Efficient reduction of 1 out of n oblivious transfers in random oracle model
oblivious transfer secure reduction
2009/2/25
We first present a protocol which reduces 1-out-of-n oblivious transfer OTml
to 1-out-of-n oblivious transfer OTk m for n > 2 in random oracle model, and show that
the protocol is secure against mal...

Extending Oblivious Transfers Robustness Efficiently
2008/8/25
At Crypto 2003 Ishai et al. gave a protocol which given a small number of (possibly
extremely inefficient) oblivious transfers implements an essentially unbounded number of
oblivious transfers for a...
