摘要

Provided are: an entry/exit management system that suppresses the possibility of unauthorized access; an authentication device, a management device, a portable terminal, and a mobile unit that constitute the entry/exit management system; a data structure for entry/exit management data that is to be used in the entry/exit management system; an entry/exit management program that is to be executed by the entry/exit management system; and a construction method for the entry/exit management system. According to the present invention, a plurality of nodes that are connected by a P2P network share a blockchain. Authentication conditions are recorded in a block of the blockchain by a management node that is any of the plurality of nodes. The authentication conditions include authentication information for passing people who have portable terminals or for authenticatable passing bodies such as mobile units. The authentication conditions designate an authentication node that is any of the plurality of nodes as a node for performing authentication. When authentication information for a passing body that has been read by the authentication node that is designated in the authentication conditions is included in the authentication conditions, the passing body is authenticated by the authentication node.
