Small-state stream ciphers (SSCs) idea is based on using key bits not only in the initialization but also continuously in the keystream generation phase. A time-memory-data tradeoff (TMDTO) distinguishing attack was successfully applied against all S

In Fast Software Encryption (FSE) 2015, while presenting a new idea (i.e., the design of stream ciphers with the small internal state by using a secret key, not only in the initialization but also in the keystream generation), Sprout was proposed. Sp

We propose a new attack framework based upon cube testers and d-monomial test. The d-monomial test is a general framework for comparing the ANF of the symmetric cipher’s output with ANF of a random Boolean function. In the d-monomial test, the focu

Grain-128a is a well-known stream cipher which has resisted against all types of single-key attacks since its introduction in 2011. A chosen IV conditional differential attack was applied on Grain-128a with 177 initial rounds. It was a distinguishing

A5/1 is a stream cipher used in GSM to provide over-the-air communication privacy. Biham and Dunkelman proposed an attack on A5/1 with time complexity of 2^(39.91) and data complexity of 2^(21.1) known bits and memory complexity of 32 GB. In this pap
