Title:
A Note on ``Secure and Distributed IoT Data Storage in Clouds Based on Secret Sharing and Collaborative Blockchain’’
Authors: Zhengjun Cao, Lihua Liu
Abstract:We show that the data storage scheme [IEEE/ACM Trans. Netw., 2023, 31(4), 1550-1565] is flawed due to the false secret sharing protocol, which requires that some random 4\times 4 matrixes over the finite field F_p (a prime p) are invertible. But we find its mathematical proof for invertibility is incorrect. To fix this flaw, one needs to check the invertibility of all 35 matrixes so as to generate the proper 7 secret shares.
