Abstract
A storage device includes: a non-volatile memory for storing a firmware set including a firmware image encrypted using a symmetric key and an encrypted symmetric key generated by encrypting the symmetric key using a public key; and a storage controller for controlling the non-volatile memory, wherein the storage controller includes: a physically unclonable function (PUF) chip having a unique security key; and a one-time programmable (OTP) memory for storing an encrypted secret key generated by encrypting a secret key paired with the public key using the PUF chip, wherein a firmware image is obtained by loading the firmware set, providing the encrypted secret key to the PUF chip, receiving the secret key from the PUF chip, generating the symmetric key by decrypting the encrypted symmetric key using the secret key, and decrypting the encrypted firmware image using the symmetric key.
