Vendors split on strategies for key management

Hardware encryption support is finally making its way into tape drives and tape libraries, but vendors are taking different approaches to encryption key management. Spectra Logic announced last May that its Spectra T120 and T950 libraries would ship with hardware-based encryption. In September, IBM and Sun Microsystems rolled out their respective System Storage TS1120 and StorageTek T10000 encrypted tape drives. And the LTO Consortium announced earlier this year its plans to add encryption to the LTO-4 tape drive specification, although details won't be released until early next year, according to IBM, a key member of the consortium. IBM's TS1120 drive uses RSA-2048 public key encryption to secure data encryption keys. The AES-256 data encryption key is encrypted with a company's public key and an optional third-party public key, both of which are then stored on four different locations on the tape. When the encrypted tape is read, the appropriate private key is used to decrypt the RSA-2048 data encryption key. "By using public ...

  • Hot technologies for 2007

    "Storage" magazine's editors reviewed technology developments, product introductions and storage standards to come up with this short list of must-have technologies for 2007. We believe iSCSI SANs, hardware-based tape encryption, high-capacity disk drives, virtualization and thin provisioning will have the greatest impact on enterprise storage environments.

  • SAN consolidation strategies

    As islands of SANs proliferate in companies, the cost of storage can soar. Sound SAN design strategies allow companies to reduce the number of SAN islands, strengthen a primary SAN, make storage easier to manage and provide more data protection.
