack of fool proof techniques could result in process failure. In particular it is presented that in addition to security, reliability is an ongoing problem. Reliability is an issue because distributed programming processes are developed such that they should support other processes and there is extreme process cooperation to execute common tasks. This reliability assurance is a necessity even if other processes fail. Failures could be anywhere from a simple crash to some form of an adversarial attack that renders the systems the programs support as useless. Malicious process undertakings happen when such process servers are brought down. It is in this context, that authors Cachin, Guerraoui, and Rodrigues (2011) present an introductory description of fundamental distributed programming abstractions.

The present the abstractions along with the algorithms needed for their implementation which would allow them to withstand crashes and malicious attacks. An incremental approach is made use of by the authors when they present the content which facilitates for easier understanding. The authors firstly present the basic abstractions that could be made use of in a simple distributed environment. Secondly, the authors go on to introduce the form of abstractions that could be made use of in sophisticated and more challenging environments. For programmers who would be learning these algorithms from phase one, they would be able to follow the line of reasoning better. The abstractions are drawn from basic programming models and abstractions already in use and are applied as suited for the distributed programming environment. The chapters are sectioned so as to cover one chapter on each of these abstractions. There are chapters allotted for reliable broadcast, shared memory, consensus, extensions of consensus etc.
