An information protection method based on software-defined perimeter (SDP) for Internet of Things (IoT) cloud security may comprise: receiving, at an SDP controller, an onboarding request message with an identity (ID) token from an SDP client acting as an initiating host, the onboarding request message comprising information requesting authentication of the SDP client and a handshake parameter specifying a handshake protocol for use in an SDP access process; and issuing, at the SDP controller, an SDP client credential corresponding to the handshake parameter.

A Merkle tree-based data management method may comprise: aligning data into two-dimensional square matrix; calculating a hash value of each node of the two-dimensional square matrix; calculating hash values of each row of the two-dimensional square matrix; generating an additional column with nodes having the hash values of each row; calculating hash values of each column of the two-dimensional square matrix; generating an additional row with nodes having hash values of each column; and calculating a Merkle root by concatenating the hash values of the additional column and the hash values of the additional row.
