Information Operations is a category of direct and indirect support operations for the United States Military. By definition in Joint Publication 3-13, "IO are described as the integrated employment of electronic warfare (EW), computer network operations (CNO), psychological operations (PSYOP), military deception (MILDEC), and operations security (OPSEC), in concert with specified supporting and related capabilities, to influence, disrupt, corrupt or usurp adversarial human and automated decision making while protecting our own." Information Operations (IO) are actions taken to affect adversary information and information systems while defending one's own information and information systems.
A password algorithm artificial intelligence side channel analysis method based on dimension reduction and clustering
ActiveCN117579244BCryptographic attack countermeasuresEnergy efficient computingCluster algorithmPrincipal component analysis
The present application relates to a kind of password algorithm artificial intelligence side channel analysis method based on dimension reduction and clustering, belong to information security cryptography field.First, the energy trace obtained is analyzed, to determine the area of the energy trace in which the execution of the decryption process is related to secret information operation.Analyze the energy trace of the key operation part, use the method based on sliding window gradient value to divide each operation, obtain energy trace segment.Combined with the implementation of cryptographic algorithm, the energy trace segment is analyzed, and the operation type is identified.Use principal component analysis on energy trace segment for dimension reduction, take the component corresponding to the expected dimension as the principal component of each operation.Combined with the characteristics of energy trace segment, the cluster number obtained by clustering is estimated.Use clustering algorithm to cluster the energy trace segment after dimension reduction, analyze the clustering result to determine the operation type represented by each cluster, obtain the operation type corresponding to the energy trace segment, finally obtain the secret index sequence, realize the efficient analysis of the side channel of cryptographic algorithm.

A network information operation and maintenance system based on AI multimodality
This invention provides an AI-based multimodal network information operation and maintenance system, belonging to the field of network information operation and maintenance technology. The system collects heterogeneous operation and maintenance data such as network traffic, device status, audio alarms, and thermal imaging through a data acquisition unit. It utilizes a multimodal feature extraction module to extract various features in parallel, forming a unified multidimensional feature vector. A hierarchical anomaly detection architecture is established, deploying lightweight and deep anomaly detection models at the edge and cloud respectively. A multimodal feature fusion model intelligently fuses different modal features through an attention mechanism. An adaptive threshold dynamically adjusts the Bayesian algorithm to optimize the detection threshold in real time based on network status. A multimodal fusion decision engine is constructed to weight and fuse anomaly detection results and dynamically adjust modal weights, thus solving the technical problem of insufficient accuracy in multimodal operation and maintenance data fusion processing.

Power grid information operation and maintenance active early warning method and system based on data analysis
This invention discloses a proactive early warning method and system for power grid information operation and maintenance based on data analysis, belonging to the field of power grid operation and maintenance technology. The method includes the following steps: acquiring a set of alarm data output by the power grid operation system; diagnosing and extracting initial root cause features from the alarm data set; comparing power grid business indicator data with preset recovery target thresholds; extracting actual effective operation data from manual intervention records; generating a knowledge conflict record set; updating the recommended priority sequence in the handling strategy library based on the actual effective operation data; and applying the corrected causal weight matrix and the updated handling strategy library for early warning. This invention solves the problems of existing early warning models being unable to adapt to business changes, lacking self-correction mechanisms, and prone to secondary faults due to misjudgment by setting up a handling effect observation window to identify invalid operations and tracing back to effective manual operations.
