Elastic Trust Management in Decentralized Computing Environments

Today, the Internet trust is a critical framework that forms fundamental premise for network security. Several identity federations are deployed to embody classic theory of framework. However, in an emerging blockchain-based decentralized system, we need model dynamically grown/shrunken trust. This paper models elasticity by formalizing PDP(policy decision point)s enrolling entities and introducing Trust PDP. In proposed formalization, assertions exchanged among participating nodes express knowledge PDP nodes. The may grow exchanging assertions. Furthermore, propose on relationship judgment operated affects applied establishment blockchain authorization management system based blockchain. environment expressed terms
