Abstract: Disclosed is an accelerator which includes a first to a K-th stage performing an NTT (Number Theoretic Transform) operation of first input data including a polynomial of a homomorphic ciphertext, the first to K-th stages being connected in series, and a first assist circuit generating a first to a K-th enable signal based on a degree of the polynomial of the first input data. Each of the first to K-th stages performs a butterfly operation of the first input data or corresponding output data of a previous stage in response to that the corresponding enable signal among the first to K-th enable signals indicates a first logical value, and bypasses the first input data or the corresponding output data of the previous stage in response to that the corresponding enable signal among the first to K-th enable signals indicates a second logical value.

Abstract: A method and apparatus for predicting the risk of the collision of an object are disclosed herein. The apparatus for predicting the risk of the collision of an object includes an information reception unit, an input processing unit, a risk calculation unit, and a provision unit. The information reception unit receives information transmitted by each of a plurality of heterogeneous transmission apparatuses. The input processing unit processes the information into input information required to calculate a degree of risk of a collision between objects. The risk calculation unit calculates the degree of risk of the collision between the objects using the processed input information. The provision unit externally outputs the degree of risk of the collision, and performs control so that the risk of the collision between the objects can be externally predicted.

Abstract: The present invention relates to an apparatus and method that control a vessel deviating from an anchorage using wide-range sensor-based spherical trigonometry. In the method, vessels anchored in an anchorage are monitored. The anchorage is defined as a group, and the group of the anchored vessels is managed. Leaving of a vessel, needing to deviate from the anchorage, from the group is controlled. If a vessel recognized as a vessel identical to one that left the group requests anchoring after a predetermined period of time has elapsed, the anchoring-requesting vessel is controlled.
