Confirming conversations between Major White of this office and Major
Giraud, AFCIN, and between Major Giraud ani Major Bensey of your office,
it appears that if action is to be taken on this correspondence, it
should cone from your office. 7

Lao: “ 2. Major Floyd, AFDAT Project Officer, is not available for’ consulta-

_ 8. Tenenss). Botforaimee Oapebtiities Required: The encryption
* qlevice must be gompatible wi existing W5~117L SAMOS Subsystem F- -

oollection-trensa{esion sydtem,. It must also be compatible with the

" Gupabilities required of the encryption davice as the Project develops
an6 exact requizcaccts become known.

7. -oxonery itional Perf a i ies Desired: To provide
wetinum flexibility, the encryption shoul Loped on a
wodular construction basis and be multipurpose rather then spectalized,

_ 1f such versatility can be obtained without a serious time sacrifice,
‘The moduler construction characteristic 1s desirable as the #4NOS
Program will have an encryption requirement for different rates of

@ignal encryption as the program progresses and additional reconnaissance

” Gapabilities are developed, Although the initial encryption requirement
ts for a digital type signal, an eventual analog encryption capability
ia also desired.
