Let g be an element of prime order p in an abelian group and Zp. We show that if g, g , and gd are given for a positive divisor d of p - 1, we can compute the secret in O(log p

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...

We show that, in the ideal-cipher model, triple encryption (the cascade of three independently-keyed blockciphers) is more secure than single or double encryption, thereby resolvin...
