Providing an efficient revocation mechanism for identity-based encryption (IBE) is very important since a user’s credential (or private key) can be expired or revealed. Revocable IBE (RIBE) is an extension of IBE that provides an efficient revocation mechanism. Previous RIBE schemes essentially use the complete subtree (CS) scheme for key revocation. In this paper, we present a new technique for RIBE that uses the efficient subset difference (SD) scheme or the layered subset difference (LSD… CONTINUE READING
