    摘要: Systems and methods for secure delivery of output surface bitmaps to a display engine. An example processing system comprises: an architecturally protected memory; and a processing core communicatively coupled to the architecturally protected memory, the processing core comprising a processing logic configured to implement an architecturally-protected execution environment by performing at least one of: executing instructions residing in the architecturally protected memory and preventing an unauthorized access to the architecturally protected memory; wherein the processing logic is further configured to provide a secure video output path by generating an output surface bitmap encrypted with a first encryption key and storing an encrypted first encryption key in an external memory, wherein the encrypted first encryption key is produced by encrypting the first encryption key with a second encryption key.

    摘要: A system is provided to determine whether to re-authenticate a user based on identification parameter measurements of low power sensors. According to an embodiment of the invention, a system may include a processor that includes analysis logic to determine whether to re-authenticate the user based on parameter values received from at least one of one or more agents. The system may also include authentication logic to re-authenticate the user that includes a confirmation of whether the user is authenticated based on input received from one or more authentication sensors. Other embodiments are described and claimed.

    摘要: In general, in one aspect, noise is injected into a bitmap associated with content to be presented on a display to create a noisy bitmap. The noisy bitmap is encrypted using electronic code book (ECB) encryption. The resulting ciphertext does not include recognizable patterns from the content as is typical with ECB encryption. The injection of noise may include modifying pixel values for at least a subset of pixels in the bitmap. The pixel values may be modified by using a counter, a known modification pattern, or a random number generator. The bitmap may be analyzed to determine how the bitmap can be modified to maximize the randomness of the bitmap while ensuring that the noisy bitmap is visually perceptually similar when presented. The noise may be injected into a block of pixels prior to the block being encrypted.

    摘要: A pivoting hub nut, or hub clamp, for manually securing an object to a rotatable shaft provides a first hub defining a first radial slot and a second hub pivotally attached to the first hub defining a second radial slot. A first handle extends from the first hub, and a second handle extends from the second hub. A latch is disposed on the clamp for selectively locking the clamp in a closed position. An axial bore is defined along the centerline, or hub axis of rotation, of the clamp. The clamp includes a threaded region facing the axial bore for engaging corresponding threads on the shaft. Upon installation of the clamp onto the shaft, the clamp can be rotated relative to the shaft in a closed position for adjusting the longitudinal, or axial, placement of the clamp on the shaft, and the clamp can be tightened against a wheel rim or other object for securing the object on the shaft.
