KEY LIST OF ARMY VIOIATIONS 

Apr. , May, June, 1954 

ROTOR ARRANGEMENT 

1, Use of a rotor arrangement for an inappropriate cryptoperiod, day 

or month. (Reference AFSAG 1262, para 5006a(l)) 

2, Use of a rotor arrangement from a key list assigned to another 

station. (Reference AFSAG 1262, para 5003b) 

ROTOR ALIGNMENTS, 

3. Discrepancy between the message rotor alignment resulting from 

decipherment of th~ message indicator and the message rotor alignment actually required to decipher the message, although the latter 

was correctly derived. The discrepancy involves (a) transposition 

or letters, (b) substitution of a letter alphabetically adjacent to 

the correct letter, (c) substitution of a phonetically similar letter, 

or (d) errors in encipherment. 

4. Identical message indicators appeared on different messages (or transmission sections) enciphered on the same machine. Use of the 

message rotor alignment resulting from decipherment of the message 

indicator allowed decipherment of the first but not the second 

message. The message rotor alignment actually used for encipherment 

of the second message was properly tailed to the final alignment of 

the first message. 

5. The message rotor alignment actually used for encipherment was identical to the final alignment of the previous message enciphered on 

the same machine. However, the last five letters of the message 

indicator decipher to a properly tailed alignment. (Reference AFSAG 

1262, para 6002a(4)) 

6. Failure to tail previously enciphered message. (Reference AFSAG 

1262, para 6002a(4)) 

7. Decipherment of the message indicator resulted in a message rotor 

alignment identical to the final alignment of the previous message 

enciphered on. the same machine. The message rotor alignment actually 

used for encipherment, however, was correctly derived. 

8. Omission or addition of one or more letters to the message indicator. 

KEY GROUP 

9. The trigraphic key-group indicator in the message indicator did not 

correspond to the key group actually used for encipherm.ent. Reuse 

.Pf a key group was not involved. (Reference AFSAG 1262, para 5004b) 

Incl 2 SECRE'fRYPTOCLEARANCE REQUmED 
. . .. ... · - SESH'i!.W 

MACHINE DESIGNATOR AND MULTISWITCH SE'ITING 

10. The machine designator in the message ~ndicator did not correspond 

to the multiswitch setting used for encipherment. The messages 

were (a) correctly enciphered or (b) incorrectly enciphered. (Re~erence AFSAG 1262, pa.ra 6002a(l)) 

ENClPHER DEClPHER CARD 

11. Incorrect use of an ORCUS enciphering card to produce a message 

indicator. (Reference AFSAG 1262, para 5005c) 

ADDITIONAL VIOIATIONS 

12. Transmission in the clear of classified information. 

13. Transmission of classified in:f"orma.tion in monoalphabetic substitution cipher. 

14. Transmission of a message in which there was faulty rotor stepping 

during encipherment. (Reference AFSAG 1262, para 6002a(3))
