Cryptanalysis of KLEIN (Full version)
KLEIN lightweight block cipher truncated differential cryptanalysis
2016/1/26
Due to the recent emergence of resource-constrained devices, cryptographers are
facing the problem of designing dedicated lightweight ciphers. KLEIN is one of the resulting
primitives, proposed at R...
An Improved Truncated Differential Cryptanalysis of KLEIN
KLEIN Truncated Differential Attack
2016/1/9
KLEIN is a family of lightweight block ciphers which proposed
at RFIDSec 2011 by Gong et al. It has a 64-bit state and 64, 80 or
96-bit key size which introduce its version. It uses 16 same 4-bit Sb...
Power Analysis Attacks against FPGA Implementations of KLEIN
power analysis attack KLEIN FPGA
2013/4/18
KLEIN is a family of block ciphers proposed by Zheng Gong et al. at RFIDSec 2011, and its lightweight features are suitable for resource-constrained devices. However, the original design of KLEIN does...
Biclique Cryptanalysis of the Full-Round KLEIN Block Cipher
lightweight cryptography biclique attack KLEIN family
2013/4/18
In this paper we present a biclique attack on the newly proposed block cipher KLEIN-64. We first introduce some weaknesses of the diffusion layer and key schedule of this algorithm. Then we exploit th...
