Abstract
Recently, He et al: [3], proposed a concrete scheme of deduplicatable dynamic PoS called DeyPoS, to
achieve dynamic PoS (Proof of Storage) and secure cross-user deduplication, simultaneously. However,
after a close look at their proposed scheme, we identity some security weaknesses. In this paper,
we show the security vulnerability of DeyPoS scheme, compromise of data privacy and unforgeability.
