Access "Vendors split on strategies for key management"

Published: 20 Oct 2012

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 key cryptography and storing ... Access >>>
