Abstract: The technical idea of the present invention relates to a method for forming a virtual private network and a virtual private network operating system, which provide a virtual private network by performing signature and authentication based on a post quantum cryptography. A method for forming a virtual private network performed by a server according to the technical idea of the present invention comprises the steps of: generating a private key including a first key vector corresponding to a grid and a second key vector having a first distance from the first key vector; receiving a handshake request from a client; performing a signature by using the private key; and transmitting a certificate and an authentication message including the signature to the client.

Abstract: The technical idea of the present invention relates to a mobile robot for monitoring a network and a method for operating the same. According to the technical idea of the present invention, a method for operating a mobile robot for detecting at least one network comprises the steps of: moving to a first location; detecting a first network in the first location; determining whether the first network is an authorized network; determining the threat of the first network when the first network is not the authorized network; and transmitting information on the first network when the first network is determined as a threat as a result of the determination of the threat.

Abstract: The technical idea of the present invention relates to a method for forming a virtual private network based on post-quantum cryptography and a virtual private network operating system performing the same. The method for forming a virtual private network performing by a first device to form a virtual private network with a second device according to an embodiment of the present invention comprises the steps of: requesting a handshake for forming the virtual private network; receiving a signature and a public key; authenticating the second device by using the signature; generating a symmetric key by using the public key; and performing virtual private network communication by using the symmetric key, wherein the public key is generated by using at least one key vector corresponding to a grid.

Abstract: The present inventive idea relates to a method for forming a Bluetooth network which authenticates through an authentication code generated based on post-quantum cryptography and a Bluetooth network operating system performing the same. The method for forming a Bluetooth network performed by a master device to perform Bluetooth communication with a slave device according to an embodiment of the present disclosure may include: obtaining an address of the slave device by scanning the Bluetooth network; generating a public key and a private key; transmitting the public key to the scanned slave device; receiving a key capsule and an authentication code corresponding to the public key; generating a verification code by using the key capsule; generating a symmetric key by comparing the verification code with the authentication code; and performing communication through the Bluetooth network by using the symmetric key.
