Security Consideration in Peer-to-peer Networks with A Case Study Application

Abstract

Peer-to-Peer (P2P) overlay networks wide adoption has also created vast dangers due to the millions of users who are not conversant with the potential security risks. Lack of centralized control creates great risks to the P2P systems. This is mainly due to the inability to implement proper authentication approaches for threat management. The best possible solutions, however, include encryption, utilization of administration, implementing cryptographic protocols, avoiding personal file sharing, and unauthorized downloads. Recently a new non-DHT based structured P2P system is very suitable for designing secured communication protocols. This approach is based on Linear Diophantine Equation (LDE) [1]. The P2P architectures based on this protocol offer simplified methods to integrate symmetric and asymmetric cryptographies' solutions into the P2P architecture with no need of utilizing Transport Layer Security (TLS), and its predecessor, Secure Sockets Layer (SSL) protocols.

Design of a New Secured Hierarchical Peer-to-Peer Fog Architecture Based on Linear Diophantine Equation

“…LDEPTH is an interest based, scalable, hierarchal peer-to-peer system that provides efficient data lookup operations and fault tolerance. Most of the structured P2P systems use Distributed Hash Table (DHT) to provide efficient data insertion and lookup services, but LDEPTH employs linear Diophantine equation (LDE) to realize the hierarchal P2P architecture [8]. LDE provides a lightweight mechanism to create and maintain peer-to-peer architecture as compared to DHT.…”
