PIN Pad 791 Programmer’s Manual (PCI POS-A) UDN PM0103-U Rev. 06

Section 1 – Introduction 2015-04-20

Section 1 Introduction

PIN Pad 791 (PP791) provides a secure and friendly way of obtaining customer Personal Identification

Numbers (PIN), dealing with smart card offline transaction specified in EMV Level 2 book 3 and book4.

PP791 can deal PIN entry and transaction in following ways:

1. As a PIN Entry Device (PED): PP791 can encrypt ANSI X9.8 standard PIN block by DES and TDES

algorithm, using master/session key or DUKPT as key management scheme. In addition, it can

encrypt EMV Level 2 specified PIN block by DES or RSA algorithm.

2. As an EMV Lv2 mini terminal: PP791 can handle most of the EMV Level 2 transaction flow,

especially card holder verification (CHV) process, and send transaction result to its host machine.

With properly development tool, system integrators can develop their customized application for

PP791, use its internal function calls to build their own transaction flow. PP791 will secure the

sensitive data by restricting the memory space that can be accessed by customized application

program.

PIN Pad components

This PIN Pad is composed of the following components:

(5) (6)

(1) (2)

(7)

(3) (4)

(1). LCD display with 320 * 240 resolution.

(2). Magnetic stripe reader swiping slot.

(3). 13 key telephone-style keypad and 3 function keys.

(4). Smart card reader inserting slot.

(5). Primary communication interface (RS232 or USB), with protection cover

(6). Ethernet LAN Port

Page11 Uniform Industrial Corp. Proprietary and Confidential Total 342 pages

PIN Pad 791 Programmer’s Manual (PCI POS-A) UDN PM0103-U Rev. 06

Section 1 – Introduction 2015-04-20

(7). Three secure access module (SAM) slots, with protection cover.

Display

The 320*240 pixels TFT LCD is capable of displaying characters and graphic. For displaying characters,

It provides ASCII 8*8 character set for range 0x20~0x7E, 8*16, 16*16, 16*24 character set for range

0x20~0xFF.

Keypad

The PIN Pad uses its 16 keys to accept commands. For each key pressed, there will be a short beep to

confirm that key is accepted. The following diagram shows layout of the keys.

1 2 3

4 5 6

7 8 9

CAN

CLR

[CAN] (Cancel) button will abort PIN entering transactions or magnetic card swiping actions, and cause

PP791 back to idle state.

[CLR] (Clear) button will reset PIN input when doing PIN entry transactions.

[F1] The F1 button is treated as “move up” when dealing with function menu (such as diagnostic

mode or EMV Lv2 transaction menu). With customized application, system integrators can define

its usage by themselves.

[F2] The F2 button is treated as “go back” when dealing with function menu. With customized

application, system integrators can define its usage by themselves.

ENTER

F1 F2 F3

[F3] The F3 button is treated as “move down” when dealing with function menu. With customized

application, system integrators can define its usage by themselves.

Communication Interface

PP791 has two communication interfaces:

1. A detachable 9-pin Mini-DIN interface which can be used to connect proprietary RS232/USB auto

selecting cable for power feeding and data exchange with host device.

2. A RJ-45 Ethernet jack for TCP/IP communication.

Magnetic and Smart Card reader

The smart card reader of PP791 can accept EMV Level 2 compatible smart cards for offline transaction,

PIN Pad 791 Programmer’s Manual (PCI POS-A) UDN PM0103-U Rev. 06

Section 1 – Introduction 2015-04-20

or exchange APDU packets with EMV Level 1 compatible smart cards via ICC-related commands. It also

reads ISO 7811 compatible magnetic cards for legacy online debit / credit card operation.

Smart card and Security Access Module (SAM) interfaces

PP791 provides three SAM interfaces (optional) for customer usage. System Integrators can use PP791

internal API or SAM-related commands to switch between different slots and exchange APDU.

Tamper Evidence and Tamper Responsive

PP791 is compatible with “Payment Card Industry (PCI) POS PIN entry device security requirement”

version 3.0. Per this requirement, PP791 will detect tampering attempts by its multiple security design. If

tamper is detected, security subsystem will cause the automatic and immediate erasure of all secret

information contained in it. Such as master keys, DUKPT key, personalization information and so on.

