FastPoS: An efficient proof of storage scheme with polynomial commitments for fog-cloud IoT systems

This academic paper describes FastPoS, a new security method for verifying that data is actually stored in fog-cloud IoT systems (networks of internet-connected devices distributed between local edge servers and central cloud storage). The method uses polynomial commitments (a cryptographic technique that lets someone prove they're storing data without revealing the data itself) to make verification faster and more efficient than existing approaches.
