In this paper we propose a notion of related-key rectangle attack using 4 related keys. It is based on two consecutive related-key differentials which are independent of each other. ...
Using this attack we can break SHACAL-1 with 512-bit keys up to 70 rounds out of 80 rounds and AES with 192-bit keys up to 8 rounds out of 12 rounds, which are faster than exhaustive search. ...
Related-Key Rectangle Attack on Reduced Rounds of SHACAL-1 Firstly, we briefly describe SHACAL-1. ...

In this paper, we propose the use of a SAT-based constraint solver URSA as aid in analysis of differential trails and find that previous rectangle/boomerang attacks on XTEA and SHACAL-1 block ciphers and ...
Examples include merging two differential trail parts into one or, in the case of boomerang and rectangle attacks, connecting two short trails within the quartet boomerang setting. ...
In addition, [49] proposed a new related-key rectangle attack that works for 2 504 out of 2 512 keys. To the best of our knowledge, these are the best attacks against SHACAL-1. ...

We conclude that the probability assumptions underlying the technique make sense in real-life ciphers, and thus, related-key boomerang/rectangle attacks on block ciphers are valid in general. ...
In 2004, we introduced the relatedkey boomerang and related-key rectangle attacks, which allow to enjoy the benefits of these two techniques simultaneously. ...
Moreover, although an attack model in which the adversary has control over the key difference may seem unrealistic, a related-key differential attack on the block cipher TEA [42] was used to devise a ...
