Here, we prove . bounds on the security of key-alternating ciphers and extend them to XOR cascades, the most efficient construction for key-length extension. Our bounds essentially match, for any possible

We devise information-theoretically secure protocols that allow additional pairs of parties to establish secure OT correlations using the h
