WSN Authentication
§Wireless
Sensor Network (WSN)
–Partially
connected network of self-powered (e.g. battery-powered) embedded processor
nodes with wireless communications interfaces and application-specific sensors
§Data
traffic: Security and privacy concerns exist in some WSN applications
–e.g.
personal medical data in a health monitoring system
§Need
to determine which WSN nodes are legitimate
–Prevent
nodes accessing sensed data without authorization.
–Configuration
of authentication should be as ‘automatic’ as possible
