WebAbstract. In this paper we propose a distinguishing attack on CryptMT, one of the ECRYPT stream cipher candidates, which needs 250 bits of the output se- quence with … WebTrivium and Grain 128 have been studied in [22]. CDC has been applied suc-cessfully in [23] on Grain 128a. In this paper, we show that one can attack Grain v1 up to 106 …

Conditional differential attacks on Grain-128a stream cipher

WebMar 3, 2016 · Moreover, we show new distinguishing attack and key recovery attack on Grain v1 of 107 rounds with lower complexity O(2³⁴) and appreciable theoretical success probability 93.7%. WebTrivium and Grain 128 have been studied in [22]. CDC has been applied suc cessfully in [23] on Grain 128a. In this paper, we show that one can attack Grain v1 up to 106 rounds using CDC method. The paper is organized as follows. In Section 2, we describe the design of Grain v1. We present our experimental results in Section 3. Section 4 gives a funeral for a mother sermon

WebMar 28, 2024 · An attack that reaches the largest number of initialization rounds of Grain-128a in a fixed key scenario thus far is a conditional differential distinguishing attack and reaches 195 initialization rounds, but it works only for a fraction of all keys, . WebOct 25, 2024 · A New Distinguishing Attack on Grain-V1 with 111 Initialization Rounds. 16 November 2024. Zhen Ma, Tian Tian & Wenfeng Qi. ... We then observe this attack on Grain v1, a stream cipher from eStream portfolio whose state size is less than 2.5 times the key size. We will apply similar techniques for mounting an attack on Grain v1 as we … WebGrain v1 is one of the 7 final candidates of ECRYPT eStream project, which involves in the 80-bit secret key. Grain-128 is a variant version with 128-bit secret key, and Grain v0 is the original version in the first evaluation phase. Firstly, we describe a distinguishing attack against the Grain family with weak Key-IVs. funeral for an assassin 1974
