Performance analysis of energy efficient improved LEACH protocol in IoT networks
IET Communications, Volume 19, Issue 1, January/December 2025.Abstract The Internet of Things incorporates embedded technologies, wireless sensor networks, control and automation technologies, and wearable devices to enable integrated buildings, enterprises, intelligent homes, and wearable devices. Because sensor nodes have limited power, the energy consumption of the Internet of Things network is critical.

Breaking an image encryption algorithm based on chaos
, 2011 Recently, a chaos-based image encryption algorithm called MCKBA (Modified Chaotic-Key Based Algorithm) was proposed. This paper analyzes the security of MCKBA and finds that it can be broken with a differential attack, which requires only four chosen ...

Electronics Letters, Volume 61, Issue 1, January/December 2025.ASCON has been selected by the National Institute of Standards and Technology (NIST) as the new authenticated cipher for lightweight environments. This paper analyses ASCON's hardware (HW) security through its HW implementation schemes, successful HW attacks and the proposed HW countermeasures against them, aiming to serve as a starting point for ...

Cryptanalysis of the “Kindle” Cipher [PDF]
, 2013 In this paper we study a 128-bit-key cipher called PC1 which is used as part of the DRM system of the Amazon Kindle e-book reader. This is the first academic cryptanalysis of this cipher and it shows that PC1 is a very weak stream cipher, and can be practically broken in a known-plaintext and even in a ciphertext-only scenario.

Breaking a novel colour image encryption algorithm based on chaos
, 2012 Recently, a colour image encryption algorithm based on chaos was proposed by cascading two position permutation operations and one substitution operation, which are all determined by some pseudo-random number sequences generated by iterating the Logistic

IACR Transactions on Symmetric Cryptology, 2018 At Eurocrypt 2017 the first secret-key distinguisher for 5-round AES - based on the “multiple-of-8” property - has been presented. Although it allows to distinguish a random permutation from an AES-like one, it seems rather hard to implement a key ...

Cryptanalysis of the CFVZ cryptosystem
Advances in Mathematics of Communications, 2007 The paper analyzes a new public key cryptosystem whose security is based on a matrix version of the discrete logarithm problem over an elliptic curve. It is shown that the complexity of solving the underlying problem for the proposed system is dominated by the complexity of solving a fixed number of discrete logarithm problems in the group of an ...
