Abstract
A secure storage system is disclosed. The secure storage system comprises a crypto engine and a storage device. The crypto engine comprises a random number generator; a hash function; a general encryption engine; and a data encryption engine. The secure storage system further includes a storage device coupled to the crypto engine. The storage device includes a storage array. The storage array includes a public partition, a secure partition and a system partition. The public partition is accessible to the public. The secure partition is accessible through the password authentication. The system partition is accessible only by the secure storage system. The password authentication is two-level instead of one, to avoid hash collision or insider tampering. The secure partition is accessed with “access gating through access key” instead of “access control through comparison.” The password can be changed without reformatting the secure storage.
