State-Recovery Attacks on Modified Ketje Jr
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 ...

Cube-like Attack on Round-Reduced Initialization of Ketje Sr
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.

Guards in Action: First-Order SCA Secure Implementations of Ketje Without Additional Randomness [PDF]
2018 21st Euromicro Conference on Digital System Design (DSD), 2018 Abstract Recently the CAESAR competition has announced several finalists among the submitted authenticated encryption algorithms, after an open selection process during the last five years. Applications using these algorithms are rapidly increasing today.

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 ...

Fault Attacks on Nonce-Based Authenticated Encryption: Application to Keyak and Ketje
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.

Pengaruh Promosi dan Harga Terhadap Kepuasan Konsumen di Kopi Ketje Bandar Lampung
ECo-BussKopi 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
