The present embodiments relate to implementing change data on no-master NoSQL data stores. An optimized node can be identified from a plurality of NoSQL data storage nodes and a specialized node can be connected (e.g., collocated) to the optimized node. The specialized node can maintain change data capture (CDC) data provided by client nodes in a hash map that can be used as a point of truth for coordinating CDC data across the plurality of NoSQL data storage nodes. The plurality of NoSQL data storage nodes can identify and coordinate all read/write data obtained from multiple client devices in a geographically separated large-scale (e.g., planet scale) system to identify change data in a distributed data store. The specialized data can provide read data to devices in the large-scale system to reconcile inconsistencies in change data across nodes in the large-scale system.

Methods and systems for memory tracing in asset managing systems

Systems and methods for memory tracing in asset managing systems

Techniques are disclosed for enabling attested end-to-end encryption for transporting data between devices. In one example, a destination device receives a policy profile that includes an origination key and a destination key, and the origination key corresponds to a public transfer key of a source device. The destination device verifies the policy profile based on the destination key corresponding to a public transfer key of the source device. The destination device receives a signed encrypted data encryption key from the source device. The destination device receives encrypted data from the source device. The destination device verifies the signed encrypted data encryption key originated from the source device based on the signed encrypted data key being signed with a private attestation identity key that corresponds to a public attestation identity key of the source device. The destination device decrypts encrypted data using a private transfer key of the destination device.

Attested end-to-end encryption for transporting sensitive data

The present disclosure relates generally to systems and methods for content authentication. A method can include receiving from a sender system transmitted content (C) and appended content, the appended content including a digital signature associated with the content (C) and a hash tree ('SHT') associated with the content (C), generating with a signature engine a hash tree ('RHT') from the content (C), cryptographically verifying the received digital signature to generate a resultant hash value, comparing the resultant hash value to the second hash value of the second root node, determining that the second hash value of the second root node does not match the resultant hash value, identifying a potentially corrupted portion of content (C) via comparison of at least some of the plurality of first nodes of SHT to corresponding second nodes of RHT, and indicating that the digital signature could not be verified.

Efficient and scalable mechanism to protect integrity and authenticity of large data sets in cloud logging environments

Techniques are disclosed for tracing memory components in asset management systems. A computing device may receive an indication that a new device has been connected to a network. The computing device receives a first set of memory specifications from the new device and a second set of memory specifications from a SoV database. The computing device then generates a memory-asset data structure that stores a third set of memory specifications, each memory specification of the third set of memory specifications being a memory specification that is in both the first set of memory specifications and the second set of memory specifications. The computing device assigns, memory specifications of the third set of memory specifications, a data privacy level that is based on a sensitivity of data stored in the component of the new device. The computing device may then transmit the memory-asset data structure.

Methods and systems for memory tracing in asset management systems

Techniques are disclosed for enabling attested end-to-end encryption for transporting sensitive data between devices. In one example, an origination device receives and verifies, in a secure environment, a policy profile that includes an origination key of the origination device and a destination key of a destination device. The origination device generates and seals a data encryption key based on a characteristic of the secure environment. The origination device then encrypts the data encryption key with a public key of the destination device to form an encrypted data encryption key. The origination device then signs the encrypted data encryption key with a private attestation identity key of the origination device. The origination device encrypts the sensitive data with the sealed data encryption key to form encrypted data, and then transmits the signed encrypted data encryption key and the encrypted data to the destination device for subsequent decryption of the encrypted data.
