CHAPTER 1

Introduction

This document describes instructions, policies and procedures, for integrators of Invenco Group’s security products into larger systems (e.g. into payment terminals for petrol station forecourts). Its security classiﬁcation reﬂects that it is available only to parties approved by Invenco; anyone in possession of it is responsible for maintaining conﬁdentiality of the manual itself and all information contained herein.

1.1 Important Related Documents

Invenco’s security products manage sensitive information. Accordingly the company imposes certain strictures which apply even while Invenco does not have custody of its products. These strictures must be adhered to by integrators (and their agents such as service technicians – Invenco makes no distinction for the purpose of responsibility). They are compiled separately into [G7INTSEC] which is available publicly; they are not the focus of this document.

Similarly this document is not a developer manual: it does not duplicate information essential to programmers writing software to work with Invenco’s products. Software development is a challenging task for integrators; Invenco provides extensive support for it. Integrators should approach the company for resources and assistance.

1.2 Important Information on Radio Frequency Components

CHAPTER 2

Shipment Veriﬁcation

2.1 Introduction

This chapter provides a guide to the security veriﬁcation of the G7OPT/SDC/UPC on receipt.

It is necessary that, before the units are deployed, their integrity is veriﬁed and there is no evidence of them having been compromised or altered during shipping.

It is also essential that full asset-tracking of units takes place during shipping, to ensure early identiﬁcation of stolen units.

Finally it must be veriﬁed that the version of each unit is as expected and as required for deployment.

The processes described outline the veriﬁcation steps that should be taken, and the appropriate escalation process to follow when relevant.

G7OPT Integrator Manual, DWI-00175 S1 R15

2.2 Shipment Checks

Unpacking and package-checking of the shipment must include the following checks as a minimum:

• validation of correct delivery

• validation of bulk packing is intact

• validation of correct quantity and serial numbers

• validation of individual box tamper-seals.

2.2.1 Bulk Packaging Check

Before the individual items are removed from the bulk package, the bulk package must be inspected for damage or tampering. If evidence of damage or tampering is found, the following steps should be taken:

• take photographic evidence of the damage/tampering

• raise an exception report including the photographic evidence; see §2.5.2 Exception Escalation.

2.2.2 Serial-number Check

It is important not only that quantities are validated but also that the serial numbers of the expected items correspond to the packing-slip.

Each box must contain the serial number of the enclosed product, which must be checked off against the packing-slip.

Should the contents of an individual box not be validated as correct at this stage, a check for the correct serial number must be performed at the time of opening the box.

Should a serial number be missing or unrecorded on the packing-slip an exception must be raised as deﬁned in §2.5.2 Exception Escalation.

2.2.3 Individual Box Checks

Ensuring the packaging of the individual item is intact is essential and must be performed on all items received.

The following process is to be used to ensure each item has been received with integrity intact:

• check that the tamper-seals (top and bottom), as shown in picture below, are correct by inspecting them for the following signs of tampering:

– the seal is as per the image below

– the seal does not show the words VOID

– the seal has not been cut

– there are not multiple seals overlaid

– the seal has not been covered by clear tape

– there is only one seal on the top and bottom of the box

• check that the packaging has not been opened or cut in any way

• check that the box is not damaged.

2.3 Integrity Veriﬁcation

Ensuring that the unit is secure and has not been tampered must be performed at staging before the device is deployed to site.

If the device is found to be in a compromised state the escalation process below must be followed.

To check the integrity of the unit the following two processes must be followed:

2.3.1 Initial Power-on Check

When the unit is powered on, it determines whether an exception occurred during its power-on self-test or any tampers were triggered while it was powered down. In either case the device will place itself in a restricted mode, with distinctive indications given according to whether it was Destructive Secure Reset or removal-tampered.

2.3.1.1 Tamper Indications

A DSR is a dramatic response to what a unit interprets as an integrity violation: the device shuts down instantly, wiping its security keys and other sensitive information. The device is not ruined but it is “bricked”: it cannot operate in any capacity and can be disassembled, repaired and reinitialized only by Invenco – a return-to-base procedure. Returning a destructive-tampered unit to Invenco requires an auditable process with formal changes of custody, probably including packaging, transport and staging.

