Abstract: Disclosed herein are an apparatus and method for detecting a malicious script. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program is configured to extract token-type features, each of which corresponds to a lexical unit, and tree-node-type features of an abstract syntax tree from an input script, to train two learning models to respectively learn two pieces of learning data that are generated in consideration of features extracted respectively from the token-type features and the node-type features as having the highest frequency, and to detect whether the script is a malicious script based on the result of ensemble-based malicious script detection performed for the script, which is acquired using an ensemble detection model generated from the two learning models.

Abstract: Disclosed herein is an apparatus and method for federated learning based on group key management. The apparatus receives learning group participation request information from a learning node that intends to participate in a federated learning group, updates a group key required for the learning node to participate in federated learning using a key material generated by hashing the learning group participation request information, decrypts an encrypted local variable received from the learning node and thereby updates the same to a global variable, and transmits the global variable to the learning node after encrypting the same using the updated group key.

Abstract: Disclosed herein are an apparatus and method for generating a data set. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program classifies collected data into numerical feature data and categorical feature data using a filter method, performs correlation analysis on the numerical feature data and the categorical feature data using an analysis of variance (ANOVA) method and a Chi-Squared method, and generates a data set for supervised learning and a data set for unsupervised learning using correlation scores calculated through correlation analysis.

Abstract: A method and an apparatus for integrated management/control of regionally distributed micro-cloud data centers. A system for managing distributed clouds includes an apparatus for managing distributed clouds and an apparatus for managing a plurality of micro-data centers. The apparatus for managing distributed clouds manages the plurality of micro-data centers, analyzes the service inputted by a user to generate optimal virtual resource information, and transmits it to the micro-data center. The micro-data center is allocated with optimal resource according to the inputted service analysis information and resource request information.
