Abstract: Methods and systems are presented for providing a multi-party computation (MPC) framework for dynamically configuring, deploying, and utilizing an MPC system for performing distributed computations. Based on device attributes and network attributes associated with computer nodes that are available to be part of the MPC system, a configuration for the MPC system is determined. The configuration may specify a total number of computer nodes within the MPC system, a minimum number of computer nodes required to participate in performing a computation process, a key distribution mechanism, and a computation processing mechanism. Encryption keys are generated and distributed among the computer nodes based on the key distribution mechanism. Upon receiving a request for performing the computation, updated network attributes are obtained.

Abstract: A method and device for monitoring production equipment and a storage medium includes: a measurement result of production equipment to be monitored is acquired; the measurement result of the production equipment to be monitored is evaluated on at least one evaluation dimension to obtain an evaluation result on each evaluation dimension; and a production state of the production equipment to be monitored is determined based on the evaluation result on the at least one evaluation dimension. The production state includes a normal state and an abnormal state. The at least one evaluation dimension includes at least one of a process level of products, a statistical significance of products or a distribution trend of products.

Abstract: A method for detecting abnormal network data includes performing feature extraction on a network data packet according to each of plural protocol types, and generating a corresponding data packet fingerprint set. The data packet fingerprint set includes one or more data packet fingerprints, each of the one or more data packet fingerprints corresponding to one of the plural protocol types. The method further includes matching at least one data packet fingerprint in the data packet fingerprint set and a reference data packet fingerprint in a reference data packet fingerprint library, and calculating a confidence corresponding to the network data packet based on confidence correlation information corresponding to each of the at least one matched data packet fingerprint. The method also includes obtaining a reference confidence, and determining an abnormality detection result of the network data packet based on the reference confidence and the calculated confidence.

Abstract: Methods and systems are presented for providing a secured framework for facilitating electronic transactions using a multi-party computation approach. Under the multi-party computation approach, the task of authenticating a transaction conducted through a user account is distributed among multiple computer nodes. One or more secrets and shares of a secret are distributed among the multiple computer nodes. An authentication process is implemented such that at least a portion of the multiple computer nodes, including one or more required nodes, exceeding a predetermined number of nodes are needed to perform a set of computations using the corresponding secret(s) and/or shares of the secret in order to generate a digital signature for the user account. By verifying the digital signature using a public key of the user account, it can be determined that the participation requirement has been satisfied.
