Improved Rectangle Attacks on SKINNY and CRAFT
IACR Transactions on Symmetric Cryptology, 2021 The boomerang and rectangle attacks are adaptions of differential cryptanalysis that regard the target cipher E as a composition of two sub-ciphers, i.e., E = E1 ∘ E0, to construct a distinguisher for E with probability p2q2 by concatenating two short ...

Rectangle Attacks on 49-Round SHACAL-1 [PDF]
, 2003 SHACAL-1 is a 160-bit block cipher with variable key length of up to 512-bit key based on the hash function SHA-1. It was submitted to the NESSIE project and was accepted as a finalist for the 2nd phase of the evaluation. In this paper we present rectangle attacks on 49 rounds out of the 80 rounds of SHACAL-1.

Related-Key Rectangle Attack of the Full HAS-160 Encryption Mode [PDF]
Lecture Notes in Computer Science, 2009 In this paper we investigate the security of the encryption mode of the HAS-160 hash function. HAS-160 is a Korean hash standard which is widely used in Korean industry. The structure of HAS-160 is similar to SHA-1 besides some modifications. In this paper, we present the first cryptographic attack that breaks the encryption mode of the full 80-round ...

New related-key rectangle attack on 42-round SHACAL-2
Tongxin xuebao, 2009 A new 34-round related-key rectangle distinguisher was constructed by exploiting the properties of the round transform of SHACAL-2. Moreover, two new relate-key rectangle attacks on 40-round and 42-round reduced SHACAL-2 were presented by using both the ...

Related-key rectangle attack on the full ARIRANG encryption mode
Tongxin xuebao, 2011 The security of the block cipher used in the compression function of ARIRANG,which was one of the SHA-3 candidates,was revaluated.Based on a linear transformation of the master key and the all-one differential of the round function,a full 40-round ...

Related-Key Rectangle Attacks on Reduced AES-192 and AES-256 [PDF]
, 2007 This paper examines the security of AES-192 and AES-256 against a related-key rectangle attack. We find the following new attacks: 8-round reduced AES-192 with 2 related keys, 10-round reduced AES-192 with 64 or 256 related keys and 9-round reduced AES-256 with 4 related keys.
