Homomorphic Token and Distributed Erasure-Code for cloud
Cloud users store their data in the cloud environment which is privileged by the service provider. Cloud users can access their cloud storage. Here, the authors propose a flexible distributed storage integrity auditing mechanism, utilizing the homomorphic token and distributed erasure-coded data. The proposed design allows users to audit the cloud storage with very lightweight communication and computation cost. The proposed scheme is highly efficient and resilient against Byzantine failure, malicious data modification attack, and even server colluding attacks.
