Modes of Operation of Stream Ciphers [PDF]

, 2001
A general stream cipher with memory in which each cipher-text symbol depends on both the current and previous plaintext symbols, as well as each plaintext symbol depends on both the current and previous ciphertext symbols, is pointed out. It is shown how to convert any keystream generator into a stream cipher with memory and their security is discussed.

New Practical Attacks on GEA-1 Based on a New-Found Weakness

IET Information Security
GEA-1, a proprietary stream cipher, was initially designed and used to protect against eavesdropping general packet radio service (GPRS) between the phone and the base station.

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

Analysis of lightweight stream ciphers

, 2008
Stream ciphers are fast cryptographic primitives to provide confidentiality of electronically transmitted data. They can be very suitable in environments with restricted resources, such as mobile devices or embedded systems. Practical examples are cell phones, RFID transponders, smart cards or devices in sensor networks. Besides efficiency, security is

A Stream Cipher Based on Chaotic Permutations

پژوهش‌های ریاضی, 2015
In this paper we introduce a word-based stream cipher consisting of a chaotic part operating as a chaotic permutation and a linear part, both of which designed on a finite field.

On properties of GGHN stream cipher

Безопасность информационных технологий, 2016
In this paper we discuss properties of а state transition function of the GGHN cryptosystem, which was proposed in 2005 in CISC as a modification of RC4. For describing the state transition function of GGNH we use automatic language.
