講座內(nèi)容：We construct an efficient private-key functional encryption (FE) for inner-products (linear FE) with full-hiding security, where confidentiality is assured not only for encrypted data but also for functions associated with secret keys. Our scheme is constructed on the dual pairing vector spaces (DPVS) and has an advantage over the previous schemes in the efficiency, assumptions and flexibility.
