The Trusted and Decentralized Network Resource Management

Network resource management relies on trusted infrastructures. However, current trusted infrastructures have centralized or hierarchical structures where root nodes often have privileges over subtrees. Hacked or malicious roots may affect subtrees by modifying IP ownership, routing and so on. Therefore, a trusted and decentralized network resource management becomes crucial. The emergence of blockchain such as Ethereum becomes a leading candidate for achieving trusted and decentralized network resource management. In this paper, based on Ethereum, we design a trusted authentication scheme that includes voting policy, endorsement, credibility model and rebinding mechanism to ensure the credibility of entities. Our scheme can allocate, delegate and transfer network resources in a trusted and decentralized style. The experimental results verify the feasibility and security of our scheme. When an entity is hacked or malicious, its endorsement authentication is revoked and the entity does not have the right to manage the network resources. In addition, the overhead increased by the trusted authentication scheme is within a reasonable range.
