Abstract
Provided are an apparatus and method for guaranteeing the safety of a computing device by separating a closed domain from an open domain in the computing device and allowing the closed domain to perform key derivation that is required for encryption/decryption of data. The computing device includes a hypervisor, the open domain and the closed domain isolated from the open domain without being open to a user, the open domain and the closed domain managed by the hypervisor, and a key derivation executable code configured to generate an encryption key needed to perform encryption in the open domain, from a seed value, the key derivation executable code being executed in the closed domain, wherein the encryption key generated by the key derivation executable code is transferred to the open domain, and is automatically discarded after being used for encryption of data in the open domain.
