Summary: The authors present a method for efficient conversion of differential (chosen plaintext) attacks into the more practical known plaintext and ciphertext-only attacks. Their observation may save up to a factor of $2^{20}$ in data over the known methods, assuming that plaintext is ASCII encoded English (or some other types of highly redundant data). They demonstrate the effectiveness of their method by practical attacks on the block-cipher Madryga and on round-reduced versions of RC5 and DES.
