Abstract: Provided are a bit flipping device and method and a computer readable program for the same. The bit flipping device for input data having a two-dimensional array pattern includes: a clustering unit configured to generate at least one input data sequence based on the two-dimensional array pattern of the input data and classify the input data sequence into at least one cluster according to a preset method; and a bit flipping unit configured to perform bit flipping on erroneous bits in the input data sequence based on the classified cluster. Therefore, it is possible to further reduce inefficiency while further reducing system complexity compared to the existing error correction code-based bit flipping method by coupling the bit flipping device to an output side of a partial response maximum likelihood (PRML) detector to classify an output value of the PRML detector into at least one cluster and perform bit flipping based on the classified result.

Abstract: Provided is an apparatus for detecting and classifying malicious code. The malicious code detection and classification apparatus comprise a graph-generating unit configured to generate graph information from source data including a plurality of nodes corresponding to APIs included in the source data and one or more edges connecting between the plurality of nodes; a matrix-generating unit configured to generate an adjacency matrix between the APIs included in the source data using the graph information; and a machine-learning unit configured to detect malicious code included in the source data using the adjacency matrix as an input value for a machine-learning-based analysis model. According to the malicious code detection and classification apparatus, since a call graph between APIs is converted into an adjacency matrix, in which each row and each column are APIs, and used as an input value for a machine-learning-based analysis model, it has the advantage of being able to detect malicious code with a high detection rate and accuracy compared to the prior art.
