Differential Cryptanalysis of Keccak Variants

2013
In October 2012, NIST has announced Keccak as the winner of the SHA-3 cryptographic hash function competition. Recently, at CT-RSA 2013, NIST brought up the idea to standardize Keccak variants with different parameters than those submitted to the SHA-3 competition.

FPGA implementation of new standard hash function Keccak

2014 IEEE 3rd Global Conference on Consumer Electronics (GCCE), 2014
High-speed hardware for Keccak, which was selected as a new standard hash function named SHA-3, was developed and its performance was evaluated against SHA-1 and −2 circuits through the use of various FPGA platforms. The results showed that Keccak is suitable for high-speed hardware implementations, but it is getting harder to implement on new FPGA ...

Securing MANETs Using SHA3 Keccak Algorithm

2019
As the world is going wireless, security is the primary concern. MANETs due to their dynamic nature are prone to major security risks. In few scenarios the nodes in a MANET either intentionally or unintentionally behave as selfish or malicious nodes. So identification and isolation of such nodes is necessary.

Differential Biases in Reduced-Round Keccak

2014
The Keccak hash function is the winner of the SHA-3 competition. In this paper, we examine differential propagation properties of Keccak constituent functions. We discover that low-weight differentials produce a number of biased and fixed difference bits in the state after two rounds and provide a theoretical explanation for the existence of such a ...

Cryptanalysis of 2 Round Keccak-384

2018
In this paper, we present a cryptanalysis of round reduced Keccak-384 for 2 rounds. The best known preimage attack for this variant of Keccak has the time complexity \(2^{129}\). In our analysis, we find a preimage in the time complexity of \(2^{89}\) and almost same memory is required.

FPGA-based Design Approaches of Keccak Hash Function

2012 15th Euromicro Conference on Digital System Design, 2012
Keccak hash function has been submitted to SHA-3 competition and it belongs to the final five candidate functions. In this paper FPGA implementations of Keccak function are presented. The designs were coded using HDL language and for the hardware implementation, a XILINX Virtex-5 FPGA was used.
