Authentication Tests The following Authentication tests verify that the Mobile Station Under Test (MSUT) is able to use the Cellular Authentication and Voice Encryption (CAVE) algorithm correctly. For Authentication tests to pass, the MSUT and Test Set must possess identical sets of Shared Secret Data (SSD).
Chapter 6, Authentication Tests List of CDMA Authentication Tests List of CDMA Authentication Tests "Initializing SSD to Zero" on page 213 "Updating SSD" on page 222 "Performing a Unique Challenge-Response" on page 230 N:\mkt\MANUALS\HP8924C\APPMOD\BOOK\CHAPTERS\amauth.fb...
Chapter 6, Authentication Tests Initializing SSD to Zero Initializing SSD to Zero This procedure tests the MSUT’s ability to respond to a timer-based registration with authentication parameters that match the values expected by the Test Set. This procedure is performed after SSD has been initialized to zero in both the Test Set and MSUT.
Page 214
Chapter 6, Authentication Tests Initializing SSD to Zero 1. Register the MSUT. If the MSUT is already registered, this step is not necessary. if you are not familiar with how this procedure "Setting up a Call" on page 52 is performed with the Test Set. Registration provides the Test Set with the MSUT’s ESN (Electronic Serial Number).
Page 215
If the ESN changes (for instance when another MSUT is connected to the Test Set and registers) or is cleared, the Check Digits field will be cleared. If Kor PCS is selected in the Protocol field, the Check Digits field should be blank. HP-IB Syntax "CDMA:AUTH:AKEY ’0’" enters all zeroes in the A-Key field.

Chapter 6, Authentication Tests Initializing SSD to Zero 3. Initialize the MSUT’s SSD to zero. 1. Access the MSUT’s A-Key register and enter the identical sequence of digits displayed in the A-Key field, followed by the six Check Digits (if protocol is not Kor PCS). The MSUT should confirm the entry of a valid A-Key.
Page 217
2. Press the knob to select On. Selecting "On" in this field results in the Test Set signaling the MSUT to include authentication parameters in messages requiring authentication (AUTH_MODE =1). HP-IB Syntax "CDMA:CELL:CONF:AUTH:MODE ’ON’" turns authentication on. "CDMA:AUTH:DATA:CLE" clears the Authentication Data Table.
Page 218
AUTHR. This value is transmitted by the MSUT, then compared (along with other Authentication parameters) with the expected value by the Test Set to determine Pass/Fail status. HP-IB Syntax "CDMA:CELL:CONF:TREG:MODE ’ON’" turns timer-based registration on. "CDMA:AUTH:DATA?" queries the results displayed in the Authentication Data Table.

If you do not know the MSUT’s A-Key, and have no way of finding out what it is, try entering zero in the A-KEY field. The A-Key in many MSUT’s is initially programmed to zero until re-programmed by the service provider. HP-IB Syntax "CDMA:AUTH:AKEY ’0’" enters all zeroes in the A-Key field.
Page 225
2. Press the knob to select On. Turning Authentication "On" sets the AUTH_MODE bit to "01" in signaling messages and causes the MSUT to send Auth parameters AUTHR, RANDC, and COUNT to the Test Set.

Chapter 9, 264 Using the Analog Call Processing Subsystem Using the CALL CONTROL Screen to Test Call Processing Functions 7. Dial the desired phone number on the mobile station and press the SEND key on the mobile station’s handset. The mobile station signals the Test Set on the reverse control channel with an origination message which includes the dialed phone number, the mo- bile station’s MIN number and the mobile station’s ESN.
Chapter 9, 264 Using the Analog Call Processing Subsystem Using the CALL CONTROL Screen to test AMPS Authentication Using the CALL CONTROL Screen to test AMPS Authentication The process of testing AMPS authentication (IS-54) through the Call Processing Subsystem requires the user to synchronize the base station and mobile station. This synchronization requires that the base station and the mobile station possess two pieces of shared secret data (SSD) to confirm a valid call.

Page 326
1. To enable the interrupt in HP BASIC, the following command is executed: "ENABLE INTR 7;2" 2. After this command is executed, an SRQ from the Test Sets’ HP-IB interface will cause the application program to branch to the subprogram specified in the ON INTR command (see previous step).

To re-enable the SRQ interrupt after branching to the line in your code that services the interrupt: 1. Clear the Status Byte Register. Example: Status Byte = SPOLL (714). NOTE: The SPOLL command queries the Status Byte Register.
HP BASIC program was written for an HP 9000 Series 300 Controller and an HP 8924C. The program assumes that the HP 8924C is the only instrument on the bus. The program sets up an interrupt from the Standard Event Status Register Group, the Calibration Status Register Group, and the Hardware Status Register #1 Group.

Protocol Logging The CDMA protocol logging feature allows the capture of over-the-air forward and reverse IS-95A messages on the traffic channel or paging/access channel. This logging feature is intended to be used as a low-level tool to aid the advanced user in debugging new phone designs or qualifying the operation of new mobile stations.

Chapter 11, Protocol Logging Connecting the Test Set to the Computer Connecting the Test Set to the Computer CAUTION: Be sure that a null-modem cable connected to the Test Set is never left unterminated. It must remain connected to the computer’s serial port. Because data on the protocol logging connectors is transferred at a very high speed, an unterminated or poor quality null-modem cable could generate internal cross talk, causing the Test Set to behave erratically and possibly crash.
