- It's important for a spy to not be obvious. A custom crypto program is more
- obvious than one in "widespread" use. Mailing to boris@kremvax.Xussr is more
- obvious than posting GIFs (as someone else suggested). You didn't comment on
- this aspect. For a fictitious example, The Cardinal of the Kremlin disguised
- his messages as diary entries. That way he could plausibly deny that they
- were anything more than diary entries.
-
- We (readers of sci.crypt) have a belief that PGP is secure because we believe
- that very large numbers are "impossible" to factor, and that IDEA is difficult
- to break given frequent key changes. Perhaps the NSA and its counterparts have
- reached the same conclusions. In that case, it would be quite reasonable to
- have lower level spies (perhaps only industrial ones as you suggest) use PGP.
-
- I'm not really a student of bureaucracy but I'll suggest that Not Invented
- Here would be a bigger obstacle keeping an agency from adopting PGP than any
- weaknesses in it. There is a general consensus that real spooks disparage the
- use of factoring based cryptosystems, but perhaps *that* is disinformation.
