摘要： Technologies are provided in embodiments to manage an authentication confirmation score. Embodiments are configured to identify, in absolute session time, a beginning time and an ending time of an interval of an active user session on a client. Embodiments are also configured to determine a first value representing a first subset of a set of prior user sessions, where the prior user sessions of the first subset were active for at least as long as the beginning time. Embodiments can also determine a second value representing a second subset of the set of prior user sessions, where the prior user sessions of the second subset were active for at least as long as the ending time. Embodiments also determine, based on the first and second values, a decay rate for the authentication confidence score of the active user session. In some embodiments, the set is based on context attributes.

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.
摘要翻译：通常，在一个方面，将噪声注入到与将要呈现在显示器上的内容相关联的位图中以产生噪声位图。噪声位图使用电子代码簿（ECB）加密进行加密。所得到的密文不包括来自内容的可识别模式，如ECB加密典型。噪声的注入可以包括修改位图中的至少像素子集的像素值。可以通过使用计数器，已知修改模式或随机数生成器来修改像素值。可以分析位图以确定位图如何被修改以使位图的随机性最大化，同时确保在呈现时视觉上感觉上类似的噪声位图。在块被加密之前，可以将噪声注入到像素块中。

摘要： In accordance with some embodiments, a protected execution environment may be defined for a graphics processing unit. This framework not only protects the workloads from malware running on the graphics processing unit but also protects those workloads from malware running on the central processing unit. In addition, the trust framework may facilitate proof of secure execution by measuring the code and data structures used to execute the workload. If a part of the trusted computing base of this framework or protected execution environment is compromised, that part can be patched remotely and the patching can be proven remotely throughout attestation in some embodiments.
摘要翻译：根据一些实施例，可以为图形处理单元定义受保护的执行环境。该框架不仅保护了图形处理单元上运行的恶意软件的工作负载，还保护了这些工作负载免受中央处理单元上运行的恶意软件。此外，信任框架可以通过测量用于执行工作负载的代码和数据结构来促进安全执行的证明。如果该框架或受保护的执行环境的可信计算基础的一部分受到损害，那么该部分可以被远程修补，并且在一些实施例中可以通过验证远程验证修补。
