Web1 Jul 2013 · Only the users outside S can decrypt the broadcast ciphertext. Attribute-Based Encryption ABE is a useful cryptographic primitive which enables flexible access policy over encrypted data. In this paper, we propose an adaptively secure broadcast revocation scheme in composite-order bilinear group.
WebFurthermore, our laconic encryption can be preprocessed such that the online encryption step is entirely combinatorial and therefore much more efficient. Using similar techniques, we also obtain identity-based encryption with an unbounded identity space and tight security proof (in the standard model). eva magyarováWeb1 day ago · Reverse the order of lines in a text file while preserving the contents of each line.
