摘要： Various examples are directed to systems and methods for communications security. For example, a computing device may generate a connection between the computing device and a client device. A first application executing at the computing device may send a first application session key to the client device via the connection. The first application may perform a cryptographic operation on a first message based at least in part on the first application session key to generate a first cryptographic result and send the first cryptographic result to the client device via the connection. The first application may receive a second cryptographic result from the client device via the connection and determine that the second cryptographic result was obtained with the first application session key.

摘要： A data processing system (DPS) uses platform protection technology (PPT) to protect some or all of the code and data belonging to certain software modules. The PPT may include a virtual machine monitor (VMM) to enable an untrusted application and a trusted application to run on top of a single operating system (OS), while preventing the untrusted application from accessing memory used by the trusted application. The VMM may use a first extended page table (EPT) to translate a guest physical address (GPA) into a first host physical address (HPA) for the untrusted application. The VMM may use a second EPT to translate the GPA into a second HPA for the trusted application. The first and second EPTs may map the same GPA to different HPAs. Other embodiments are described and claimed.
摘要翻译：数据处理系统（DPS）使用平台保护技术（PPT）来保护属于某些软件模块的部分或全部代码和数据。 PPT可以包括虚拟机监视器（VMM），以使得不可信应用和可信应用在单个操作系统（OS）之上运行，同时防止不受信任的应用访问可信应用所使用的存储器。 VMM可以使用第一扩展页表（EPT）来将访客物理地址（GPA）转换为不可信应用的第一主机物理地址（HPA）。 VMM可以使用第二EPT将GPA转换为可信应用的第二HPA。第一和第二EPT可以将相同的GPA映射到不同的HPA。描述和要求保护其他实施例。
