Systems and methods for reducing latency through motion estimation and compensation techniques are disclosed. The systems and methods include a client device that uses transmitted lookup tables from a remote server to match user input to motion vectors, and tag and sum those motion vectors. When a remote server transmits encoded video frames to the client, the client decodes those video frames and applies the summed motion vectors to the decoded frames to estimate motion in those frames. In certain embodiments, the systems and methods generate motion vectors at a server based on predetermined criteria and transmit the generated motion vectors and one or more invalidators to a client, which caches those motion vectors and invalidators.

Scalable hierarchical abnormality localization in cyber-physical systems
A cyber-physical system may have monitoring nodes that generate a series of current monitoring node values over time that represent current operation of the system. A hierarchical abnormality localization computer platform accesses a multi-level hierarchy of elements, and elements in a first level of the hierarchy are associated with elements in at least one lower level of the hierarchy and at least some elements may be associated with monitoring nodes. The computer platform may then determine, based on feature vectors and a decision boundary, an abnormality status for a first element in the highest level of the hierarchy. If the abnormality status indicates an abnormality, the computer platform may determine an abnormality status for elements, associated with the first element, in at least one level of the hierarchy lower than the level of the first element. These determinations may be repeated until an abnormality is localized to a monitoring node. |

Translation of client certificate authentication into authorization graph descriptors
A cloud computing environment receives a request from a client. The request relates to access of an application executing in the cloud computing environment and it encapsulates a certificate. This certificate is then translated into an authorization graph descriptor which, in turn, is used to traverse a certificate authorization graph to identify a match within a certificate repository. In response to the identification of the match, an access token is requested including the authorization graph descriptor. The access token is then encapsulated in the request which is then forwarded to an authentication service which provides access to the application if there is a match of the authorization graph descriptor against pre-defined authorization requirements. Related apparatus, systems, techniques and articles are also described. |

Secure permissioning of access to user accounts, including secure deauthorization of access to user accounts
A permissions management system is disclosed for enabling a user to securely authorize a third-party system to access user account data and initiate transactions related to a user account, without disclosing to the third-party system account credentials. The system enables the user to also securely de-authorize the third-party system. For example, records may be automatically generated that securely store account information, including one or more permissions related to the account and/or the third-party. A token associated with a record may be shared with the third-party system, but neither the record itself, nor the user account credentials, may be shared with the third-party. Accordingly, the third-party may request user account data and/or initiate transactions by providing the token, but does not itself know, e.g., the user account credentials. Further, the user may set various permissions related to the token, and may also revoke the token (e.g., de-authorize the third-party), thus providing increased security to the user's account. |

EZ-pass: an energy performance-efficient power-gating router architecture for scalable on-chip interconnect architecture
With the advent of manycore architecture, on-chip interconnect connects a number of cores, caches, memory modules, accelerators, graphic processing unit (GPU) or chiplets in one system. However, on-chip interconnect architecture consumes a significant portion of total parallel computing chip power. Power-gating is an effective technique to reduce power consumption by powering off the routers, but it suffers from a large wake-up latency to resume the full activity of routers. Recent research aims to improve the wake-up latency penalty by hiding it through early wake-up techniques. However, these techniques do not exploit the full advantage of power-gating due to the early wake-up. Consequently, they do not achieve significant power savings. The present invention provides a new router architecture that remedies the large wake-up latency overheads while providing significant power savings. The invention takes advantage of a simple switch to transmit packets without waking up the router. Additionally, the technique hides the wake-up latency by continuing to provide packet transmission during the wake-up phase. |
