Abstract: A secured storage device uses a user key set by user to encrypt a primary key that is for encryption or decryption of user data, to produce a first encrypted data. In the secured storage device, neither the primary key nor the user key is stored, but the first encrypted data, and a secondary key and a second encrypted data produced from the secondary key encrypted with the user key for verifying the password inputted by user are stored. Therefore, even though a storage medium in the secured storage device is detached and read, the primary key and the user key cannot be obtained by a third party for reading out any encrypted user data from the secured storage device.

Abstract translation: 安全存储设备使用由用户设置的用户密钥来加密用于用户数据的加密或解密的主密钥，以产生第一加密数据。 在安全存储装置中，不存储主键和用户密钥，而是用用于验证用户输入的密码的用户密钥加密的第二加密数据和辅助密钥以及第二加密数据， 存储。 因此，即使分离和读取安全存储设备中的存储介质，也不能由第三方从安全存储设备读出加密的用户数据来获得主密钥和用户密钥。
