| Summary: | 碩士 === 國立清華大學 === 資訊工程學系 === 100 === This thesis proposes EcoSec, a thin security layer for supporting
secure access and macroprogramming of wireless sensor networks
consisting of ultra-compact, resource-constrained nodes with a
gateway. The user names the requested resource in the WSN in the
form of a uniform resource identifier (URI). The user must be
authenticated first and access rights checked by a trusted
authentication mechanism, which sends a signed request back to the
user along with the code fragment for access. The gateway checks and
rewrites code to enforce access rights and sends the code to the
node; the node checks the code signature before execution. This
approach is lightweight enough to run on some of the most
resource-constrained wireless sensor platforms such as Eco.
Moreover, it is sufficiently lightweight that it can be easily
integrated with a lightweight macroprogramming and interactive
programming environment called EcoCast.
Experimental results show that EcoSec in conjunction with EcoCast
run with minimal overhead while taking only a few KB of code and
data memory.
