摘要： Methods, systems, and use cases for one-touch inline cryptographic data security are discussed, including an edge computing device with a network communications circuitry (NCC), an enhanced DMA engine coupled to a memory device and including a cryptographic engine, and processing circuitry configured to perform a secure exchange with a second edge computing device to negotiate a shared symmetric encryption key, based on a request for data. An inline encryption command for communication to the enhanced DMA engine is generated. The inline encryption command includes a first address associated with a storage location storing the data, a second address associated with a memory location in the memory device, and the shared symmetric encryption key. The data is retrieved from the storage location using the first address, the data is encrypted using the shared symmetric encryption key, and the encrypted data is stored in the memory location using the second address.

摘要： System and techniques for fault tolerant telemetry of distributed devices are described herein. A node includes a hardware component that receives telemetry from an entity resident on the node. The hardware component signs the telemetry with a cryptographic key to create signed telemetry and stores the signed telemetry in memory of the hardware component. Then, upon request from a remote entity, the hardware component provides the signed telemetry.

摘要： A computer system having data organized in files, having a secondary storage for storing files, having a primary storage, and having one or more types of file subsystems (file system implementations) for controlling transfer of files between primary storage and secondary storage. A subset of writes to secondary storage are performed using a Delayed Ordered Write (DOW) subsystem, which makes it possible for any file system to control the order in which modifications are propagated to disk. The DOW subsystem consists of two parts. The first part is a specification interface, which a file system implementation or any other kernel subsystem can use to indicate sequential ordering between a modification and some other modification of file system structural data. The second part of DOW subsystem is a mechanism that ensures that the disk write operations are indeed performed in accordance with the order store. DOW improves computer system performance by reducing disk traffic as well as the number of context switches that would be generated if synchronous writes were used for ordering.
