Title Cryptanalysis of LOKI91
 
Creator Knudsen, Lars Ramkilde
 
Description In this paper we examine the redesign of LOKI, LOKI91 proposed by Brown et al. First it is shown that there is no characteristic with a probability high enough to do a successful differential attack on LOKI91. Secondly we show that the size of the image of the F-function in LOKI91 is 8\22*2^32. Finally we introduce a chosen plaintext attack that reduces an exhaustive key search on LOKI91 by almost a factor 4 using 2^33+2 chosen plaintexts.
