Robust Node ID Assignment for Mobile P2P Networks
This addresses security issues in mobile P2P networks for users relying on portable devices, but it appears incremental as it builds on existing assignment methods.
The paper tackles the challenge of assigning unique identifiers to users in mobile peer-to-peer networks to prevent adversarial disruptions, proposing PJ-Sec, a robust node-ID assignment mechanism that was formally analyzed and found to be attack resistant.
The advancement of portable mobile wireless devices such as smart-phones, PDA, etc., brought mobile peer-to-peer (P2P) as an extension of traditional P2P networks to provide efficient, low-cost communication among them in a cellular network. It is challenging to assign a unique identifier to each user, as an adversary can target to disrupt the P2P system, by carefully selecting user IDs or obtaining many pseudo-IDs. This work proposes a robust node-ID assignment mechanism for secure peer joining in mobile P2P system called PJ-Sec. PJ-Sec facilitates to generate nodeID for a joining peer by a collaborative effort of an existing peer (within the vicinity) and pre-selected vicinity head. PJ-Sec is formally analyzed using AVISPA model checker and found to be attack resistant.
