Total Break of Zorro using Linear and Differential Attacks
Zorro Differential Attack Linear Attack
2016/1/25
An AES-like lightweight block cipher, namely Zorro, was proposed in CHES 2013. While it has a 16-byte state, it uses only 4 S-Boxes per round. This weak nonlinearity was widely criticized, insofar as ...
A Generic Approach to Invariant Subspace Attacks: Cryptanalysis of Robin, iSCREAM and Zorro

2016/1/4
Invariant subspace attacks were introduced at CRYPTO 2011 to cryptanalyze
PRINTcipher. The invariant subspaces for PRINTcipher were discovered in an ad hoc
fashion, leaving a generic technique to di...

Zorro is an AES-like lightweight block cipher proposed in CHES 2013, which only uses 4 S-boxes per round. The designers showed the resistance of the cipher against various attacks and concluded the ci...
At CHES 2013 was presented a new block cipher called Zorro. Although it uses only 4 S-boxes per round, the designers showed the resistance of the cipher against various attacks, and concluded the ciph...
