In this paper we present a new 128-bit block cipher called SQUARE. The original design of SQUARE concentrates on the resistance against differential and linear cryptanalysis. However, after the initial design a dedicated attack was mounted that forced us to augment the number of rounds. The goal...

or both. By keeping the parameters secret, rather than the algorithm family, both contradictory requirements can be achieved. Provided that the family of parameters is large enough (possibly infinite) and each of its
The iteration function in Figure 4 takes in the 1600 bits of data and then puts it through 24 rounds of permutation using a specific algorithm and then passes it to the next stage as a 1600-bit block. This continues until the absorbing phase has completed. ...

The algorithm can be modified by performing multiple levels of jump search on the sublists, before finally performing the linear search. For an k-level jump search the optimum block size ml for the lth level (counting from 1) is n(k-l)/k. The modified algorithm will perform k backward ...