Without security information PP791 will not work anymore. A user should contact system

integrator or vendor representative for RMA when a PP791 was tampered.

Section 2 –System Manager 2015-04-20

Section 2 System Manager

Introduction

The system manager is a resident process launched automatically when PP791 boot up. It will manage

the download and execution of other application, do basic settings, and self tests.

After system booted up and the startup application is launched, user can press “ENT + 1” (press ENT

key and ‘1’ at the same time), then input dual passwords of system manager to enter system manager

menu. (The default password will be sent to legal user by secure method).

NOTE 1: Enter system manager will terminate the current application.

NOTE 2: System manager will exit and re-launch startup application if no input over 60 seconds.

Security management

1. Personalization and tamper detection

Each PP791 is “personalized” (create an AES key randomly for sensitive data protection) before

delivery. Every time PP791 boot up, system manager will check the personalization status and

existence of this AES key. If device is tampered, security mechanism will erase the AES key and

invalid personalization status, then reboot. After reboot, system manager will see the change and

show following message (tamper evidence mode):

“System has tampered, you shall release it before you can normally use.”

In this situation, user can press “ENT + 1” (press ENT key and ‘1’ at the same time), then input

dual passwords of system manager to exit tamper evidence mode.

When exiting tamper evidence mode, PP791 will be re-personalized. All keys will be erased.

2. Certificate management

Every application in the PP791 should have digital signature (sha256 hash encrypted by 2048bit

RSA key) The system process (system manager and PP791 appl.,) will be verified by a fixed

system certificate resident in system kernel, and user applications will be verified by user-loaded

certificates, which is managed by system manager.

The certificate hierarchy of PP791 contains:

Vendor certificate: This certificate is created by user (i.e. system integrator or bank), it verifies user

applications when downloading application and launching application.

Intermediate certificate: This certificate is issued by intermediate CA, it verifies vendor certificate

every time when system manager starts.

Root certificate: This certificate is issued by root CA, by default, PP791 have a root certificate

resident in system kernel. But users can load their own root certificate along with intermediate and

vendor certificate in the same trust chain. It verifies intermediate certificate every time when

system manager starts.

Prepare downloading

User has to use system manager to download applications, graphics, or update system components.

There are two methods to download: via TCP/IP (need to a FTP server, and correctly setup IP address

and FTP config scripts by “Setting” menu).

Prepare FTP server:

User can establish a FTP server on any computer that already connected to LAN and have valid IP

address. The server should have a directory (i.e. ftproot/pub) that contains following directory (case

sensitive):

1. certs: Contains certificate files with pre-defined names: “appl_vendor.crt” for vendor

certificate; “appl_inter.crt” for intermediate certificate; “custom_root.crt” for customized

root certificate if needed; “certificates.tar.gz” for package download if needed.

2. graphics: Contains a “graphics.lst” file and picture packages in tar.gz format.

3. system: Contains system update files provided by UIC.

The list files (graphics.lst) are pure text file, with one name per line:

Graph_01

Graph_02

.....

When PP791 reads “Graph_01”, in graphics.lst, it will go to server to find “Graph_01.tar.gz”.

Prepare FTP config script:

PP791 can manage multiple FTP settings by selecting config script. Each config script should have the

extension name “.cfg”, with following format:

host=xxx.xxx.xxx.xxx

port=21

user=anonymous

Page15 Uniform Industrial Corp. Proprietary and Confidential Total 342 pages

IP address of FTP server.

FTP port number.

PP791 will read an “ftp_setting_file” which contains one ftp config script name, and use it as

default FTP setting. The factory default of ftp_setting_file is:

ftp_site1.cfg

(As a result, system manager will read server IP address, port, username and password from this file).

The FTP setting file and config scripts can by edited by system manager.

Section 4 – Message format 2015-04-20

Section 4 Message format

This chapter details the format of messages exchanged between the host and PIN Pad.

Notation Conventions

The following conventions are used to make the description of messages more readable:

Control Codes

Control codes (non-displayable codes) are represented by two to three capital letters enclosed in angled

brackets “<>“. This PIN Pad uses 12 control codes in total. Their actual code, when referenced, is

represented by two hex digits enclosed in angled brackets, <0F> for example. The following table lists

their usage and value in hex codes.

