While some storage-product companies already support one sort of encryption or another, having standard implementations could make it easier for customers to safeguard data across heterogeneous storage environments, standards supporters say.
The proposed standards define three encryption algorithms and a method of key management designed to ensure the compatibility and interoperability of different storage gear. For encryption on disk, the specification proposes using the new Liskov, Rivest, Wagner-Advanced Encryption Standard (LRW-AES) cryptographic algorithm. For tape encryption, it proposes using the National Institutes of Standards and Technologies' (NIST) AES Galois/Counter Mode (AES-GCM) and AES Counter with CBC-MAC Mode (AES-CCM) standards.
Galois/Counter Mode? BTW this article's comments about CBC are wrong. You cannot do arbirary data mangling in CBC. He is thinking of ECB. The problem with CBC is its slow...
