Statistical En-Route Filtering of Fabricated Reports in Ubiquitous Sensor Networks Based on Commutative Cipher

摘要: Summary In ubiquitous sensor networks, nodes are deployed in hostile environment, and thus vulnerable to the fabricated report injection attacks which attackers inject reports into networks through compromised deceive sink or deplete limited energy resource of forwarding nodes. this paper, we propose an enhanced version commutative cipher-based filtering scheme (CCEF), strengthens detection power CCEF by combining statistical en-route (SEF). Every is verified intermediate with a certain probability fashion both schemes. Such combined approach can provide early reports, results energy-efficiency against massive attacks. The effective proposed shown simulation at end paper.
