WebDec 19, 2024 · The key exposure is a serious threat for the security of data integrity auditing. Once the user's private key for auditing is exposed, most of the existing data integrity auditing schemes would inevitably become unable to work. To deal with this problem, we construct a novel and efficient identity-based data integrity auditing scheme with key … WebPrevious work on Key Exposure Freeness. The problem of key exposure was partly addressed in [1], where it is shown how to build identity-based chameleon hash functions. The advantage of using the identity-based primitives is that applications could direct the use of transaction-speciﬁc chameleon hashes: The public key associated to a ...
