Abstract: Disclosed are a system for interoperating DHT-based overlay networks and a method thereof. The system for interoperating DHT-based overlay networks includes a domain participation node inquiring an address of a node in which a file is stored in a predetermined domain management node when there is no node storing a file to be used in a unit overlay network which the domain participation node itself belongs to; and a domain management node providing the address of the node storing the file by interoperating at least one different unit overlay network in accordance with the inquiry of the domain participation node.

Abstract: An application programming interface (API) authentication method using two API tokens which includes issuing a general API token and providing information required for a one-time API token to a user device; and in response to an API request from the user device, processing an API request according to a result of authentication based on the general API token and a one-time API token, which is generated using the information required for a one-time API token creation.
