** Summary **

Given one way permutations (of which discrete logarithm is a candidate), we know how to construct pseudorandom functions. Today, we are going to construct pseudorandom permutations (block ciphers) from pseudorandom functions.

** Summary **

Today we give a construction of a pseudorandom permutation (block cipher) given a pseudorandom function, and we begin its analysis. Continue reading
