Computational resource constrained or lossy networks (LNs) are increasingly being used as a low-cost alternative to supporting community-based service oriented architectures (SoAs) in economically challenged and/or technologically poor areas. LNs are typically characterized by embedded devices with limited power, memory, and processing resources. Application areas range from building automation to wireless healthcare and energy metering on smart/microgrids.
Services provided over LNs are to large degree supported by user participation and so service providers need to provide users with firm guarantees of network reliability and dependability. Failure to do so, results in a loss of trust on the part of the users and a refusal to participate in or support the network. Lack of user cooperation can ultimately result in a breakdown of the network, which is undesirable.
This talk considers security and privacy from the perspective of LN adversarial manipulations that provoke disruptions to affect LN stability negatively. Examples of why and how such adversarial situations are provoked and some of preliminary solutions are discussed.
