Abstract: Disclosed herein are an attack detection apparatus and method based on measurement of networking behavior abnormalities in symbolic spaces. The attack detection method based on measurement of networking behavior abnormalities in symbolic spaces includes creating profiles based on a transmission address of a flow received from a network, measuring a behavior abnormality of a device corresponding to the transmission address of the flow on the network, and mapping the measured behavior abnormality to behavior symbols in symbolic spaces, generating a behavior symbol sequence pattern, in which the behavior symbols are sequentially connected, for each profile, and detecting presence or non-presence of an attack and a device associated with the attack based on an output of the abnormal behavior prediction model that receives the behavior symbol sequence pattern as input.

Abstract: Disclosed herein are a finite-field division operator, an elliptic curve cryptosystem having the finite-field division operator, and a method for operating the elliptic curve cryptosystem. The method for operating an elliptic curve cryptosystem may include, setting, by a key setting unit, a length of a key of a cryptographic algorithm, generating, by the key setting unit, first setup information that indicates a number of words corresponding to the key length, and generating, by the key setting unit, second setup information that indicates a number of repetitions of an operation by a finite-field division operator corresponding to the key length.

Abstract: A method for detecting anomalies in a controller area network of a vehicle and an apparatus for the same. The method for detecting anomalies in a Controller Area Network (CAN) of a vehicle includes monitoring the controller area network of the vehicle and generating sequence trees for respective multiple sub-networks included in the controller area network at a time at which monitoring is performed, comparing at least one normal sequence tree, generated in accordance with the controller area network when a status of the vehicle is normal, with the generated sequence trees, and calculating differences between traffic proportions for respective nodes based on a result of the comparison between the sequence trees, and detecting an anomaly in the vehicle in consideration of the differences.
