Luna HSM Firmware 7.8.0

Luna HSM Firmware 7.8.0 was released in July 2022. It includes bug fixes and updated FIPS 140-3 compliance requirements.

New Features and Enhancements

Luna HSM firmware 7.8.0 includes the following new features and enhancements:

Universal Cloning

Cloning (or migration) of keys and objects between Thales HSMs, has been enhanced as follows.

Updated encryption

Cloning encryption is now ECC-based (formerly RSA) and separates session-key negotiation from the use of session keys for migrating/transfering keys and objects within the security envelope with the following advantages:

>Consolidate HSM resources with secure and transparent exchanges of cryptographic material among mixed authentication modes:

multifactor quorum-authenticated and

password-authenticated partitions.

>Transfer keys to an entirely new domain, providing full interoperability between on-premises Luna Network HSM partitions and Luna Cloud HSM services.

Enhanced cipher suite options

Multiple cipher suites are available for cloning.

>Ciphers can be individually enabled or disabled by command.

>The protocol negotiates the strongest common suite enabled on source and target.

Multiple domains

Extended Domain Management widens the scope of key-migration/key-cloning operations, while maintaining the HSM security envelope.

>Up to three domains can be associated with a partition.

>Domains can be labeled for ease of management, and the labels can be changed for convenience.

>Password-authenticated cloning domains (text string) and multifactor quorum-authenticated domains (PED key secret) can be mixed on a single partition.

>Keys and objects can be shifted from one domain to another.

Session Key Lifetime Management

>Negotiated sessions have a finite lifetime (minimizing possibility of abuse), while being renegotiated with no burden to your applications.

>Multiple keys/objects can be transferred at one time, from one partition to another without requiring key-negotiation for each transfer (compare with prior behavior).

See Universal Cloning.

HSM SO Can Perform Time Management

The protocol (CPv4) behind universal cloning uses HSM time for session durations and other messaging. Time is also important in logging/auditing.
Time management functions formerly restricted to the Audit role are now available to the HSM SO, simplifying administration.

Clusters and Keyrings


Clusters and keyrings 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. This preview is currently available on password-authenticated Luna Network HSMs only.


When the 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 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 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 that already has V1 partitions created; either delete these partitions or re-image the appliance before configuring a cluster.

Luna Network HSM now allows you to store your cryptographic objects in an encrypted cluster within the appliance memory. This process uses Scalable Key Storage to encrypt the cluster and the SMK is shared with all member HSMs. The cluster contains keyrings, which are analogous to application partitions and can be accessed by a client in much the same way, by connecting to any member appliance. Keys are retrieved from the cluster, decrypted within the secure confines of the HSM, and used by the HSM for cryptographic operations. This configuration allows you to store many more keys than you can normally store within HSM partitions. The management of backup and restore operations is greatly simplified; the HSM administrator can back up the full content of a cluster, at scheduled intervals or on demand.

A cluster can consist of one Luna Network HSM member appliance, or multiple appliances that share the contents of the cluster. Adding multiple members to a cluster improves performance, and provides redundancy and failover for your client applications. Thales recommends a maximum of 4 members per cluster.

Up to 3000 keyrings can be created on the cluster, and each keyring can contain up to 256 objects.

This feature requires Luna Network HSM Appliance Software 7.8.0 or newer, Luna HSM Firmware 7.8.0 or newer, and each appliance in the cluster must have the cluster secure package installed. Luna HSM Client 10.5.0 or newer is required to access keyrings on a cluster. This feature is currently available on password-authenticated Luna Network HSMs only.

See About the Cluster Administration Guide.

Valid Update Paths

You can update the Luna HSM firmware to version 7.8.0 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, 7.7.2

Advisory Notes

This section highlights important issues you should be aware of before deploying HSM firmware 7.8.0.

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 140-3 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.

Luna Network HSM Appliance BIOS and BMC Firmware Update Patch is a Prerequisite

The Luna Network HSM Appliance BIOS and BMC Firmware Update Patch is a prerequisite for upgrading to Luna Network HSM Appliance Software 7.7.1 and newer. If your appliance was already at version 7.7.0, then the patch is already installed. If you are updating from an appliance version earlier than 7.7.0, then the patch must be installed before upgrading to 7.7.1 or newer.

CAUTION!   The Luna Network HSM Appliance BIOS and BMC Firmware Update Patch must be installed over SSH only. Installation over a serial port connection will fail.

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 Mechanism Remap for FIPS Compliance.

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.

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.

FIPS Restrictions in Luna HSM Firmware 7.7.0 and Newer

New restrictions have been added to some mechanisms when the HSM is in FIPS mode (HSM policy 12: Allow non-FIPS Algorithms set to OFF), to comply with FIPS SP800-131a Rev2 published in March 2019.

The following mechanisms are not permitted to wrap objects in FIPS mode (unwrap operations are permitted):










The following mechanisms are not permitted to sign data in FIPS mode (verify operations are permitted):
