A note on ``faster and efficient cloud-server-aided data de-duplication scheme with an authenticated key agreement for Industrial Internet-of-Things''

Abstract

We show that the data de-duplication scheme [Internet of Things, 2021(14): 100376] is flawed. (1) There are some inconsistent notations and false equations, which should be corrected. (2) The scheme fails to keep user anonymity, not as claimed. (3) The scheme could fail to keep data confidentiality.