CODE HEX VALUE USAGE

STX 02 Denotes the beginning of a message frame

ETX 03 Denotes the ending of a message frame

EOT 04 Indicates communication session terminated

ACK 06 Acknowledge of message received

SI 0F Denotes the beginning of a message frame

SO 0E Denotes the ending of a message frame

NAK 15 Indicates invalid message received

SUB 1A Message parameter follows

FS 1C Field separator

GS 1D Message ID follows

DC1 11 Used for Z2 message, enable inverse mode.

DC2 12 Used for Z2 message, disable inverse mode.

[LRC]

Each message frame transmitted is followed by an LRC byte to detect communication error. This byte

should be regarded as part of the message frame but comes after the ending delimiter character. [LRC]

is used to represents this LRC byte in describing message frames.

LRC is calculated as an XORed value of every byte after start code in the message frame except itself,

that means from the next byte of <STX> or <SI> through the <ETX> or <SO> byte.

[item]

A descriptive item name enclosed in bracket denotes a string or data byte that has no fixed value.

Page26 Uniform Industrial Corp. Proprietary and Confidential Total 342 pages

PIN Pad 791 Programmer’s Manual (PCI POS-A) UDN PM0103-U Rev. 06

Section 4 – Message format 2015-04-20

Message frame summary

Data exchanged between PIN Pad and host computer are grouped into “message frames”. Each

message frame has one of the two frame formats listed below:

 <STX>[message ID][data]<ETX>[LRC]

 <SI>[message ID][data]<SO>[LRC]

Each type of message has a unique value in its message ID field. In the following texts, we reference a

message type by its message ID value, e.g. “message 70”.

Message type

Messages exchanged between the PIN Pad and the HOST can be divided into two categories.

One is for administration and maintenance, in general administrative messages have <SI> packet

header and will return message to HOST by the same message ID.

The other is for various transactions, in general transaction messages have <STX> packet header, and

comes in pair. Even number message packets sends command and data to PIN pad, then odd number

message packets returns the result.

Time-out

Whenever the PIN Pad sends a message, a response (<ACK> character for acknowledgement or

<NAK> character if LRC error occurred) from host is expected. If the PIN Pad does not receive a

response within 5 seconds, it will retransmit the last packet. If PIN pad does not receive <ACK> or

<NAK> after two retransmit attempts, it will send <EOT> character and this communication session will

be terminated.

Transmission Error

The PIN Pad expects the host computer to send a NAK when the host decides that an invalid frame is

received. When the PIN Pad receives a NAK, it will retransmit its last message. If the message

retransmitted is invalid again, then a NAK should be sent by host to request for another try. The PIN Pad

will keep on retransmitting until an <ACK> or <EOT> is received.

Packet Error

When PIN pad received a good transmission but invalid packet (wrong message id) it will ignore the

packet. If the packet has acceptable message id but have wrong format. PIN pad will send <EOT> as

error message. When in PIN entry functions it will send more detail error code.

Message length: Variable (38 to 94 bytes).

Usage: Load Master Keys into PP791.

PP791 can store 32 master keys (16 of them not used by PP791 application); each has

a one digit ID. Master keys are divided into three groups of different functions. Refer to

Appendix A: Key management for key usage and ID definition.

PP791 implements multiple security measures to conform Payment Card Industry (PCI)

security requirement. In order to load clear text master keys, two authorized people

with their password are required. Otherwise the user must issue message 02 with

encrypted key value (ANSI TR31 format). See next entity “Symmetric Keys Loading

Authentication” for detailed information.

Note: 1. The [key value] field’s format is ASCII string with range ‘0’-‘9’, ‘A’-‘V’, which

represents a hexadecimal byte in two characters, i.e. “1F” represents 0x1F.

2. PP791 requires key loading key (master key #F) to be TDES.

3. Pass key loading authentication and then load new clear text master key will erase

all other master keys, to prevent malicious key substitution. For more information refer

to “Symmetric Keys Loading Authentication” at page 24.
