Effects of Cooperation--Based Peer-to-Peer Authentication on System Performance

摘要: Fully distributed file sharing systems, where participants share content and collaborate in a Peer--to--Peer (P2P) manner, have to deal with highly dynamic environment ensure that even when some nodes are unavailable, others can still perform the task through coalition of cooperating parties. Therefore, cooperation--based services been extensively deployed over majority P2P networks. This leads, however, significant challenges for network data management, especially facilitating security properties. In previous work, we presented protocol authentication based on attribute certificates does not rely existence public key infrastructure. Instead, peers cooperate guarantee integrity. this context, it is reasonable assume would aimed at maximizing expected benefit, but, generally, efficiency performance pays dearly this. paper, present an experimental evaluation our analytical model order validate its dependability, also discussing tolerance under failures.
