Abstract
Our contribution de nes a conjunction operator for
private stream searching, integrates this operator into
a high level language, and describes the system facets
that achieve a realization of private packet ltering.
Private stream searching uses an encrypted lter to
conceal search terms, processes a search without decrypting
the lter, and saves encrypted results to an
output bu er. Our conjunction operator is processed
as a bitwise summation of hashed keyword values
and as a reference into the lter. The operator thus
broadens the search capability, and does not increase
the complexity of the private search system. When
integrated into the language, cyber defenders can
lter packets using sensitive attack indicators, and
gain situational awareness without revealing those
sensitive indicators.
