Abstract: In general, this disclosure describes techniques for a computing system configured to obtain a plurality of records indicating historical traffic flows for an application having application instances executing at a plurality of data centers. The computing system may be configured to determine, based on the plurality of records, whether a current network configuration will satisfy service level expectations (SLEs) for the application, the current network configuration including first configuration information for a first set of links. The computing system may be configured to, based on determining the current network configurations will not satisfy the SLEs for the application: generate, based on the plurality of records and the SLEs, a new network configuration including second configuration information for a second set of links; provision, based on the new network configuration, the second set of links at the plurality of data centers to facilitate the traffic flows among the application instances.

Abstract: The present disclosure provides a method for generating and verifying a non-interactive zero-knowledge proof with subversion zero-knowledge security against malicious common reference strings. The method includes providing a non-interactive zero-knowledge proof system with subversion zero-knowledge security, generating and verifying the proof using a combination of a provided non-interactive zero-knowledge proof system, a delayed-input two-message publicly-verifiable S-notion zero-knowledge argument system, and a non-interactive perfectly binding and T-extractable commitment scheme. The method further includes generating a common reference string, generating a proof, and verifying the proof for an outer NIZK system. The system comprises generating an inner common reference string, computing a first message, computing a second message, committing to the second message, computing an inner proof, and verifying the inner proof using an inner NIZK system.

Abstract: Systems and methods for a blockchain-based system for efficient storage and retrieval of disparate supply-side transaction information. An example embodiment includes features to receive a transaction from a provider system; aggregate the received transaction with a plurality of other transactions, wherein each transaction is encrypted; generate one or more hashes associated with the aggregated transactions, and broadcast the generated hashes onto a blockchain of a blockchain network; store the encrypted transactions and generated hashes, wherein the computer system is configured to respond to a search request received from a user, and wherein the computer system is further configured to validate stored transactions which are responsive to the search request via comparison to the generated hashes on the blockchain.
