In recent years, ,more and more wireless sensor networks have been
put into application and they go deep into the military detection ,the
resource protection and other data-sensitive areas. The security of
wireless sensor work is the important guarantee of the normal eliminates
the interference of the enemy, normally interacts with the users and
provides the data for the decision. But it is a great challenge ,because
the nodes in the wireless sensor network are limited to their
energy,memories,computing capability and own security.
This paper is proposed to review five security technologies: key
management, secure routing,intrusion detection ， data fusion and
n ode security positioning technology .
1. Conduct research for key management in wireless sensor network
environment .Analyze and summary the E-G scheme ,the multi-path key
enhanced scheme ,the q-composite scheme, the Blom and its derivative
schemes ,the LIU-NING+B pre-distribution scheme ,the Key management scheme
based on the location and other auxiliary information （ D-P scheme ） ,the
pre-distribution scheme based on the combination of design theory ,the key
management scheme based on node attributes set ,the SPIN protocol ,the key
management scheme based on asymmetric cryptography and the key update
