Strumok stream cipher: Specification and basic properties

, 2017
STRUMOK is a word-oriented additive stream cipher, where a word in the specification is chosen to be 64 bits. STRUMOK cipher uses some basic design principles from the stream cipher SNOW 2.0.

Some observations of near collision attacks on grain v1

Cybersecurity
Near collision attacks and fast near collision attacks on stream ciphers are controversial attack methods in the field of cryptography in recent years, and their attack results are based on reduced experimental observations and derivation of birthday ...

Revisiting the Security of the Lightweight Stream Cipher Draco: New Observation and TMDTO Attacks

IET Information Security
Draco is a lightweight small-state stream cipher proposed in 2022. It is designed to provide a 128-bit security level and be provably secure against time-memory-data trade-off (TMDTO) attacks. In this paper, we revisit the security of Draco against TMDTO

Sosemanuk, a fast software-oriented stream cipher. eSTREAM, ECRYPT Stream Cipher

, 2005
Sosemanuk is a new synchronous software-oriented stream cipher, corresponding to Profile 1 of the ECRYPT call for stream cipher primitives. Its key length is variable between 128 and 256 bits. It accommodates a 128-bit initial value.

Weak key-IV pairs in the A5/1 stream cipher [PDF]

, 2014
A5/1 is a shift register based stream cipher which provides privacy for the GSM system. In this paper, we analyse the loading of the secret key and IV during the initialisation process of A5/1.

COZMO - A new lightweight stream cipher

, 2018
This paper deals with the merger of the two lightweight stream ciphers – A5/1 and Trivium. The idea is to make the key stream generation more secure and to remove the attacks of the individual algorithms. The bits generated by the Trivium cipher (output)

The stream cipher RC4

, 2006
In the present work we study a class of generalised inner states of the cipher RC4, the so-called persistent states. The RC4 stream cipher is the most widely used software-based stream cipher and the existence of such a state would be a significant ...

a new stream cipher

, 2000
. In this paper a new word-oriented stream cipher, called SNOW, is proposed. The design of the cipher is quite simple, consisting of a linear feedback shift register, feeding a finite state machine.

The Rabbit Stream Cipher

, 2008
. The stream cipher Rabbit was first presented at FSE 2003 [5], and no attacks against it have been published until now. With a measured encryption/decryption speed of 3.7 clock cycles per byte on a Pentium III processor, Rabbit does also provide very ...

Slid pairs in the initialisation of the A5/1 stream cipher [PDF]

, 2013
A5/1 is a shift register based stream cipher which uses a majority clocking rule to update its registers. It is designed to provide privacy for the GSM system. In this paper, we analyse the initialisation process of A5/1.
