- Abstract
- Openstack is widely used as a representative open-source infrastructure of the service (IaaS) platform. TheOpenstack Identity Service is a centralized approach component based on the token including the Memcachedfor cache, which is the in-memory key-value store. Token validation requests are concentrated on thecentralized server as the number of differently encrypted tokens increases. This paper proposes the practicalByzantine fault tolerance (PBFT) blockchain-based Openstack Identity Service, which can improve theperformance efficiency and reduce security vulnerabilities through a PBFT blockchain framework-baseddecentralized approach. The experiment conducted by using the Apache JMeter demonstrated that latency wasimproved by more than 33.99% and 72.57% in the PBFT blockchain-based Openstack Identity Service,compared to the Openstack Identity Service, for 500 and 1,000 differently encrypted tokens, respectively.
