Zusammenfassung:	The invention discloses an intelligent networked automobile OTA remote security upgrading method and system, and the method comprises the steps: decomposing a current OTA software upgrading package into a plurality of software upgrading sub-packages, sequentially solving a HASH value of each software upgrading sub-package, constructing a Merkle tree according to the HASH values, calculating the HASH value of the root of the Merkle tree, and carrying out the remote security upgrading of the OTA software upgrading package according to the HASH value of the root of the Merkle tree; after the software upgrading subpackages are transmitted to the ECU-UA by the UC-master through the gateway or the domain controller, the HASH value of each software upgrading subpackage is solved again, the Merkle tree is reconstructed again according to the HASH values, the HASH value of the root of the Merkle tree is solved again, and the two HASH values are compared. If the two are equal, starting a normal upgrading program; and o
