Introduction

Read this guide if …​

Read this guide if you need to configure or manage:

  • An Entrust Hardware Security Module (HSM).

  • An associated Security World. nShield hardware security modules use the Security World paradigm to provide a secure environment for all your HSM and key management operations.

The nShield HSM is connected to a network by an Ethernet connection. Each HSM is configured to communicate with one or more client computers on the network. You can also configure clients to make use of any other network-connected HSMs on the network, as well as locally connected HSMs.

All nShield HSMs support standard cryptography frameworks and integrate with many standards based products.

This guide assumes that:

  • You are familiar with the basic concepts of cryptography and Public Key Infrastructure (PKI)

  • You have read the Installation Guide.

  • You have installed your nShield HSM.

Throughout this guide, the term Installation Guide refers to the particular Installation Guide for your product.

Security World Software

The Security World for nShield is a collection of programs and utilities, including the hardserver, supplied by Entrust to install and maintain your nShield security system.

Entrust provides the firmware that runs on the nShield HSM, and software to run on each client computer. The nShield HSM is supplied with the latest version of the HSM firmware installed. For more information about:

Software architecture

The software, firmware, and utilities have version numbers and there is also a version number for the World which refers to the World data that is stored in encrypted form on the client computer, typically in the NFAST_KMDATA directory or on the RFS. This data includes information concerning the World itself and also concerning each key that was created within that World. The World version created is determined by the version numbers of the software and firmware used when it was first created, see Creating and managing a Security World.

The latest World version is version 3. You can query the version of the World loaded on your system by using the command kmfile-dump.

Hardserver

The hardserver software controls communication between the internal security module and applications on the network.

Separate instances of the hardserver run on the unit and each client that is configured to work with the unit. There is a secure channel, known as the impath, between the two software instances, which forms a single secure entity for transferring data between the unit and the clients. See also Compatibility issues.

The unit’s hardserver is configured using the front panel on the unit, or by means of uploaded configuration data. Configuration data is stored on the unit and in files in a specially configured file system on each client computer. For more information about using:

Remote file system (RFS)

Each unit uses a remote file system (RFS). You can configure the RFS on any computer, but it is normally located on the first client that is configured. The RFS contains:

  • The master configuration information for the unit

  • The Security World files

  • The key data.

Do not copy the master configuration to file systems on other clients. You can copy Security World files and key data to other clients to allow you to manage the unit from more than one client. To make it available to the unit, copy to the RFS the data for Security Worlds, cards or keys that you create on a client that does not contain the RFS.

Security World Software

The Security World Software is a collection of programs and utilities that you install on the client and use to maintain the nShield security system. The Security World Software includes the following:

  • The appropriate installer for the client platform

  • The client hardserver

  • A set of utilities for configuring the nShield HSM

  • A set of utilities and the KeySafe application for performing key management tasks on nShield HSMs.

The nShield HSM is referenced and used by a utility or application in the same way as a local (PCI-connected) nShield HSM.

Default directories

The default locations for Security World Software and program data directories on English-language systems are summarized in the following table:

Dynamic feature certificates must be stored in the directory stated above. The directory shown for static feature certificates is an example location. You can store those certificates in any directory and provide the appropriate path when using the Feature Enable Tool. However, you must not store static feature certificates in the dynamic features certificates directory.

The instructions in this guide refer to the locations of the software installation and program data directories by their names (for example, Key Management Data) or

Utility help options

Unless noted, all the executable utilities provided in the bin subdirectory of your nShield installation have the following standard help options:

  • -h|--help displays help for the utility

  • -v|--version displays the version number of the utility

  • -u|--usage displays a brief usage summary for the utility.

Setting the PATH for nShield utilities

It is recommended that the PATH environment variable be changed to include

This is the directory in the nShield installation that contains the nShield command-line utilities and some DLLs.

This will allow all the nShield command-line utilities to be run without the need to type the full path, for example running enquiry instead of

must be set in the PATH in order to use the OpenSSL module in the Python that is bundled with nShield.

The Python bundled with nShield is located in a separate directory, If using the nShield Python, you may additionally want to add this directory to the PATH environment variable so that you can run the nShield python as just the python command. You may not want to do this if you are also using other Python installations on the same machine.

Further information

This guide forms one part of the information and support provided by Entrust.

If you have installed the Java Developer component, the Java Generic Stub classes, nCipherKM JCA/JCE provider classes, and Java Key Management classes are supplied with HTML documentation in standard Javadoc format, which is installed in the appropriate directory when you install these classes.

Security advisories

If Entrust becomes aware of a security issue affecting nShield HSMs, Entrust will publish a security advisory to customers. The security advisory will describe the issue and provide recommended actions. In some circumstances the advisory may recommend you upgrade the nShield firmware and or image file. In this situation you will need to re-present a quorum of administrator smart cards to the HSM to reload a Security World. As such, deployment and maintenance of your HSMs should consider the procedures and actions required to upgrade devices in the field.

The Remote Administration feature supports remote firmware upgrade of nShield HSMs, and remote ACS card presentation.

We recommend that you monitor the Announcements & Security Notices section on Entrust nShield, https://nshieldsupport.entrust.com, where any announcement of nShield Security Advisories will be made.
