Patent number: 8832842Abstract: An external security device is provided in the communication path between devices of different security levels. A higher security device needs only to trust the security of the external device, rather than relying on operating system and file system software that cannot be assured. The external security device blocks access requests that may be using covert channels, but returns status information that indicates that the request is successful. The external security device may then audit access requests to provide a higher level of accountability. The external security device also handles data duplication to prevent or significantly reduce the threat of traffic analysis.Type: GrantFiled: October 7, 2003Date of Patent: September 9, 2014Assignee: Oracle America, Inc.Inventor: James P. Hughes

A first time stamping process for creating a first time stamp for a data object based on instructions applied by the controller for storage on the WORM server. A second time stamping process for creating a second time stamp for the data object for storage on the WORM server. The second time stamping process creates the second time stamp for the data object and first time stamp to ensure the integrity of the data object stored on the system.Type: GrantFiled: August 8, 2007Date of Patent: January 14, 2014Assignee: Oracle America, Inc.Inventor: James P.

Patent number: 8225086Abstract: A system that remotely authenticates a command is presented. During operation, an authentication system receives the command from an intermediary system, wherein the command is to be executed on a target system. Next, the authentication system authenticates the intermediary system. If the intermediary system is successfully authenticated, the authentication system authenticates the command using a private key for the authentication system to produce an authenticated command. Next, the authentication system sends the authenticated command to the intermediary system, thereby enabling the intermediary system to send the authenticated command to the target system so that the target system can use a public key for the authentication system to verify and execute the command.Type: GrantFiled: November 13, 2007Date of Patent: July 17, 2012Assignee: Oracle America, Inc.Inventors: Christoph L. Schuba, James P. Hughes

Publication number: 20120066518Abstract: Security is provided for a data set stored in a data storage canister. The data set has a data size when received for storage within the canister. At least one data security operation is performed on the received data set to generate secure data having a secure data size that may be different than the set data size. The secure data is stored on at least one data storage device within the canister. Any information about the secure data size is kept from the data producer sending the data set for storage.Type: ApplicationFiled: August 2, 2011Publication date: March 15, 2012Applicant: STORAGE TECHNOLOGY CORPORATIONInventors: Steven H. McCown, Stephen S. Selkirk, Charles A. Milligan, James P. Hughes, Jacques Debiez

Patent number: 8064606Abstract: A system that securely registers components in a first system is presented. During operation, the first system receives a request from an intermediary system to obtain configuration information related to the components in the first system. In response to the request, the first system: (1) encrypts configuration information for the first system using a first encryption key; (2) encrypts the first encryption key using a second encryption key; and (3) sends the encrypted configuration information and the encrypted first encryption key to the intermediary system so that the intermediary system can forward the encrypted configuration information and the encrypted first encryption key to the second system, whereby the encrypted configuration information is cryptographically opaque to the intermediary system. Next, the second system uses the configuration information to register the components in the first system.Type: GrantFiled: November 13, 2007Date of Patent: November 22, 2011Assignee: Oracle America, Inc.Inventors: Christoph L. Schuba, James P. Hughes, Daniel E. Smith
