The invention discloses a mobile terminal security authentication method based on a fragment block chain, and belongs to the field of Internet of Things security and information security. Based on a partial synchronous network, the maximum delay of communication among all nodes is as follows: one fragment of a block chain is maintained by each cluster by using a fragment block chain technology; a lightweight Byzantine fault-tolerant protocol is operated among the clusters so as to cancel independent command and decision functions of cluster head nodes, and a reasonable equipment registration, authentication and logout protocol is operated; therefore, multi-cluster parallel registration of the to-be-registered equipment, mutual authentication of the intra-cluster equipment and the inter-cluster equipment, a logout process of the intra-cluster equipment and cross-cluster transfer of the mobile terminal equipment are realized. According to the invention, the expandability of the networking ...
