A Lightweight Implementation of Keccak Hash Function for Radio-Frequency Identification Applications

Lecture Notes in Computer Science, 2010
In this paper, we present a lightweight implementation of the permutation Keccak-f[200] and Keccak-f[400] of the SHA-3 candidate hash function Keccak. Our design is well suited for radio-frequency identification (RFID) applications that have limited resources and demand lightweight cryptographic hardware.

Denying Collision in the Second Round of Keccak Hash Function by Camouflaging Free Bits [PDF]

2016 4th International Conference on Information and Communication Technology (ICoICT), 2016
Keccak Hash Function is the winner of SHA3 competition. Hash function collision has become one of the fundamental problem in Keccak Hash Function. One of the attack which is based on collision has been proposed by Plasencia, et.al. They proposed the practical analysis of reduced round Keccak Hash Function, such that the collision will be found in the ...

GPU Implementation of the Keccak Hash Function Family

Communications in Computer and Information Science, 2011
Hash functions are one of the most important cryptographic primitives. Some of the currently employed hash functions like SHA-1 or MD5 are considered broken today. Therefore, in 2007 the US National Institute of Standards and Technology announced a competition for a new family of hash functions.

Implementation of High Speed Hash Function Keccak on GPU

International Journal of Networking and Computing, 2019
Nowadays, a hash function is used for password management. The hash function is desired to possess the following three characteristics: Pre-Image Resistance, Second Pre-Image Resistance, and Collision Resistance. They are set on the assumption that it is computationally difficult to find the original message from a given hash value.

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 ...

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.

Non-Full Sbox Linearization: Applications to Collision Attacks on Round-Reduced Keccak [PDF]

Lecture Notes in Computer Science, 2017
The Keccak hash function is the winner of the SHA-3 competition and became the SHA-3 standard of NIST in 2015. In this paper, we focus on practical collision attacks against round-reduced Keccak hash function, and two main results are achieved: the first

A SAT-Based Preimage Analysis of Reduced Keccak Hash Functions

Information Processing Letters, 2013
Abstract In this paper, we present a preimage attack on reduced versions of Keccak hash functions. We use our recently developed toolkit CryptLogVer for generating the conjunctive normal form, CNF, which is passed to the SAT solver PrecoSAT. We found preimages for some reduced versions of the function and showed that full Keccak function has a ...
