Abstract(in English) | While key-order preserving structured overlay networks (KOPSONs) with Byzantine Fault Tolerance (BFT) are expected to have a wide range of applications, no realistic implementation has been shown. To realize KOPSON with BFT, we have proposed a structure based on keys and random numbers given by Authority and a routing scheme that constructs k redundant routes based on the structure. However, in the proposed scheme, the redundancy parameter k is a common value for all nodes, which may cause excessive redundant messages to be sent and received for a given target arrival probability. This paper proposes a method to reduce the number of messages while maintaining reachability by dynamically determining the redundancy parameter k when sending a message, assuming an environment with multiple trusted secure nodes, such as nodes deployed by service providers themselves. The results of a simulation study of the impact of varying the secure node ratio are also reported. |
