安全协处理器通过提供安全岛来实现安全的分布式应用程序，应用程序可以在其中执行和记录状态，不受攻击者的直接物理访问的观察和干扰。但是，为了使这些协处理器有效工作，此类应用程序的参与者必须能够验证他们正在与真实、未篡改的设备上的真实程序进行交互。此外，支持通用计算并将作为商业产品制造和分发的安全协处理器必须提供这些核心保护区和身份验证特性，同时还要应对许多其他挑战，包括： Ø 应用程序、操作系统、底层安全管理都可能来自不同的、相互怀疑的参与者; Ø 配置和维护必须在恶劣的环境中进行，同时尽量减少对操作的干扰； Ø 设备必须能够从复杂软件中不可避免出现的漏洞中恢复； Ø 物理安全性规定设备本身永远不能被打开和检查； Ø 不断发展的加密要求要求硬件加速器由可重新加载的卡上软件支持 本文总结了我们为解决这些问题而开发的硬件、软件和密码体系结构。

This is a book about developing the software and hardware you never think about. We're talking about the nitty-gritty behind the buttons on your microwave, inside your thermostat, inside the keyboard used to type this description, and even running the monitor on which you are reading it now. Such stuff is termed embedded systems, and this book shows how to design and develop embedded systems at a professional level. Because yes, many people quietly make a successful career doing just that. Building embedded systems can be both fun and intimidating. Putting together an embedded system requires skill sets from multiple engineering disciplines, from software and hardware in particular. Building Embedded Systems is a book about helping you do things in the right way from the beginning of your first project: Programmers who know software will learn what they need to know about hardware. Engineers with hardware knowledge likewise will learn about the software side. Whatever your background is, Building Embedded Systems is the perfect book to fill in any knowledge gaps and get you started in a career programming for everyday devices. Author Changyi Gu brings more than fifteen years of experience in working his way up the ladder in the field of embedded systems. He brings knowledge of numerous approaches to embedded systems design, including the System on Programmable Chips (SOPC) approach that is currently growing to dominate the field. His knowledge and experience make Building Embedded Systems an excellent book for anyone wanting to enter the field, or even just to do some embedded programming as a side project. What You Will Learn Program embedded systems at the hardware level Learn current industry practices in firmware development Develop practical knowledge of embedded hardware options Create tight integration between software and hardware Practice a work flow leading to successful outcomes Build from transistor level to the system level Make sound choices between performance and cost Who This Book Is For Building Embedded Systems: Programmable Hardware is for embedded-system engineers and intermediate electronics enthusiasts who are seeking tighter integration between software and hardware. Those who favor the System on a Programmable Chip (SOPC) approach will in particular benefit from this book. Students in both Electrical Engineering and Computer Science can also benefit from this book and the real-life industry practice it provides.

BAC0 BAC0是一个Python 3（3.5及更高版本）脚本应用程序，它使用处理IP网络上的BACnet消息。 该库带出简单的命令来浏览BACnet网络，从BACnet设备读取属性或对其进行写入。 Python是一种简单易学的语言，并且是用于数据处理的非常强大的工具。 与BACnet耦合后，它成为测试设备与控制器交互作用的好工具。 BAC0的名称来自BACnet / IP通信使用的默认IP端口，即端口47808。以十六进制表示，其写为0xBAC0。 包含网络功能 BAC0包含一个本地网页，该网页将帮助用户提供有关脚本看到的网络的基本信息，并为历史趋势提供一个简单的界面。 Flask用于呈现网页，还提供了Bokeh服务器为用户提供实时趋势。 DDC控件的测试驱动开发（TDD） BAC0专为楼宇自动化系统（BAS）编程人员设计。 在该领域中使用的控制器通常称为DDC控制器（直接数
