The era of quantum computers that go beyond the performance of supercomputers came to the front. The telecommunications industry is also accelerating technology development in order to develop competitiveness in the quantum cancer telecommunications market. According to the industry on the 14th, SK Telecom and KT have a quantum cancer hooki distribution (QKD) application method, while LG Uplus is developing technology using quantum resistance (PQC) to future the Internet of Things (IoT), Finance, City Airlines. The plan is to use it for security in various areas such as the mobility (UAM) field. QKD is a method of increasing security by creating a cryptocurrent key that can only decipher the transmitter and receiving parts. Since the process of sending and receiving information to create a secret key is proceeded in the quantum state, the third party does not know any information about the encryption key. PQC is a method of creating and using a password that is difficult to solve u