The G7SDC will display a “DT event” screen; the G7UPC will display a fast (twice a second) red keypad LED indication:

Fig. 2.3: SDC Destructive Tamper (DT) event screen

In contrast, the removal tamper response is intentionally less drastic. Removal tamper sensors protect a unit that is intact: it may have been removed – even maliciously – from a system in which it was integrated, but the unit’s integrity has not been violated and it is still operational (albeit in a restricted mode). Signiﬁcantly its cryptographic keys have not been erased, although it remains incapable of ﬁnancial transactions until restored to normal operation from the removal-tampered state. If necessary the unit can still perform a DSR.

The G7SDC will display a “RT event” screen; the G7UPC will display a slow (once a second) red keypad LED indication:

Chapter 2. Shipment Veriﬁcation 6

G7OPT Integrator Manual, DWI-00175 S1 R15

Fig. 2.4: SDC Removal Tamper (RT) event screen

If this occurs, follow the exception escalation process deﬁned in §2.5.2 Exception Escalation.

2.3.2 Hardware Certiﬁcation Status

The second test – assuming the device has booted successfully – is to check that its certiﬁcates are loaded and intact.

This test requires the use of TMSlite to query the key-store status using the following steps:

1. Connect the terminal to the workstation that is running TMSlite, with an intermediate protocol converter such as Invenco’s external application-software controller.

2. (First time only) Click Add, enter the terminal connection details, then click OK.

3. Select the terminal from the left-hand list, click Connect, then select “UPC” from the ﬁlter dropdown list.

4. Scroll down the list and make sure the properties upc.certificate.housekeeping and upc.certificate.module are present and not empty. If either property is missing, follow the exception escalation process deﬁned in §2.5.2 Exception Escalation.

5. Repeat for the SDC by selecting “SDC” from the ﬁlter drop-down list, and make sure the properties sdc.certificate.housekeeping and sdc.certificate.module are present and non-empty.

Chapter 2. Shipment Veriﬁcation 8

G7OPT Integrator Manual, DWI-00175 S1 R15

2.4 Version Veriﬁcation

Before a unit is deployed into a production environment, version information should be validated to ensure it is correct.

Use the following process to verify the hardware certiﬁcation revision and software version information.

2.4.1 Hardware Certiﬁcation Revision

Ideally, a hardware certiﬁcation revision number check can be done at the same time as verifying the serial number.

On the back of each unit is a product information sticker which contains, amongst other information, a serial number and the hardware certiﬁcation revision number.

Inspect this sticker and conﬁrm the certiﬁcation revision is correct.

Note: The red content in the above images is for illustrative purposes for this document and must not

exist on actual product labels.

2.4.2 Software Version Numbers

To obtain the core security modules’ version information, the terminal management interface will need to be interrogated.

Using TMSlite or an in-house proprietary terminal management tool, retrieve the version information and validate the information tags below.

Note: The paramount ﬁrmware-versions have the tags "upc.root.ver" and "sdc.root.ver" for their respective devices. These versions are controlled by the build system which ensures that all ﬁrmware components – including the Boot Monitor, Root Filesystem and Tamper Monitor – are built and versioned at the same time.

2.5 Communications

2.5.1 Receipt Veriﬁcation

Invenco requests conﬁrmation that the shipment has been received in full. This should be sent to orders@invenco.com.

This communication must conﬁrm the following:

• Expected quantity has been received.

• All packages/boxes are in good order and security seals intact.

• All serial numbers are accounted for.

2.5.2 Exception Escalation

Should any of the checks detailed in §2.2 Shipment Checks identify that the delivery has been compromised, or if the checks detailed in §2.3 Integrity Veriﬁcation and §2.4 Version Veriﬁcation are not correct, the following escalation process must be followed:

• Send an email to orders@invenco.com detailing the exception, including all the evidence outlined in the veriﬁcation processes above.

• If possible, follow through with a phone call to Invenco using the contact details provided on the contact page of the Invenco website: http://www.invenco.com/contact

• Notify the shipping/courier of this exception if applicable.

CHAPTER 3

Tampers

3.1 Background – Tamper Types

Many Invenco products support two types of tamper protection; in increasing order of security they are:

• removal tamper

• destructive tamper, also known as “Destructive Secure Reset” (DSR).

