This paper presents the ECCE Protocol, a new dis- tributed, probabilistic, cooperative protocol to establish a secure pair-wise communication channel between any pair of sensors in a Wireless Sensor Network (WSN). The main contribution of the ECCE Protocol is to allow the set up of a secure channel between two sensors (princi- pals) that do not share any pre-deployed key. This fea- ture is obtained involving a set of sensors (cooperators) in the channel establishment protocol. Further, the secu- rity provided by the protocol is adaptive with the level of threat in the WSN, that is, the higher the security threat, the more cooperators can be involved to enhance the re- siliency of the channel. We provide extensive simulations of the proposed scheme, which show that ECCE increases both the prob- ability of a secure channel set up and the probability of channel resilience with respect to other protocols.

Abstract

This paper presents the ECCE Protocol, a new dis- tributed, probabilistic, cooperative protocol to establish a secure pair-wise communication channel between any pair of sensors in a Wireless Sensor Network (WSN). The main contribution of the ECCE Protocol is to allow the set up of a secure channel between two sensors (princi- pals) that do not share any pre-deployed key. This fea- ture is obtained involving a set of sensors (cooperators) in the channel establishment protocol. Further, the secu- rity provided by the protocol is adaptive with the level of threat in the WSN, that is, the higher the security threat, the more cooperators can be involved to enhance the re- siliency of the channel. We provide extensive simulations of the proposed scheme, which show that ECCE increases both the prob- ability of a secure channel set up and the probability of channel resilience with respect to other protocols.
