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 a method of analyzing a container system call configuration error, including: profiling a set of trusted images that are uploaded to a public or private container image repository during initialization of a system or verified by a repository owner; identifying a custom service layer and known service layers based on the trusted image when a custom image is transmitted to the system; analyzing only the custom service layer by a system call extraction engine; and generating and optimizing a profile with an essential and non-malicious system call by scanning the custom service layer to remove a malicious program or a vulnerable system call. Accordingly, it is possible to reduce overhead by omitting re-analysis of known images in a container image scanning process.

Abstract: This application relates to an apparatus and method for generating a jamming signal, and a communication system. In one aspect, the method may include converting binary bits of a first communication signal to be transmitted and obtaining at least one codeword matched previously to the binary bits. The method may also include generating a second communication signal by superimposing a first conversion signal being obtained by converting the first communication signal to an up-chirp signal and a second conversion signal being obtained by converting the first communication signal to a down-chirp signal. The method further include generating a pseudo jamming signal by computing the second communication signal and the codeword.
