Universally Composable Efficient Priced Oblivious Transfer from a Flexible Membership Encryption
[chapter]
2014
Lecture Notes in Computer Science
Membership encryption is a newly developed cryptographic primitive that combines membership proof and encryption into an unified setting. This paper presents a new flexible membership encryption scheme which is provably secure and significantly more efficient than the previous scheme. Further we apply our proposed membership encryption to construct a round optimal 1-outof-n priced oblivious transfer (POT) protocol which, unlike the existing 1-out-of-n POT schemes, is proven secure under the
