Algorithm), was developed at ETH in Zurich by James L. Massey and ! Xuejia Lai. Preliminary evidence suggests that IDEA may be more ! resistant than the DES to Biham & Shamir's highly successful ! differential cryptanalysis attack. Biham and Shamir have tried ! unsuccessfully to find any weaknesses in the IDEA cipher. Has the IDEA cipher a longer key than DES and is it thus more resistant to trying out all possible keys? Does the IDEA cipher use transpositions interleaved with substitutions or some other algorithm? Is a paper describing IDEA generally available?
