The table lists the average transmission delay of the
proposed VPN-based blockchain network as compared to the traditional Hyperledger fabric messages. The results
calculated from the network topology show that the average
transmission delay of a packet is 500ms in a traditional
blockchain network, whereas 700ms (200ms increased) in
the case of the proposed VPN-based blockchain network due
to the extra overhead. However, when we modeled the
routing attack, the packets were
delayed up to 20 minutes in traditional blockchain, which
leads to several problems. On the other hand, the VPN-based
traffic is secured in two layers. As a result,
the attacker can not find the source or destination of the
targeted traffic, thereby unable to predict its ASes. We
observed that there could be an additional delay of up to
1100ms if an attacker filters traffic based on an Access list
or AS filtering as listed in the Table. |