3.1.1 Tamper Indications

The G7SDC will display a “DT event” screen; the G7UPC will display a fast (twice a second) red keypad LED indication:

Fig. 3.1: SDC Destructive Tamper (DT) event screen

DWI-00175 S1 R15 13

G7OPT Integrator Manual, DWI-00175 S1 R15

The G7SDC will display a “RT event” screen; the G7UPC will display a slow (once a second) red keypad LED indication:

Fig. 3.2: SDC Removal Tamper (RT) event screen

3.2 Removal Tampers

Removal tampers are designed with integrators and their agents in mind; they maintain ﬁnancial security while allowing legitimate operations, such as installation or swap-out by service staff. While in the removal-tamper state, the following operations are possible using TMSlite:

• clearing removal tampers

• installing packages

• retrieving logs

The following sections describe the steps for:

• connecting an Invenco product to external tamper sensors that will protect it within an integrated system

• clearing the removal-tamper state and promoting the unit to normal operation.

The reverse steps, for removing a unit, need no explanation; they should be straightforward and largely mechanical. In contrast with installing a device and clearing its removal-tampered state, cryptographic authentication is unnecessary. The main security considerations when removing a unit are to avoid an accidental DSR in the process and not to lose it afterwards.

Note: It is strongly recommended to retrieve all logs before unit removal, for problem-solving and root-cause analysis.

Chapter 3. Tampers 14

G7OPT Integrator Manual, DWI-00175 S1 R15

3.2.1 Installation with Removal-Tamper Sensors

1. Obtain access to where the unit will be integrated into its system, paying attention to authorisation by accredited staff.

2. Obtain custody of the unit and any documentation, cables and other ancillary products.

Adhere to the requirements for custody change, unpacking, etc. in [G7INTSEC] as appropriate.

3. Mount the unit, and others which it will be connected to, in accordance with the integrator’s instructions and those of Invenco.

See §5.1 G7SDC Installation Guide or §5.2 G7UPC Installation Guide for details. If instructions conﬂict, Invenco’s must take precedence; failure to observe this may compromise the unit’s security and/or void its standards certiﬁcation.

4. Connect the unit to all others that it is being integrated with.

Tamper connections will vary according to whether the Invenco unit is integrated standalone or in an Invenco housing. Both methods are described in the appended installation guides. Removal tampers are likely to have been connected already in the course of mounting the unit; additional connections for tampers should be unnecessary.

3.2.2 Removal-Tamper Clearing and Promotion to Normal Operation

1. The unit is now integrated into the system; it is in the removal-tampered state. Power it up and verify that restricted-mode operation is possible.

In removal tampered state:

• the UPC will display a slow (once a second) red ﬂashing LED

• the SDC will display a “removal tamper” error message

2. To clear the removal-tampered state and enable the unit for normal operation requires a cryptographically authenticated challenge and response between it and an authorisation device. This transaction is performed under dual control, the two parties being a ﬁeld engineer and a control-centre operator.

(a) The ﬁeld engineer must ﬁrst request a challenge token from the integrated unit. This is

achieved by:

i. Connect the terminal to the workstation running TMSlite.

ii. (First time only) Click Add, enter the terminal connection details, then click OK.

Fig. 3.3: Terminal connection details.

iii. Select the terminal from the left-hand list, then click Connect.

v. Choosing either “UPC Tamper Clear” or “SDC Tamper Clear” from the dialog box drop-

down menu.

Fig. 3.5: TMSlite “Tamper Clear” dialog box

vi. Clicking “Challenge” to display the required challenge token.

(b) Next, the ﬁeld engineer must log in to the control centre and post the token and the device’s

serial number into an installation authorisation request.

generate an authorisation token and return it to the ﬁeld engineer.

(d) The ﬁeld engineer submits the authorisation token to the device by keying it in manually and

clicking “Apply”.

Note:

• The display unit (SDU/SDC) and keypad (UPC) must be connected together throughout this process.

• The challenge / response operation must be completed within 30 minutes; if not, a new challenge token must be generated and the process repeated.

The unit itself is now in normal mode and ready for operation. Devices that it is integrated with may require additional steps; consult product manuals.

3.3 Retrieving logs and exporting parameters

It is strongly recommended to retrieve all logs before unit removal, for problem-solving and root-cause analysis.

1. Select menu item Tools > Retrieve Logs:

Fig. 3.6: Menu item Tools > Retrieve Logs

2. Select the desired subsystem (e.g. UPC) and the number of log ﬁles to retrieve, then click OK.
