New Results on Boomerang and Rectangle Attacks
The boomerang attack is a new and very powerful cryptanalytic technique. However, due to the adaptive chosen plaintext and ciphertext nature of the attack, boomerang key recovery attacks that retrieve key material on both sides of the boomerang distinguisher are hard to mount. We also present a method for using a boomerang distinguisher, which enables retrieving subkey bits on both sides of the...
متن کاملRelated-Key Boomerang and Rectangle Attacks
This paper introduces the related-key boomerang and the related-key rectangle attacks. These new attacks can expand the cryptanalytic toolbox, and can be applied to many block ciphers. The main advantage of these new attacks, is the ability to exploit the related-key model twice. Hence, even ciphers which were considered resistant to either boomerang or related-key differential attacks may be b...
متن کاملBoomerang Attacks on BLAKE-32
We present high probability differential trails on 2 and 3 rounds of BLAKE-32. Using the trails we are able to launch boomerang attacks on up to 8 round-reduced keyed permutation of BLAKE-32. Also, we show that boomerangs can be used as distinguishers for hash/compression functions and present such distinguishers for the compression function of BLAKE-32 reduced to 7 rounds. Since our distinguis...
متن کاملExtending commutative diagram cryptanalysis to slide, boomerang, rectangle and square attacks
Encryption algorithms that use the same secret key for encryption and decryption (also known as block ciphers) allow confidential information to be protected and accessible only by legitimate parties who have knowledge of that secret key. Before the public can be comfortable with using a block cipher, it needs to gain public trust on its level of security. Over the years, the approach has been ...
متن کاملThe Boomerang Attacks on BLAKE and BLAKE2
In this paper, we study the security margins of hash functions BLAKE and BLAKE2 against the boomerang attack. We launch boomerang attacks on all four members of BLAKE and BLAKE2, and compare their complexities. We propose 8.5-round boomerang attacks on both BLAKE-512 and BLAKE2b with complexities 2 and 2 respectively. We also propose 8-round attacks on BLAKE256 with complexity 2 and 7.5-round a...
