Abstract

This paper presents SCUBA (Secure Code Update By Attestation), for detecting and recovering compromised nodes in sensor networks. The SCUBA protocol enables the design of a sensor network that can detect compromised nodes without false negatives, and either repair them through code updates, or revoke the compromised nodes. The SCUBA protocol represents a promising approach for designing secure sensor networks by proposing a first approach for automatic recovery of compromised sensor nodes. The SCUBA protocol is based on ICE (Indisputable Code Execution), a primitive we introduce to dynamically establish a trusted code base on a remote, untrusted sensor node.
