  • Patent number: 10924382
    Abstract: Discussed herein is technology for verifiable network configuration repair. A method can include adding a routing adjacency or route redistribution edge to a router of an aETG to generate an enhanced aETG (eaETG), adding, for each dETG of dETGs, static route edges to a destination of the dETG to generate an enhanced dETG (edETG), determining, for each of the edETGs, all simple paths from all sources to the destination of the edETG, determining a set of paths (pathtset) over the determined simple paths that satisfies the policies, and translating the edge additions and/or removals in the eaETG and in the edETGs to an addition and/or removal of one or more of a routing adjacency, routing filter, or static route based on the determined pathset.

  • Patent number: 10285190
    Abstract: Generally discussed herein are systems, devices, and methods for scheduling node performance of communication and/or function. A method can include receiving, from a plurality of nodes, parameters indicating a trajectory and position of each of the plurality of nodes, creating a directed communication graph, creating a communications conflict graph, creating a function conflict graph indicating which function performed by one node of the plurality of nodes interferes with at least one of a function and communication performed by another node of the plurality of nodes, creating a universal conflict graph based on the communications conflict graph and the function conflict graph, creating a schedule for communication and function performance for each of the nodes based on the universal conflict graph, and providing data indicative of the schedule to nodes of the plurality of nodes.

  • Patent number: 9894043
    Abstract: Techniques for cryptographically secure, cross-domain information sharing are described. A first information domain including a first attribute-based encryption (ABE) authority defines a first universe of ABE attributes. Plaintext is encrypted using ABE encryption, producing ABE ciphertext. The ABE encryption uses an ABE access control expression defined with a set of ABE attributes comprising a first ABE attribute subset from the first universe of ABE attributes and second ABE attribute subset from a second universe of ABE attributes defined by a second ABE authority of a second information domain. The ABE ciphertext and the ABE access control expression are combined to produce an ABE package. The ABE package is encrypted, using predicate-based encryption (PBE), producing a PBE ciphertext. The PBE encryption uses a first set of PBE attributes from a universe of PBE attributes defined by a PBE authority.

  • Patent number: 9736860
    Abstract: Generally discussed herein are systems, apparatuses, and methods for scheduling node access to a shared resource. A method can include determining a position assignment for each of a plurality of nodes to create a ring schedule, the ring schedule defining time frames in which each node of the plurality of nodes has access to a resource that is shared among the plurality of nodes, the ring schedule comprising a plurality of epochs, and each of the plurality of epochs comprising a plurality of positions that define a time at which access to the resource begins, each of a plurality of nodes including a position assignment each epoch, and updating the ring schedule including permuting positions of the ring schedule with the position assignment remaining static or changing at least one position assignment in an epoch of the plurality of epochs.

  • Patent number: 9571463
    Abstract: Systems and techniques for policy-based access control in content networks are herein described. Content and metadata describing the content may be encrypted by using an access control policy and a cryptographic key associated with the access control policy. The access control policy may be defined with a set of access control attributes. Each node in the content-based network may be assigned a set of access control attributes and a cryptographic key generated as a function of its assigned set of access control attributes. Each node in the content-based network may be configured to decrypt successfully the metadata or the content if and only if the assigned set of access control attributes of the node satisfies the access control policy used to encrypt the metadata or content.
