A Note on Stream Ciphers that Continuously Use the IV
Stream Ciphers Lightweight Cryptography Time-Memory-Data Tradeoff Attacks
font style='font-size:12px;'>
2017/12/6
Time-memory-data tradeoff (TMD-TO) attacks limit the security level of many classical stream ciphers (like E0E0, A5/1, Trivium, Grain) to n/2n/2, where nn denotes the inner state length of the underly...
A new chosen IV statistical distinguishing framework to attack symmetric ciphers, and its application to ACORN-v3 and Grain-128a

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

Armknecht and Mikhalev proposed a new stream cipher ‘Sprout’ based on the design
specification of the stream cipher, Grain-128a. Sprout has shorter state size than Grain family with
a round key func...

Recently, ChaCha20 (the stream cipher ChaCha with 20 rounds) is in the process of
being a standard and thus it attracts serious interest in cryptanalysis. The most significant effort
to analyse Sals...
Dependence in IV-related bytes of RC4 key enhances vulnerabilities in WPA
Key Correlation Plaintext Recovery
font style='font-size:12px;'>
2014/3/11
The first three bytes of the RC4 key in WPA are public as they are derived from the public parameter IV, and this derivation leads to a strong mutual dependence between the first two bytes of the RC4 ...

2014/3/10
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...
Tweakable Enciphering Schemes From Stream Ciphers With IV

We present the first construction of a tweakable enciphering scheme from a stream cipher
supporting an initialization vector. This construction can take advantage of the recent advances in
hardware ...
A Chosen IV Attack Using Phase Shifting Equivalent Keys against DECIM v2

DECIM v2 is a stream cipher submitted to the ECRYPT
stream cipher project (eSTREAM) and ISO/IEC 18033-4. No attack
against DECIM v2 has been proposed yet. In this paper, we propose a
chosen IV atta...
