DoD  Directive  C-5200-5,    "Communications   Security 
(COMSEC)    (U),"     October  27,    1958 
DoD  Instruction  3135-1,    "Criteria  for  Ensuring  the 
Competency  of  Personnel   to  Install,   Maintain  and 
Repair  Cryptographic  Equipment,"    June  k,    1963 
(hereby  cancelled) 
PURPOSE  AND  OBJECTIVE 
DDR.&E 
A.  This  Instruction  establishes  policy  and  criteria  which  will 
ensure  that  only  fully  qualified  personnel  install,  maintain 
and  repair  cryptographic  equipment,  and  assigns  responsibilities 
for  carrying  out  its  provisions. 
B.  Its  objective  is  to  retain  the  security  inherent  in  crypto- 
graphic equipment  through  adequate  equipment  installation, 
maintenance,  and  repair. 
II.  APPLICABILITY 
The  provisions  of  this  Instruction  apply  to  all  Department  of 
Defense  Components  utilizing  cryptographic  equipment,  as  defined 
in  reference  (a) . 
III.  CANCELLATION 
Reference  (b)  is  hereby  superseded  and  cancelled. 
IV.  POLICY 
A. 
The  complexity  and  nature  of  modern  cryptographic  equipment 
places  the  maintenance  technician  in  a  critical  position  of 
responsibility  for  maintenance  and  operational  security  of 
such  equipment.   Since  his  proficiency  is  largely  dependent 
on  the  quality  and  amount  of  maintenance  training  received 
and  the  extent  of  experience  acquired  in  applying  this  know- 
ledge, all  DoD  Components  involved  will  ensure  that: 
1. 
Only  personnel  formally  trained  in  at  least  the  knowledge 
and  skills  covered  by  appropriately  written  courses  of 
instruction  prepared  or  approved  by  the  National  Security 
Agency  (NSA)  (see  also  VI.  B)  are  permitted  to  install, 
maintain  and  repair  cryptographic  equipment.
2.   Supervisory  personnel  are  provided  with  criteria  for  deter- 
mining the  maintenance  proficiency  of  technicians  on  a 
particular  equipment  before  such  maintenance  technicians  are 
assigned  responsibility  for  its  installation,  maintenance,  and 
repair. 
3-  Cryptographic  equipment  installation,  maintenance  and  repair 
is  accomplished  in  accordance  with  applicable  cryptosecurity 
rules,  regulations,  procedures,  and  instructions  prescribed 
or  approved  by  NSA.  This  reauirement  is  not  to  be  construed 
as  relieving  individual  DoD  Components  of  responsibility  for 
prescribing  supplementary  security  procedures  leauired  for 
unique  application  within  their  respective  organizations. 
Full  consideration  must  be  given  to  achieving  maximum  economies 
"hrcugh : 
1.  Introduction  and  use  of  maintenance  methods  which  exploit 
equipment  design  and  construction  advances. 
2.  Consolidation  on  an  inter- Service  basis,  where  practicable 
of  cryptographic  equipment  training  courses. 
■3. 
The  use  of  established  Government,  rather  than  contractor, 
training  facilities. 
V.   CRITERIA 
In  accomplishing  the  objective  of  this  Instruction,  all  DoD  Components 
concerned  will,  as  a  minimum,  adhere  to  the  following  criteria: 
A.  The  scope  of  and  graduation  requirements  for  their  courses  of 
instruction  will  be  maintained  at  a  level  sufficient  to  ensure 
that  personnel  who  will  install,  maintain,  and  repair  crypto- 
graphic equipment  are  properly  qualified  in  all  aspects  of  their 
assigned  responsibilities. 
B.  DD  Form  1*4-35,  "Cryptographic  Maintenance  Training  and  Experience 
Record,"  (Enclosure  l)  will  be  completed  for  each  technician  who 
completes  a  cryptographic  maintenance  course.   DD  Form  1*4-35  may  be 
used  as  a  graduation  certificate.  This  form  shall  constitute  a 
chronological  record  of  all  cryptographic  training  and  maintenance 
experience  received  by  the  individual,  and  shall  become  a  permanent 
part  of  each  individual's  permanent  command  and  field  personnel 
record.  Each  form  shall  be  reviewed  and  updated  every  twelve  (12) 
months  and  prior  to  a  permanent  change  of  station. 
C.   Supervisory  personnel  will  thoroughly  review  the  DD  Form  1*4-35  of 
each  technician  to  ensure  that  he  meets  the  training  and  experience 
requirements  on  a  particular  equipment  before  assigning  him  respon- 
sibility for  its  installation,  maintenance,  and  repair.
3135-1  ^ 
Sept  13*  oS 
D.  Previously  treined  end  qualified  personnel  who  no  longer  meet  the 
requirements  for  installing,  maintaining  and  repairing  a  particular 
equipment  because  (l)  they  have  not  had  training  or  experience  in 
maintaining  that  cryptographic  equipment  within  the  preceding  36 
months,  or  (2)  major  changes  have  been  made  to  the  equipment,  will 
be  retrained  or  requalified  by  approved  examination.   (Personnel 
trained  to  perform  only  limited  maintenance  are  excluded  from  this 
requirement. ) 
E.  When  contractor  or  field-type  training  is  used,  such  training  courses 
will; 
1.  Ee  approved  by  the  appropriate  training  authority  of  the  Military 
Department  or  other  DoD  Component  using  such  services. 
2.  Use  only  training  material  furnished  or  approved  by  NSA  or  the 
appropriate  training  authority  of  the  Military  Departments  or 
other  DcD  Components,  as  applicable. 
3.  Be  conducted  cy   instructors  who  meet  the  qualification  require- 
ments of  their  counterparts  at  established  Military  Department 
or  other  DoD  Component  training  facilities. 
VI.   RESPONSIBILITIES 
A.  The  Director,  National  Securitv  Agency,  shsll  establish  guidelines 
and  provide  technical  guidance  and  support  for  cryptographic  equip- 
ment technical  training  conducted  by  DoD  Components,  furnishing  such 
agencies  with: 
1.  Initial  training  necessary  for  the  successful  introduction  to 
the  maintenance  and  repair  of  each  newly  developed  NSA  crypto- 
graphic equipment. 
2.  Approved  courses  of  instruction  which  constitute  the  minimum 
standards  for  maintenance  training  on  crypto-equipment. 
3«   Guidelines  and  minimum  standards  for  the  preparation  and  conduct 
cf  courses  of  instruction  on  crypto-equipment  delegated  to  the 
Military  Departments  for  development. 
k.      Such  additional  technical  guidance  and  support  as  is  required  to 
accomplish  the  objectives  of  this  Instruction. 
B.  The  Military  Departments  shall: 
1.  Provide  maintenance  training  as  required  to  support  their 
operational  use  of  crypto-equipment  in  consonance  with  the 
policy  and  criteria  stated  in  sections  IV  and  V.
2.   Prepare  and  teach  trie  information  required,  ir.  addition  to 
that  provided  in  the  USA   approved  course,  to  support  use  of 
the  crypto-equipments  in  their  system  applications. 
3-  Determine  that  their  crypto-equipmer.t  training  requirements 
cannot  be  met  adequately  by  courses  elsewhere  in  DoD  before 
establishing  a  new  course. 
4.   Prepare,  and  send  to  N3A  for  epproval,  written  courses  of 
instruction  on  crypto -equipment  delegated  for  development. 
5-   Provide  the  necessary  initial  maintenance  training  support 
for  crypto-equipment  delegated  to  them  for  development.
