New Features and Enhancements

Luna HSM firmware 7.8.2 includes the following new features and enhancements:

Clusters and Keyrings Feature Enhancements


Clusters are presented as a technical preview, to give customers the opportunity to validate our new HSM management features, designed to reduce operation cost and maximize the return on investment of a fleet of HSMs. This release does not provide a migration path from standard Luna partitions or Luna Cloud HSM services to keyrings. Thales requires minimum Luna Appliance Software 7.8.5 with the lnh_cluster-1.0.4 package, Luna HSM Firmware 7.8.4, and Luna HSM Client 10.7.2 to use clusters in production environments.


When the lnh_cluster package is installed, access to any existing partitions on the HSM is disabled, and this can only be reversed by re-imaging the Luna Network HSM 7 appliance (see Re-Imaging the Appliance to Baseline Software/Firmware Versions). Re-imaging is a destructive action; all roles, partitions, and keys are destroyed. The Luna Network HSM 7 must be completely reconfigured; all partitions must be recreated and their contents restored from backup. In particular, do not attempt to configure clustering on a Luna Network HSM 7 that already has V1 partitions created; either delete these partitions or re-image the appliance before configuring a cluster.

This release includes the following enhancements to the Clusters feature:

>Keyring Lockout Affects Current Session and New Sessions Only

When a keyring is locked out due to incorrect authentication, the keyring is locked out for that session and new sessions only. Existing sessions where authentication was correctly provided remain open and authorized.

Valid Update Paths

You can update the Luna HSM firmware to version 7.8.2 from the following previous versions:

>7.0.1, 7.0.2, 7.0.3, 7.1.0, 7.2.0, 7.3.0, 7.3.3, 7.4.0, 7.4.1, 7.4.2, 7.7.0, 7.7.1, 7.7.1-20, 7.7.2, 7.8.0, 7.8.1

Advisory Notes

This section highlights important issues you should be aware of before deploying HSM firmware 7.8.2.

FIPS Changes in Luna HSM Firmware 7.8.0 and Newer

The following mechanism is now restricted from use in FIPS mode:


FIPS Changes in Luna HSM Firmware 7.7.2 and Newer

The following mechanisms have new operation restrictions in FIPS mode:

>CKM_RSA_PKCS: cannot encrypt | Cannot legacy decrypt | Cannot legacy unwrap

>CKM_RSA_PKCS_OAEP: Cannot legacy decrypt | Cannot legacy unwrap

NOTE   This page lists FIPS-related changes made since the last FIPS-validated firmware release. For a comprehensive list of changes across all released versions of the Luna HSM firmware, see Changes to FIPS Mode Mechanisms and Operations by Firmware Version. Refer to this section if you are updating from a firmware version that is older than the last FIPS-validated version.

Minimum Password Length is Increased to 8 Characters

Luna HSM Firmware 7.7.2 and newer enforces minimum 8-character passwords and challenge secrets, to comply with FIPS requirements. The previous limit was 7 characters. If you were using a 7-character password prior to upgrading the firmware, that password continues to work. Future password changes will use the new 8-character minimum.

If you have an existing HA group whose member partitions use a 7-character password/challenge secret, you must change all members to use a minimum 8-character password before adding a new member that uses Luna HSM Firmware 7.7.2 or newer.

Partition policy to control the use of DigestKey is added

Partition capability/policy 9: Allow DigestKey is added with Luna HSM Firmware 7.8.0; it controls the possibility of final keys being derived outside of the HSM. The policy defaults to OFF, which is the more secure option. Previously, DigestKey was always allowed, and this new policy provides choice for those who do not need the option, as well as for those who do need it.

NOTE   Partition Policy 9 is destructive when switched OFF-to-ON, so have any partition contents backed up before you update HSM firmware. After update from any firmware prior to version 7.8.0, if you require this ability, you can switch the policy ON and then restore your material to the partition and resume using your application.

RSA Keygen Mechanism Remapping on Luna 7.7.1 or Newer Partitions Requires Minimum Luna HSM Client 10.4.0

Luna HSM Firmware 7.7.1 or newer partitions that have been individually set to FIPS mode using the new partition policy 43 require Luna HSM Client 10.4.0 or newer to automatically remap older RSA mechanisms as described in RSA Mechanism Remap for FIPS Compliance.

Special Considerations for Luna HSM Firmware 7.7.0 and Newer

Luna HSM Firmware 7.7.0 introduces new capabilities, features, and other significant changes that affect the operation of the HSM. Due to some of these changes, you must be aware of some special considerations before updating to Luna HSM Firmware 7.7.0 or newer. For more information, refer to Special Considerations for Luna HSM Firmware 7.7.0 and Newer before proceeding with the update.

3DES Usage Counter

For Luna HSM Firmware 7.7.0 and newer, triple-DES keys have a usage counter that limits each key instance to encrypting a maximum of 2^16 8-byte blocks of data when the HSM is in FIPS mode (HSM policy 12: Allow non-FIPS algorithms is set to 0). When the counter runs out for a key instance, that key instance can no longer be used for encryption or wrapping or deriving or signing, but can still be used for decrypting and unwrapping and verifying pre-existing objects.

The CKA_BYTES_REMAINING attribute is available when HSM policy 12: Allow non-FIPS algorithms is set to 0, but cannot be viewed if that policy is set to 1.

The attribute is preserved during backup/restore using a Luna Backup HSM 7; restoring puts the counter back to whatever value it had before backup.

The attribute is not preserved through backup/restore using a Luna Backup HSM G5; restoring sets the counter to like-new state (no usage).
