Computer and communication platform security and content protection

在计算和通信设备的上下文中，平台是膝上型计算机、个人计算机（PC）、服务器、移动的和智能电话、个人数字助理（PDA）等。这些是硬件设备，通常配备有一个或多个处理器、多种类型的存储器和输入-输出接口。操作系统和应用程序在这些平台上执行以提供各种形式的计算和/或通信能力。当今计算机和通信平台处理或存储的信息或数据的使用和价值不断增加，使后者成为许多安全漏洞的中心。在网络环境中，受感染的平台可以快速影响整个网络中的设备和系统，或者通过后门受损的平台可以被攻击者用来挖掘机密信息或对连接到网络的其他平台进行午餐攻击。现有的解决方案，如防火墙和设备上的数据加密软件，通常保护数据，只要设备本身不受损害，但做得很少，以确保平台的完整性。为此，我们建议通过共同考虑平台的完整性以及对平台处理或存储的数据的保护来进行研究。我们的工作将包括开发高效和统一的加密引擎，制定底层计算的算法，以及调查哈希函数，这些都是平台完整性和内容保护的关键。

In the context of computing and communication devices, platforms are laptops, personal computers (PCs), servers, mobile and smart phones, personal digital assistants (PDAs), etc. These are hardware devices, commonly equipped with one or more processors, multiple types of memories, and input-out interfaces. Operating systems and application programs are executed on these platforms to provide computing and/or communication capabilities in various forms. The increasing use and value of the information or data processed by or stored into today's computer and communication platforms has put the latter at the center of many security breaches. In a networked environment, an infected platform can quickly impact devices and systems across the network or a platform compromised through a back-door can be used by an attacker to mine for confidential information or lunch attacks on other platforms connected to the network. Existing solutions such as firewalls and on-device data encryption software typically protect the data as long as the device itself is not compromised, but do little to ensure the integrity of the platform. To this end, we propose to conduct research by jointly considering the integrity of platforms and the protection of data processed by or stored into them. Our work will include the development of efficient and unified crypto-engines, formulation of algorithms for underlying computations, and investigation of hash functions which are all crucial for a platform's integrity and its content protection.
