Wireless sensor networks might be used for security purposes - they enable  fast deploying 
of a network almost anywhere - regardless of environment conditions. In particular, they
 can be used in a battlefield, the luck of wires as well as high degree of freedom
for devices location make them quite robust against attacks.

In this paper we present a method for encrypting and routing messages in such a network. 
The protocol depends heavily  on the assumption that an adversary may find easily some 
of the sensors and seize control over them, but it is quite hard for him to find all 
of them quickly. We propose it as adversary model for networks of this kind.
