June 24, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- International Business Machines Corporation (Armonk, NY) has been issued patent number 8750516, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Goodman, Brian Gerard (Tucson, AZ); Fisher, James Arthur (Tucson, AZ); Jaquette, Glen Alan (Tucson, AZ); Jesionowski, Leonard George (Tucson, AZ).

This patent was filed on January 4, 2012 and was published online on June 10, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "The present invention relates to a method, system, and article of manufacture for rekeying encryption for removable storage media.

"Data stored in removable media cartridges may be encrypted by an encryption engine to protect the data. Data encryption is especially useful for businesses that store personal data on their customers. Recent government regulations place requirements and legal obligations about companies storing personal data to report any loss of storage media containing personal information which was not encrypted.

"If a user wants to change the encryption key used to encrypt data in a removable storage cartridge, then the user must initiate operations to decrypt the data in the cartridge and then re-encrypt the data using the new encryption key. The encryption keys used to encrypt and decrypt data in removable media cartridges may be maintained by a key server having a key store or database external from the storage drive.

"There is a need in the art for improved techniques to provide a new encryption key to use for a data cartridge."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "Provided are a method, system, and article of manufacture for rekeying encryption keys for removable storage media. A rekey request is received for a coupled removable storage media, wherein encryption on the coupled removable storage media uses a first key and wherein the rekey request indicates a second key. The first key and the second key are accessed in response to the rekey request. The first key is used to perform decryption for the coupled removable storage media and the second key is used to perform encryption for the coupled removable storage media."
