    Abstract: Disclosed herein is an apparatus and method for drone control data security. The apparatus includes memory in which at least one program is recorded and a processor for executing the program. The program may encrypt control data in a unit of a block based on a counter block configured using a nonce value and transmit the encrypted control data to a drone along with a nonce change reference counter value, the nonce value initialized to an initial nonce value may change sequentially according to a predetermined sequence each time the control data in a unit of a block is encrypted, and the nonce change reference counter value may increase each time the nonce value changes.

    Abstract: A technology enabling a terminal to receive acknowledgement (ACK)/negative ACK (NACK) information about data transmitted from the terminal is provided. The method includes receiving cyclic shift information for a reference signal from the base station; transmitting, to the base station, the data and a reference signal which is cyclic-shifted using a cyclic shift value, the cyclic shift value being determined based on a dynamic cyclic shift value mapped one-to-one to the cyclic shift information for the reference signal; and receiving, from the base station, the ACK/NACK information about the transmitted data through a radio resource of a downlink channel, the radio resource of the downlink channel being identified based on a modifier mapped one-to-one to the cyclic shift information for the reference signal.

    Abstract: Provided are a device and method for artificial intelligence (AI) reasoning based on a language model. The method for AI reasoning based on a language model includes generating a question core summary by inputting a natural language question to a language model, decomposing the natural language question into sub-questions using a reasoning model on the basis of the question core summary and the natural language question, obtaining an answer to the natural language question by solving the sub-questions and synthesizing solutions of the sub-questions.

    Abstract: Disclosed herein is a method for security performance evaluation for determining a defensive execution function. The method includes determining performance criteria data for a defensive execution function by performing static analysis of a protection target program, receiving a performance level specification for the defensive execution function, injecting the defensive execution function within a defensive execution function pool into the protection target program, injecting code for measuring the security performance of the defensive execution function into the protection target program, measuring the security performance data of the protection target program, and determining a combination of defensive execution functions within the defensive execution function pool based on the security performance data.

    Abstract: Provided is a downlink control information transmitting and receiving method which can maximize the use of limited radio resources by effectively forming an uplink signaling message to be transmitted from a base station to a terminal and transmitting the formed uplink signaling message with a minimum amount of radio resources occupied. The method for transmitting downlink data generation indication information for a base station to inform a terminal of packet data transmission in a packet-based cellular system, includes the steps of: a) generating the downlink data generation indication information; b) recording radio resource allocation information in downlink scheduling information for transmitting the downlink data generation indication information, and allocating information for the downlink data generation indication information to downlink-shared radio resources; and c) transmitting the downlink scheduling information and the information for the downlink data generation indication information according to a transmission cycle.
