Data security in multiparty edge computing environments

The paper considers data security issues in edge computing scenarios that involve data streams coming out from individual devices to edge controllers (ECs). We assume multiple edge controllers each possibly belonging to a different party and controlling some devices. In this environment, there are issues in regards to the scalability of key management and computation limitations at the edge of the network. To address these issues, we suggest the formation of groups in the device layer, where a group leader is assigned to communicate with group devices and the EC. We propose a lightweight permutation mechanism for preserving the confidentiality of sensory data. Keywords—Edge Computing; Data Security; IoT; Multitenancy; Scalability; Access Control
