Abstract: An encryption security protocol-based communication method of supporting integrity verification between a client and a server includes receiving, by the server, a first message from the client, the first message including a request for a first integrity verification of the client so as to start a handshake of a transport layer security (TLS) connection, transmitting, by the server, a second message to the client, the second message including a request for first verification information for the first integrity verification, receiving, by the server, the first verification information from the client, and performing the first integrity verification by using the first verification information, and finishing the handshake and performing data communication between the client and the server based on a result of the first integrity verification.

Abstract: A method of verifying integrity of an Internet of Things (IoT) system including a hub device and a plurality of end-node devices includes: determining, by the hub device, a root device among the plurality of end-node devices; receiving, by the hub device, from the root device at least one root message authentication code generated based on a result of verifying integrity of a sub-tree of the root device, wherein the sub-tree of the root device comprises a subset of the plurality of end-node devices subordinate to the root device; and verifying, by the hub device, the at least one root message authentication code.
