Cube-Like Attack on Round-Reduced Initialization of Ketje Sr [PDF]

IACR Transactions on Symmetric Cryptology, 2017
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.

State-Recovery Attacks on Modified Ketje Jr [PDF]

IACR Transactions on Symmetric Cryptology, 2018
In this article we study the security of the authenticated encryption algorithm Ketje against divide-and-conquer attacks. Ketje is a third-round candidate in the ongoing CAESAR competition, which shares most of its design principles with the SHA-3 hash ...

Fault Attacks on Nonce-Based Authenticated Encryption: Application to Keyak and Ketje [PDF]

Lecture Notes in Computer Science, 2019
In the context of fault attacks on nonce-based authenticated encryption, an attacker faces two restrictions. The first is the uniqueness of the nonce for each new encryption that prevents the attacker from collecting pairs of correct and faulty outputs to perform, e.g., differential fault attacks.

Practical Key-Recovery Attacks on Round-Reduced Ketje Jr, Xoodoo-AE and Xoodyak

Computer Journal, 2020
AbstractA new conditional cube attack was proposed by Li et al. at ToSC 2019 for cryptanalysis of Keccak keyed modes. In this paper, we find a new property of Li et al.’s method. The conditional cube attack is modified and applied to cryptanalysis of 5-round Ketje Jr, 6-round Xoodoo-AE and Xoodyak, where Ketje Jr is among the third round CAESAR ...

Cube-Attack-Like Cryptanalysis of Round-Reduced Keccak Using MILP [PDF]

IACR Transactions on Symmetric Cryptology, 2018
Cube-attack-like cryptanalysis on round-reduced Keccak was proposed by Dinur et al. at EUROCRYPT 2015. It recovers the key through two phases: the preprocessing phase for precomputing a look-up table and online phase for querying the output and getting ...

Pengaruh Promosi dan Harga Terhadap Kepuasan Konsumen di Kopi Ketje Bandar Lampung [PDF]

ECo-Buss
Kopi Ketje belum menetapkan harga yang cukup kompetitif di tengah meningkatnya persaingan dan kebiasaan konsumen membandingkan produk. Selain itu, promosi yang dilakukan kurang relevan karena belum memanfaatkan momen penting, sehingga belum efektif dalam usaha mendapatkan pelanggan baru dan mempertahankan yang sudah ada. Bertujuan mengevaluasi pengaruh
