“…Thus, special consideration should be put in the number of endorsers and the endorsement policy to achieve an equilibrium between a tolerable write latency and the expected number of endorsements. There are already several proposals in the literature [12] that leverage blockchains for a wide range of network applications, such as mesh networks [13], IP addresses [14], etc. The most closely related work to ours is [15], which implements Attribute-Based Access Control (ABAC) policies over the Bitcoin blockchain.…”

The specification and enforcement of network-wide policies in a single administrative domain is common in today's networks and considered as already resolved. However, this is not the case for multi-administrative domains, e.g. among different enterprises. In such situation, new problems arise that challenge classical solutions such as PKIs, which suffer from scalability and granularity concerns. In this paper, we present an extension to Group-Based Policy -a widely used network policy language-for the aforementioned scenario. To do so, we take advantage of a permissioned blockchain implementation (Hyperledger Fabric) to distribute access control policies in a secure and auditable manner, preserving at the same time the independence of each organization. Network administrators specify polices that are rendered into blockchain transactions. A LISP control plane (RFC 6830) allows routers performing the access control to query the blockchain for authorizations. We have implemented an end-to-end experimental prototype and evaluated it in terms of scalability and network latency.
