    摘要： Embodiments of the present disclosure are directed to systems and methods for a zero-knowledge (zk) oracle (zkOracle) system that executes customized computation code for blockchain applications and secure the execution result by providing one or more zero-knowledge proofs (zkp). The disclosure provides a zkMiddleware structure (or blockchain middleware) and how zero-knowledge proofs can be applied for verifying blockchain states. This in turn enables data collection, verification, and process capabilities for blockchain-based applications by establishing credibility and trust based solely on verifiable blockchain technologies, computations, and underlying mathematics.

    摘要： Disclosed are various embodiments for binding the configuration state of client devices to the blockchain and utilizing the binding for managing cryptographic compliance. A management agent can send a request to a smart contract hosted by a blockchain network for a zero-knowledge proof (ZKP) of a configuration state for a computing device, the state including cryptographic policies. Cryptographic operations performed by the client device can be performed by complying with the policies stored on the blockchain network.

    摘要： A system and a method for digital proof generation are provided. The system includes a data management module to manage dataset having plurality of data rows and a query execution and verification module including a commitment storage sub-module, a query execution sub-module and a result verification sub-module. The data management module receives query from the query execution sub-module, related to operation on data rows of plurality of data rows, which is processed to generate execution result associated with data rows. The execution result is transferred along with data rows to the query execution sub-module. A set of commitments associated with execution result is transferred to the commitment storage sub-module. The query execution sub-module transfers set of commitments, from the commitment storage sub-module, and data rows to the result verification sub-module for verification, and receives a verification result from the result verification sub-module.

    摘要： This invention enables asynchronous encrypted communication under a protection of a simple password which must be communicated out-of-band. The password is easily communicable in-person, by telephone or by a text message. The invention assumes that one of the parties has an online device, such as a smartphone. After the encrypted session has been established, it can be used for a variety of cryptographic applications, such as encrypting or decrypting messages, sharing of cryptographic keys, and verifying data. The invention also has the secondary benefit of authenticating both parties to each other.
