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.

Abstract: Techniques for verifiable computation for cross-domain information sharing are disclosed. An untrusted node in a distributed cross-domain solution (CDS) system is configured to: receive a first data item and a first cryptographic proof associated with the first data item; perform a computation on the first data item including one or more of filtering, sanitizing, or validating the first data item, to obtain a second data item; generate, using a proof-carrying data (PCD) computation, a second cryptographic proof that indicates (a) validity of the first cryptographic proof and (b) integrity of the first computation on the first data item; and transmits the second data item and the second cryptographic proof to a recipient node in the distributed CDS system. Alternatively or additionally, the untrusted node may be configured to transmit a cryptographic proof to a trusted aggregator in the CDS system.

Abstract: Techniques for geospatial-temporal pathogen tracing in zero knowledge include: generating, by a first user device, a first proximity token for contact tracing; receiving, by the first user device, a second proximity token from a second user device; generating, by the first user device, a hash based on the first proximity token and the second proximity token; generating, by the first user device using a prover function of a preprocessing zero knowledge succinct non-interactive argument of knowledge (pp-zk-SNARK), a cryptographic proof attesting that an individual associated with the first user device tested positive for a pathogen; transmitting, by the first user device, first publicly verifiable exposure data including at least the cryptographic proof and the hash to a public registry; and applying at least the first publicly verifiable exposure data and second publicly verifiable exposure data to a machine learning model, to obtain actionable intelligence associated with the pathogen.

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.

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 (pathset) 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.

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.
