A Generic Construction for Revocable Identity-Based Encryption with Subset Difference Methods
Revocable identity-based encryption Subset difference method Generic construction
2019/7/15
To deal with dynamically changing user's credentials in identity-based encryption (IBE), providing an efficient key revocation method is a very important issue. Recently, Ma and Lin proposed a generic...
