Abstract: The present invention relates to security service providing apparatus and method for supporting lightweight security which provides lightweight security by using an error coefficient and a hash of a chain block used for time synchronization with the terminal for generation of an encryption key to improve security complexity while securing security for communication with terminals and also securing security for an encryption key through the blockchain. According to the present invention, for security for the communication session between the service providing apparatus and the terminal, the encryption key of the terminal is generated as the hash through the hash algorithm by combining the time difference generated in the time synchronization process with the terminal and the hash generated based on the information related to the encryption key of the other terminal stored in the blockchain to generate a symmetrical encryption key which cannot be inferred and has high security.
