We show that oblivious transfer of bits from A to B can be obtained from a single instance of the same primitive from B to A. Our reduction is perfect and shows that oblivious tran...

Abstract. We give a provable-security treatment for the key-wrap problem, providing definitions, constructions, and proofs. We suggest that key-wrap's goal is security in the ...

To prove that a secure key-agreement protocol exists one must at least show P = NP. Moreover any proof that the sequential composition of two non-adaptively secure pseudorandom fun...
