    Abstract: In one embodiment, a device containing sensitive information may be placed in a data security mode. In such a data security mode, certain activities may trigger the partial or full erasure of the sensitive date before the data can be retrieved by an unauthorized user. In one embodiment, the data security mode may be a park mode in which unauthorized physical movement of the device triggers the partial or full erasure of the sensitive data stored in a nonvolatile memory before the data can be retrieved by an unauthorized user. In another aspect of the present description, the earths magnetic field may be used to detect movement of a device in the park mode, and may be used to power the erasure of sensitive data as the device is moved relative to the earths magnetic field. Other aspects are described herein.

    Abstract: An integrated-circuit device (1) comprises a processor (7), memory (13) for storing executable code, and memory protection logic (9). The memory protection logic (9) is configured to: determine the state of a read protection flag for a protected region of the memory (13);detect a memory read request by the processor (7); determine whether the read request is for an address in the protected region of the memory (13); determine whether the processor (7) issued the read request while executing code stored in the protected region of the memory (13); and deny read requests for addresses in the protected region if the read protection flag for the protected region is set, unless at least one of one or more access conditions is met, wherein one of the access conditions is that the processor (7) issued the read requests while executing code stored in the protected region.

    Abstract: In one embodiment, the present invention includes a method for determining whether an address map of a system includes support for a read only region of system memory, and if so configuring the region and storing protected data in the region. This data, at least some of which can be readable in both trusted and untrusted modes, can be accessed from the read only region during execution of untrusted code. Other embodiments are described and claimed.

    Abstract: A method of securing network authentication information at a data processing device includes determining a boot source from which to boot the device and comparing the boot source to an expected source. If the boot source is not the expected source, access to the network authentication information is inhibited, such as by disabling access to the portion of memory that stores the authentication information. Further, if the boot source is the expected source, boot code authentication information is retrieved from memory and verified during the boot sequence. If the device authentication information is not authenticated, access to the network authentication information is inhibited. Accordingly, access to the network authentication information is allowed only if the data processing device is booted from an expected source, and only if the boot code is authenticated, thereby reducing the likelihood of unauthorized access to the network authentication information.

    Abstract translation: 一种在数据处理设备处确保网络认证信息的方法包括确定从哪个引导设备并将引导源与预期源进行比较的引导源。 如果引导源不是预期的源,则禁止对网络认证信息的访问,例如通过禁止访问存储认证信息的存储器部分。 此外,如果引导源是预期源,则从存储器检索引导代码认证信息,并在引导顺序期间进行验证。 如果设备认证信息未认证,则禁止接入网络认证信息。 因此,仅当数据处理装置从预期的源启动,并且只有在引导代码被认证时才允许对网络认证信息的访问,从而降低未授权访问网络认证信息的可能性。

    Abstract: An architecture is presented that facilitates integrated security capabilities. A memory module (100, 200, 400) is provided that comprises non-volatile memory (102, 202, 402) that stores security software and a security processor (104, 204, 300, 404) that accesses the security software from the nonvolatile memory (102, 202, 402) and performs security functions based on the security software stored. Further, a host processor (206, 406) located outside of the memory module (100, 200, 400) arbitrates with the security processor (104, 204, 300, 404) for access to the non-volatile memory (102, 202, 402). The memory module (100, 200, 400) in communication with the host processor (206, 406) establishes a heightened level of security that can be utilized in authentication services and secure channel communications.

The memory (46) is accessible through the test interface (34). In response to resetting this microcontroller (30), a counter is started and the test interface (34) is initially set to a disabled state while an initiation program is executed. The test interface (34) is changed to an enabled state - such that access to the embedded memory (46) is permitted through it - when the counter reaches a predefined value unless the microcontroller (30) executes programming code before the predefined value is reached to provide the disabled state during subsequent microcontroller (30) operation.
