Secure Algorithms for SAKA Protocol in the GSM Network [PDF]
, 2017 This paper deals with the security vulnerabilities of the cryptographic algorithms A3, A8, and A5 existing in the GSM network. We review these algorithms and propose new secure algorithms named NewA3, NewA8, and NewA5 algorithms with respect to the A3 ...

On the Security of Y-00 under Fast Correlation and Other Attacks on the Key [PDF]
, 2006 The potential weakness of the Y-00 direct encryption protocol when the encryption box ENC in Y-00 is not chosen properly is demonstrated in a fast correlation attack by S. Donnet et al in Phys. Lett. A 35, 6 (2006) 406-410.

Provable security against generic attacks on stream ciphers
Journal of Mathematical Cryptology, 2023 Recent lightweight hardware-based stream cipher designs keep an external non-volatile internal state that is not part of the cipher’s hardware module. The purpose of these so-called small-state ciphers is to keep the size of the hardware and the power ...

MV3: A new word based stream cipher using rapid mixing and revolving buffers [PDF]
, 2006 MV3 is a new word based stream cipher for encrypting long streams of data. A direct adaptation of a byte based cipher such as RC4 into a 32- or 64-bit word version will obviously need vast amounts of memory. This scaling issue necessitates a look for new

BLOSTREAM: A HIGH SPEED STREAM CIPHER [PDF]
Journal of Engineering Science and Technology, 2017 Although stream ciphers are widely utilized to encrypt sensitive data at fast speeds, security concerns have led to a shift from stream to block ciphers, judging that the current technology in stream cipher is inferior to the technology of block ciphers.

Hybrid Cipher System using Neural Network
مجلة بغداد للعلوم, 2008 The objective of this work is to design and implement a cryptography system that enables the sender to send message through any channel (even if this channel is insecure) and the receiver to decrypt the received message without allowing any intruder to ...

Block and Stream Ciphers and the Creatures in Between [PDF]
, 2007 In this paper we define a notion of leak extraction from a block cipher. We demonstrate this new concept on an example of AES. A result is LEX: a simple AES-based stream cipher which is at least 2.5 times faster than AES both in software and in ...

Side Channel Attack On Stream Ciphers: A Three-Step Approach To State/Key Recovery
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Side Channel Attack (SCA) exploits the physical information leakage (such as electromagnetic emanation) from a device that performs some cryptographic operation and poses a serious threat in the present IoT era. In the last couple of decades, there have
