SCUBA: Secure Code Update By Attestation in sensor networks

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.
