Comments on a Blockchain-Based Dynamic and Traceable Data Integrity Verification Scheme
摘要
Recently, Chen et al. designed a new data structure called linear probing Merkle hash tree (LP-MHT). They adopted LP-MHT and RSA-based homomorphic verifiable tags to propose a blockchain-based dynamic and traceable data integrity verification scheme for smart homes. They claimed that the proposed data integrity verification scheme possessed superior properties. However, after analyzing their scheme, it is found that their scheme lacks computational efficiency and verification flexibility.
