A secure booting apparatus according to an embodiment for solving the problems to be solved by the present invention includes: a memory configured to store encrypted data, an encrypted header, and a symmetric key; and a processor configured to generate decrypted data and a decrypted header by applying a symmetric key algorithm using the symmetric key to the encrypted data and encrypted header, to include a public key and a pre key generated from the public key in the decrypted header, to generate a comparison hashed message by applying a hash algorithm to the decrypted data, to generate a final verification value by applying a public key algorithm using the public key and the pre key to the decrypted header, to compare the comparison hashed message with the final verification value, and to determine that booting has failed if the comparison hashed message and the final verification value are different from each other.
