    Abstract: Architectures and techniques that allow an electronic platform having a Radio Frequency Identification (RFID) tag to transmit platform security status information regardless of the power state of the platform. The RFID tag contains both an external passive RF interface as well as an internal bus interface that may allow components of the host platform to communicate with the RFID tag. The embedded processing agent may provide the ability to detect that a system has come under attack and cause suspicious traffic to be blocked.

    Abstract: Apparatuses and methods for page coloring to associate memory pages with programs are disclosed. In one embodiment, an apparatus includes a paging unit and an interface to access a memory. The paging unit includes translation logic and comparison logic. The translation logic is to translate a first address to a second address. The first address is to be provided by an instruction stored in a first page in the memory. The translation is based on an entry in a data structure, and the entry is to include a base address of a second page in the memory including the second address. The comparison logic is to compare the color of the first page to the color of the second page. The color of the first page is to indicate association of the first page with a first program including the first instruction. The data structure entry is also to include the color of the second page to indicate association of the second page with the first program or a second program.

    Abstract: Method, apparatus, and system for isolating potentially vulnerable nodes of a network. In one embodiment a network is partitioned into subnets of varying levels of security. A client device may be assigned a network access assignment through one of the subnets based on a level of vulnerability assessed for the client device. The level of vulnerability may be determined based on compliance of the client device with available upgrades and/or patches.

    Abstract: Methods and apparatuses associated with sharing cryptographic keys in a network domain. An embedded agent on a network endpoint participates in the distribution of cryptographic keys. In one embodiment the embedded agent receives and stores a shared symmetric key, as do embedded agents on other network endpoints in the same network domain. The embedded agent causes the shared key to be stored in a secure storage not directly accessible by the host. When the host wants to transmit enciphered data, the embedded agent may provide access to cryptographic services. The embedded agent provides isolation of the shared key from parts of the host that are subject to compromise by attack or infection.

    Abstract translation: 与网络域中共享加密密钥相关联的方法和设备。 网络端点上的嵌入式代理参与加密密钥的分发。 在一个实施例中，嵌入式代理接收并存储共享的对称密钥，以及在相同网络域中的其他网络端点上的嵌入代理。 嵌入式代理使共享密钥存储在主机不能直接访问的安全存储器中。 当主机想要传输加密数据时，嵌入式代理可以提供对加密服务的访问。 嵌入式代理提供了通过攻击或感染而受到妥协的主机部分的共享密钥的隔离。
