Abstract
A device, system, and method for decentralized management of a distributed proxy re-encryption key ledger by multiple devices in a distributed peer-to-peer network. A network device may receive shared data defining access to a proxy re-encryption key. The network device may locally generate a hash code based on the shared data. The network device may receive a plurality of hash codes generated based on versions of the shared data at a respective plurality of the other devices in the network. If the locally generated hash code matches the received plurality of hash codes, the network device may validate that the shared data is the same across the network devices and may add the received proxy re-encryption key access data and locally generated hash code to a local copy of the distributed proxy re-encryption key ledger.
