KEY LIST OF AIR FORCE VIOLATIONS 

Oct., Nov., & Dec.,•1954 

ROTOR ARRANGEMENT 

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

or month. (Reference AFSAG 1262, para 5oo6a(l)) 

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

station. (Reference AFSAG 1262, para 5003b) 

3. Use for encipherment of superseded rotors. 

ROTOR ALIGNMENT AND MESSAGE INDICATOR 

4. Discrepancy between the message rotor alignment resulting from 

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

was correctly derived. The discrepancy involves (a) transposition 

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

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

letter, or (d) errors in encipberment. 

5. Identical message indicators appeared on difrerent messages (or 

transmission sections) enciphered on the same ma.chine. 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 actua\ly used for encipherm.ent of the second message was properly tailed to the final alignment of the first message. 

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

1262, ~ara 6002a(4)) 

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

8. The message rotor alignment was transmitted in the clear as the last 

five letters ot the message indicator. (Reference AFSAG 1262, para 

6002a(5 )) 

KEY GROUP 

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

correspond to the key group actually used for encipherment. Reuse 

of a key group was not involved. (Reference .AFSAG 12621 para 5oo4-b) 

MACHINE DESIGNATOR AND MULTISWITCH SETTING 

10. The machine designator in the message indicator did not correspond to 

the multiswitch setting used for encipherment. The messages were 

(a) correctly enciphered or (b) incorrectly enciphered. (Reference 

AFSAG 12621 para 6002a(l) 

Incl 2 SECRET 
§.§..~ 

ll. Use of an urn.J.ut.horj zccl mult,i.nwi tch nett i.nG• (Hr?fercncc Afi'~3/\.G 1262, 

para G002a(2) n.ml/or J\l•':J.l\G 1~·31, par'J. GOOJo.( I)) 

ENCIPHim D~Cil'IffR C!\HD 

12. Incorrect UGc of an ORCtrJ enciphering en.rd to :prorlucc n mesSaGe 

ind:! ca tor. (Reference AF:JJ\G 1262, p::i.ra 5005c) 

13. Use i'or encipherment of o. noncffcci.ive ORCUG cncipherinB card. 

ADDTTION1\L Vl OL/\.TIONG 

14. Transmission in the clco.r of cJnm;j.f led information. 

15. Transmission of clo.ssified information i.n monoalphalJctic substi"-

tution cipher. 

16. Transmission of a message in which there wo.s faulty rotor stepping 

during encipherment. (Reference /\.F3AG 1262, po.ra 6002a(3)) 

17. Transmission of a messae;c containing an incorrect dat1:i-t.ime group.
