Cube-like Attack on Round-Reduced Initialization of Ketje Sr
This paper studies the Keccak-based authenticated encryption (AE) scheme Ketje Sr against cube-like attacks. Ketje is one of the remaining 16 candidates of third round CAESAR competition, whose primary recommendation is Ketje Sr. Although the cube-like method has been successfully applied to Ketje’s sister ciphers, including Keccak-MAC and Keyak – another Keccak-based AE scheme, similar attacks...
متن کاملConditional Cube Attack on Round-Reduced ASCON
This paper evaluates the secure level of authenticated encryption Ascon against cube-like method. Ascon submitted by Dobraunig et al. is one of 16 survivors of the 3rd round CAESAR competition. The cube-like method is first used by Dinur et al. to analyze Keccak keyed modes. At CT-RSA 2015, Dobraunig et al. applied this method to 5/6-round reduced Ascon, whose structure is similar to Keccak key...
متن کاملCube Attacks and Cube-Attack-Like Cryptanalysis on the Round-Reduced Keccak Sponge Function
In this paper, we comprehensively study the resistance of keyed variants of SHA-3 (Keccak) against algebraic attacks. This analysis covers a wide range of key recovery, MAC forgery and other types of attacks, breaking up to 9 rounds (out of the full 24) of the Keccak internal permutation much faster than exhaustive search. Moreover, some of our attacks on the 6-round Keccak are completely pract...
متن کاملConditional Cube Attack on Reduced-Round Keccak Sponge Function
Since Keccak was selected as SHA-3 hash function by NIST, it has attracted considerable attention from cryptographic researchers. Keccak sponge function [1] has also been used to design message authentication codes (MAC) and authenticated encryption (AE) scheme Keyak. Till now, the most efficient key recovery attacks on Keccak-MAC and Keyak are cube attacks and cube-attack-like cryptanalysis pr...
متن کاملConditional Cube Attack on Round-Reduced River Keyak
This paper evaluates the security level of the River Keyak against the cube-like attack. River Keyak is the only lightweight scheme of the Keccak-permutation-based Authenticated Encryption Cipher Keyak, which is one of the 16 survivors of the 3rd round CAESAR competition. Dinur et al. gave the sevenround cube-like attack on Lake Keyak (1600-bit) using the divide-and-conquer method at EUROCRYPT ...
