    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: The present invention provides an attack feature DNA generator comprising: an information processing unit collecting event information from a network environment; a factor extracting unit extracting normal factors and attack feature factors from the event information; a DNA generating unit analyzing correlation of the attack feature factor to the normal factor and generating an attack feature DNA which shows the correlation analysis result in a DNA structure; and a storing unit in which the event information and the attack feature DNA are stored. The present invention allows intuitively recognizing an ongoing attack type by comparing collected cyber-attack feature factors with cyber-attack feature DNAs.

    Abstract: Disclosed herein are an apparatus and method for authenticating an IoT device. The method, performed by the IoT device authentication apparatus, includes transmitting, by the IoT device authentication apparatus, a random number to the IoT device and encrypting, by the IoT device authentication apparatus, the random number using a previously registered first white-box cryptography value through a white-box cryptography method; generating, by the IoT device, a first device response value from a previously registered first device challenge value using a Physical Unclonable Function (PUF) and encrypting, by the IoT device, the random number, received from the IoT device authentication apparatus, using the first device response value; and performing, by the IoT device authentication apparatus, authentication of the IoT device by checking whether the random number encrypted using the white-box cryptography method matches the random number encrypted using the PUF, which is received from the IoT device.
