Abstract
The present disclosure relates to technology that performs encrypted communication via a network or a bus, and a communication method using a security key between nodes connected via a network or a bus includes setting a critical cluster among multiple nodes, selecting a primary message shared between the set critical clusters, and encrypting a message using a key generated to be valid for a preset period to enable communication between the critical clusters, wherein each of the critical clusters stores the primary message for the preset period according to a same key generation scheme to generate a block, and generates and possesses a new key based on the generated block and a currently used key, so that information about a previous message and a previous key is sequentially accumulated in the new key.
