Format-preservation release

Encryption without the mess, firm claims

Voltage Security has announced a software tool kit for adding format-preserving encryption to new and legacy applications.

Format-preserving encryption is a technique for applying strong encryption to specific fields of structured data stored in a database in a way that doesn't alter the size of the field, says Voltage spokesman Mark Bower. This has generally proven hard to do with encryption, but researcher Phil Rogaway pioneered a technique several years ago that Voltage is putting into practice in its SecureData tool kit, he says.

Sensitive data can be encrypted and still have its format preserved, says Bower.

The kit is well-suited for use in encrypting sensitive data associated with web services, he says.
