Several recent works [1-18] have addressed security issues in sensor networks.
However, most works on sensor networks consider the designs of routing
protocols and security schemes (like key management, authentication) separately.
Few works consider security issues during the design time of the routing
protocol. Since most existing routing protocols have not been designed with
security as a goal, it is unsurprising that they are vulnerable to many attacks.
However, it is non-trivial to fix the problem since it is unlikely that a sensor
network routing protocol can be made secure by incorporating security mechanisms
after the design has completed. Studies and experiences have shown
that considering security during design time is the best way to provide security
for sensor network routing.
Although one may be able to add security features to the existing routing
protocols, certain security schemes may not work e?±ciently or even correctly
with certain routing protocols. Often the routing protocols and /or security
schemes have to be modified to fit with each other, which can cause the
degradation of routing performance. Thus, the best way to provide secure
and e?±cient routing in sensor networks is to consider security during the
design time of the routing protocol.
In [5], Du and Xiao present an e?±cient key management scheme and a
secure routing protocol - Secure Cell Relay (SCR) for sensor networks.
