ABSTRACT: This talk will present SAMNAR, a survivable architecture inspired on the human body immune system. The architecture aims to maintain essential services of self-organizing wireless networks, as link-layer connectivity, routing and end-to-end communication, even under attacks or intrusions. It employs a new approach for security management, consisting in the adaptive coordination of preventive, reactive and tolerant defense lines. Preventive security mechanisms, such as cryptography, are the first protection of the network, blocking some attacks. Reactive security mechanisms, such as intrusion detection systems, are the second protection, detecting and reacting against intrusions. Tolerant security mechanisms are the third protection, mitigating intrusion or attack effects until preventive or reactive defense lines can adapt. We apply SAMNAR in two case studies. The first one proposes a survival path selection scheme for routing service. The scheme correlates criteria provided by three defense lines using Fuzzy Logic in order to choose the most survivable path. The second one proposes a survivable public key management system (PKI), aiming to manage and distribute cryptographic keying material in a survivable way. Our PKI is fully decentralized using different evidences to prove the liability of users for their public keys. Finally, we provide research directions related to survivable link-layer connectivity considering advanced wireless communication technology, as cognitive radio.
