The invention provides an elevator connection equipment confirmation system and an elevator connection equipment confirmation method, which can confirm whether external equipment is normal equipment or not without adding a new device or channel. A main controller (50) of an elevator system (100) according to one embodiment of the present invention comprises: a communication path selection unit (52) that selects any one of a plurality of controllers as a sub controller (60); an encryption unit (54) that generates encrypted data by encrypting information including at least identification information of the sub-controller (60) using the public key (31) acquired from the node (30); and a determination unit (59) that determines that the node (30) is an irregular device when transmission source information of an information group transmitted from the controller identified by the node (30) as a transmission source does not match the information of the sub-controller (60).
本发明提供一种电梯连接设备确认系统和电梯连接设备确认方法,无需追加新的装置或信道就能够确认外部设备是否正规设备。本发明的一个方式的电梯系统(100)的主控制器(50)包括:选择多个控制器中的任一个作为副控制器(60)的通信路径选择部(52);加密部(54),其使用从节点(30)获取的公开密钥(31),对至少包括副控制器(60)的识别信息的信息进行加密来生成加密数据;和判别部(59),其在将被节点(30)识别出的控制器作为发送源发送来的信息组的发送源信息与副控制器(60)的信息不一致的情况下,判断为节点(30)是非正规设备。
