Patent ID: 8335915

Claim:
A method for operating a security device for securely storing data, comprising: converting a directory into a cryptainer by encrypting data stored in the directory, wherein the directory is accessible by the security device as an exported share from a server, via a first network interface, using a first data access protocol; receiving, via a second network interface, a clear text message to access the directory using a second data access protocol, the clear text message comprising a name of the director, and a credential, the directory comprising a special file having a property that it cannot be read or deleted via the second network interface, the special file having an identifier of the cryptainer (cryptainerID) and having permissions for access to the cryptainer; accessing, via the first network interface, the special file, extracting the cryptainerID from the special file, and checking the credential against the permissions in the special file, wherein the security device distinguishes between data, command, and status information, wherein a command is passed through the encryption device unmodified except for a pathname, and wherein the data associated with the command is encrypted; reading the encrypted data from the directory, and decrypting the encrypted data in response to the credential having permission to access the data; and in response to the clear text message, transmitting the decrypted data via the second network interface.
