DDOS attack detection method, medium and equipment

The invention discloses a DDOS attack detection method, a medium and equipment. The method comprises the following steps: collecting traffic data packets of a plurality of nodes in a target block chain; preprocessing the traffic data packet collected in a preset first time period to obtain multi-dimensional structure data; performing calculation according to the multi-dimensional structure data to obtain an entropy value of the multi-dimensional structure data; and comparing the entropy value with a preset entropy threshold value to judge whether the target block chain is subjected to the DDOS attack or not, so that whether the block chain is subjected to the DDOS attack or not can be detected timely and accurately, and the multi-dimensional structure data can fully retain the features left when the block chain nodes are accessed on the premise of not occupying a large amount of storage space. 本发明公开了一种DDOS攻击检测方法、介质及设备，所述方法包括：采集目标区块链中的多个节点的流量数据包；对在预设第一时间段内采集到的所述流量数据包进行预处理，得到多维结构数据；根据所述多维结构数据进行计算，得到所述多维结构数据的熵值；
