A new idea in response to fast correlation attacks on small-state stream ciphers [PDF]
, 2020 In the conference “Fast Software Encryption 2015”, a new line of research was proposed by introducing the first small-state stream cipher (SSC). The goal was to design lightweight stream ciphers for hardware application by going beyond the rule that the ...

On designing secure small-state stream ciphers against time-memory-data tradeoff attacks [PDF]
, 2019 A new generation of stream ciphers, small-state stream ciphers (SSCs), was born in 2015 with the introduction of the Sprout cipher. The new generation is based on using key bits not only in the initialization but also continuously in the keystream ...

Transformation and Security Analysis of NLFSR-based Stream Ciphers [PDF]
, 2020 © 2020 Ge YaoThe Nonlinear Feedback Shift Register (NLFSR) based stream cipher is becoming the mainstream design of modern stream ciphers. The properties of high operation speed, small footprint in hardware and low power consumption make such ciphers ...

Necessary conditions for designing secure stream ciphers with the minimal internal states [PDF]
, 2017 After the introduction of some stream ciphers with the minimal internal state, the design idea of these ciphers (i.e. the design of stream ciphers by using a secret key, not only in the initialization but also permanently in the keystream generation) has

A related-key chosen-iv distinguishing attack on full Sprout stream cipher [PDF]
, 2015 Sprout is a new lightweight stream cipher proposed at FSE 2015. According to its designers, Sprout can resist time-memory-data trade-off (TMDTO) attacks with small internal state size.

Generic related-key and induced chosen IV attacks using the method of key differentiation [PDF]
, 2013 Related-key and chosen IV attacks are well known cryptanalytic tools in cryptanalysis of stream ciphers. Though the related-key model is considered to be much more unrealistic scenario than the chosen IV model we show that under certain circumstances ...

Key recovery from state information of sprout: Application to cryptanalysis and fault attack [PDF]
, 2015 Design of secure light-weight stream ciphers is an important area in cryptographic hardware & embedded systems and a very recent design by Armknecht and Mikhalev (FSE 2015) has received serious attention that uses shorter internal state and still ...

Certain Observations on ACORN v3 and the Implications to TMDTO Attacks
Lecture Notes in Computer Science, 2017 ACORN is a lightweight authenticated cipher which is one of the selected designs among the fifteen third round candidates. This is based on the underlying model of a stream cipher with 6 LFSRs of different lengths and three additional bits. In this paper we consider the scenario that certain amount of key stream bits and some portion of the state is ...

On Lightweight Stream Ciphers with Shorter Internal States [PDF]
Lecture Notes in Computer Science, 2015 . To be resistant against certain time-memory-data-tradeoff (TMDTO) attacks, a common rule of thumb says that the internal state size of a stream cipher should be at least twice the security parameter.
