Abstract: Systems and methods for improved distributed symmetric cryptography are disclosed. A client computer may communicate with a number of cryptographic devices in order to encrypt or decrypt data. Each cryptographic device may possess a secret share and a verification share, which may be used in the process of encrypting or decrypting data. The client computer may generate a commitment and transmit the commitment to the cryptographic devices. Each cryptographic device may generate a partial computation based on the commitment and their respective secret share, and likewise generate a partial signature based on the commitment and their respective verification share. The partial computations and partial signatures may be transmitted to the client computer. The client computer may use the partial computations and partial signatures to generate a cryptographic key and verification signature respectively. The client computer may use the cryptographic key to encrypt or decrypt a message.

Abstract: According to some embodiments, an integration system may include a source data store that contains a plurality of workloads (e.g., data packets). A processing platform may retrieve a workload from the source data store via first unikernel-based workload processing. The processing platform may then process the workload (e.g., filtering or dropping) to generate an output result and arrange for the output result to be provided to a sink destination via second unikernel-based workload processing (e.g., associated with a Linux event loop model of input output multiplexing). In some embodiments, the processing platform initially evaluates the workload in the source data store to determine if the workload meets a predetermined condition. If the workload does not meet the predetermined condition, the retrieving and arranging may be performed via container-based workload processing instead of unikernel-based workload processing.

The method can include receiving, via a user device of a user through a network, an add-to-cart command associated with an anchor item in a session by the user. The method further can include determining, in real-time after receiving the add-to-cart command, a recommendation for one or more complementary items based at least in part on: (a) the anchor item; and (b) a user profile of the user. The method also can include determining, in real-time after determining the recommendation, a recommendation confidence for the recommendation based at least in part on one or more of: (a) the user profile; (b) the anchor item; (c) the one or more complementary items; or (d) one or more feedbacks from the user associated with one or more prior recommendations in the session.

Abstract: Techniques for maintaining isolation and segregation for network paths through multi-cloud fabrics using VRF technologies. The techniques include running virtual routers in a cloud network that connect the cloud network to an on-premises network using a network overlay that preserves VRF information in data packets. Further, the virtual routers connect to individual gateways in the cloud network using tunnels, and each individual gateway is connected to multiple VPCs without overlapping subnets. The virtual routers may assign a sink VRF to each gateway connection that can be used to perform source-IP based VRF selection by mapping source IP addresses in each tunnel connection to appropriate VRFs for the source IP addresses. In this way, virtual routers may use sink VRFs to translate into the VRF information for data packets from the VPCs via source-IP based lookup, and use the corresponding VRF route table to determine next hops for data packets.

Abstract: Example methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to implement contextual key management for data encryption are disclosed. Example apparatus disclosed are to determine whether a key mapping is associated with a combination of two or more context rules defined for a set of context values associated with input data to be encrypted. Disclosed example apparatus are also to, in response to a determination that no key mapping is associated with the combination of two or more context rules, map a key identifier to the combination of two or more context rules and generate a key corresponding to the key identifier. Disclosed example apparatus are further to encrypt the input data based on the key to obtain encrypted data.

Abstract: A system and method are disclosed associated with a cloud platform as a service provider. A monitoring agent, associated with a database service instance running on a client database virtual machine, periodically executes a performance throttling detection engine. The performance throttling detection engine gathers database statistics based on metrics and features of the database service using a rule-based approach. When it is determined that a pre-determined condition is met, the system may transmit the gathered database statistics to an external application. For example, the external application might comprise a database tuning service and the pre-determined condition may be associated with a decision that the database service may potentially need to tune knob configuration parameters (associated with memory knobs, background writer knobs, asynchronous knobs, etc.).

Abstract: Methods provide for fabricating objects through additive manufacturing in a manner that compensates for deformations introduced during post-print processing, such as sintering. An initial model may be divided into a plurality of segments, the initial model defining geometry of an object. For each of the segments, modified geometry may be calculated, where the modified geometry compensates for a predicted deformation. Print parameters can then be updated to incorporate the modified geometry, where the print parameters define geometry of the printed object (e.g., configuration settings of the printer, a tool path, an object model). The object may then be printed based on the updated print parameters.

Abstract: Computational methods and systems that troubleshoot and localize failures in data storage of a multitenant application are executed in a multitenant database management system that comprises a control plane of control plane nodes and a data plane of independent and isolated data plane nodes. Each control plane node receives data requests and data queries. Each data plane node maintains data storage for tenants of the multitenant application and executes data storage and data query operations requested by the control plane nodes. Methods and system determine whether data plane nodes are network connected and whether the data cores of network connected data plane nodes are available to ingest data and respond to data queries. Data cores of disconnected data plane nodes and unavailable data cores are isolated from data ingestion and data queries. Remedial measures are executed to restore disconnected data plane nodes and unavailable data cores.
