Storage developers need to understand that the algorithms and protocols used for data protection are in the midst of significant changes. This is driven by increases in the size of storage devices, the complexity of large data storage systems, discoveries of weaknesses, and improvements in attacks on encryption. Storage devices are seeing changes in block encryption algorithms and in implementations of those algorithms. Post-quantum cryptographic (PQC) algorithms will improve resistance to attacks using quantum computers, and a new timeline is in effect for adoption of those algorithms. Various protocols are being updated to use the new algorithms and to manage the transition to PQC.
