Apparatus for generating a signature that reflects the similarity of a malware detection and classification system based on deep neural networks, method therefor, and computer-readable recording medium recorded with a program for performing the method

An apparatus for generating a signature that reflects the similarity of a malware detection and classification system, the apparatus comprising:

• a pre-processing unit configured to generate an input vector from input information which is information on a file whose malware classification is unknown;
• a classification unit configured to calculate a latent vector which indicates the similarity between at least one malware classification and the input vector by performing a plurality of computations to which learned weights of a plurality of layers are applied on the input vector through a deep neural network model;
• and
• a signature generation unit configured to generate a signature of the malware in a form of a binary vector by quantizing the latent vector.
