Discussion on clinical safety

The AN/PRC-150(C) holds 25 TEKs, one Key Encryption Key (KEK), and one Transfer KEK (TrKEK) for each COMSEC type of either VINSON, ANDVT or KG-84. Numbering for each storage set is from 01 to 25. Table 3-6 shows a sample chart that may be used for key management. The following procedures describe how to load COMSEC fill data of either TEKs for VINSON, ANDVT, or KG-84 COMSEC.

*Each slot can be used for either ANDVT-HF or ANDVT-BD.

**Each slot can be used for either KG84-R or KG-84-NR.

3.8.1 Load COMSEC Fill Data of TEK or KEK with AN/CYZ-10 Using RDS Perform the following procedure to load COMSEC Fill data with AN/CYZ-10 (ANCD):

NOTE

AN/CYZ-10 menus vary from device to device. The instructions here may not exactly match your device.

a. Rotate radio front panel function switch to LD.

b. Select KYK-13, then press [ENT].

c. Select the desired CRYPTO TYPE of either VINSON, ANDVT or KG-84, and press [ENT].

d. Select the appropriate KEY TYPE. If TEK is selected, select the key position number (01 - 25), and press [ENT]. PRESS ENT TO INITIATE displays.

NOTE

Leave the radio at the PRESS ENT TO INITIATE screen for now.

e. At AN/CYZ-10, choose APPL>RDS>RADIO>COMSEC>LD, then press [ENTR].

f. Choose either TEK or KEK, and press [ENTR].

g. Use [P UP] and [P DN] until desired key appears, then press [ENTR]. XMT appears in lower right of screen.

h. Select qUit. and press [ENTR]. Connect ANCD to RT appears.

i. Connect AN/CYZ-10 to the J18 FILL connector.

j. Press on AN/CYZ-10. A message appears that the AN/CYZ-10 is sending a key, followed by Press [LOAD] on RT.

k. At radio, press [ENT]. IN PROCESS, followed by FILL DONE PRESS ENT should appear.

l. Press [ENT]. MORE FILL DATA?, will appear.

m. At prompt MORE FILL DATA?, select YES to enter more fill data. Otherwise, proceed to Step o.

n. To load more keys of the same crypto type, repeat Step d through Step k.

o. To load more keys of a different crypto type, press [CLR] and repeat Step c through Step k.

p. When all fill data is entered, select NO when the MORE FILL DATA? prompt displays.

q. Turn off AN/CYZ-10 and disconnect from the radio J18 FILL connector.

r. Rotate function switch from LD to desired operating position (PT, CC, CT, or Receive Variable [RV]).

3.8.2 Load COMSEC Fill Data of TEK or KEK with KYK-13, KYX-15, KOI-18

Perform the following procedure to load COMSEC Fill data with KYK-13, KYK-15, or KOI-18 fill devices:

a. Turn fill device off.

b. Connect fill device to the J18 FILL connector.

c. Turn fill device on and select key position on fill device. (If using KOI-18, have key tape ready to pull.) d. Rotate radio front panel function switch to LD.

e. Select appropriate fill device then press [ENT].

f. Select the desired CRYPTO TYPE of either VINSON, ANDVT or KG-84, and press [ENT].

g. Select the appropriate KEY TYPE. If TEK is selected, select the key position number (01 - 25).

h. PRESS ENT TO INITIATE displays, and press [ENT].

i. IN PROGRESS displays. If using KOI-18, pull tape now.

j. When FILL DONE PRESS ENT displays, press [ENT].

k. At prompt MORE FILL DATA?, select YES to enter more fill data. Otherwise, proceed to Step n.

l. To load more keys of the same crypto type, repeat Step g through Step k.

m. To load more keys of a different crypto type, press [CLR] and repeat Step f through Step k.

n. When all fill data is entered, select NO when the MORE FILL DATA? prompt displays.

o. Turn off fill device and disconnect from J18 FILL connector.

p. Rotate function switch from LD to desired operating position (PT, CC, CT, or Receive Variable [RV]).

3.8.3 Loading COMSEC Fill Data of TEK, KEK, or TrKEK with AN/CYZ-10 Data Transfer Device (DTD) using FILL Application

An AN/CYZ-10 using DTD FILL program should be set to DS-101 protocol. Perform the following procedure:

NOTE

Ensure DTD FILL program is set to DS-101 protocol before beginning. In the DTD loading process, always select ISSUE as transmit mode. If FILL transmit mode is used, it will result in a BAD FILL.

NOTE

AN/CYZ-10 menus vary from device to device. The instructions here may not exactly match your device.

a. Turn AN/CYZ-10 DTD fill device on. Use DTD FILL program to initiate loading of required key.

b. Connect fill device to J18 FILL connector when directed by the DTD menu instructions. Select the key to be loaded and use ISSUE as the transmit mode. Stop at the DTD when it displays to press SEND.

c. Rotate function switch to LD.

d. Select DS101 as the fill device and press [ENT].

e. Select the KEY TYPE, then select the key compartment position number (01 - 25). Press [ENT].

NOTE

KEKs and TrKEKs do not require a compartment number.

f. INITIATE FILL AT FILL DEVICE displays.

g. Press SEND on the DTD. The radio displays FILL IN PROGRESS.

h. When FILL DONE displays, press [ENT].

i. At prompt MORE FILL DATA?, select YES to enter more fill data. Repeat Step e through Step i. Use DTD menu to back up for new key selection.

j. When all fill data is entered, select NO when the MORE FILL DATA? prompt displays.

k. Turn off DTD and disconnect it from the J18 FILL connector.

l. Rotate function switch from LD to desired operating position (PT, CC, CT, or RV).
