A Practical-Time Related-Key Attack on the KASUMI Cryptosystem Used in GSM and 3G Telephony

Orr Dunkelman, Nathan Keller, Adi Shamir
2013 Journal of Cryptology  
The existence of better related-key attacks on the full KASUMI was already shown in [8, 21] .  ...  They will soon be replaced by the new A5/3 (and the soon to be announced A5/4) algorithm based on the block cipher KASUMI, which is a modified version of MISTY.  ...  However, the new attack uses both related keys and chosen messages, and thus it might not be applicable to the specific way in which KASUMI is used as the A5/3 encryption algorithm in third generation  ...

Differential Fault Attack on KASUMI Cipher Used in GSM Telephony

Zongyue Wang, Xiaoyang Dong, Keting Jia, Jingyuan Zhao
2014 Mathematical Problems in Engineering  
As an algorithm in this family survived from cryptanalysis, A5/3 is based on the block cipher KASUMI. This paper describes a novel differential fault attack on KAUSMI with a 64-bit key.  ...  Taking advantage of some mathematical observations on the FL, FO functions, and key schedule, only one 16-bit word fault is required to recover all information of the 64-bit key.  ...  We denote KASUMI with 64-bit key by KASUMI-64 and A5/3 with 64bit session key by A5/3-64, respectively.  ...

Multidimensional Zero-Correlation Linear Cryptanalysis of the Block Cipher KASUMI [article]

Wentan Yi, Shaozhen Chen
2014 arXiv   pre-print
Moreover, zero-correlation linear attacks on the last 7-round KASUMI are also introduced under some weak keys conditions. These weak keys take 2^-14 of the whole key space.  ...  For the attack under weak keys conditions on the last 7 round, the data complexity is about 2^62.1 known plaintexts and the time complexity 2^110.5 encryptions.  ...  In the related-key setting, Blunden et al. [6] gave a related-key differential attack on 6-round KASUMI. Using related-key booming and rectangle attack, Biham et al.  ...

Application of FSM Machine and S-Box in KASUMI Block Cipher to Improve Its Resistance Against Attack

Raja Muthalagu, Subeen Jain
2018 International Journal of Network Security  
Also, few changes are made in a KI and KL keys that are used in a different rounds of KASUMI to prevent various attacks such as a rectangle attack, sandwich attack, single key attack, etc.  ...  The addition of FSM in KASUMI is introducing the non-linearity in output bits and it will increase the complexity for an attacker to make an attack.  ...  In GSM, KA-SUMI is used in the A5/3 key stream generator and in GPRS in the GEA3 key stream generator.  ...

Reducing the time required by KASUMI to generate output by modifying the FL and FI functions

Raja Muthalagu, Subeen Jain
2018 Iran Journal of Computer Science  
In addition, the FI function uses S7 and S9 tables only one time instead of two times in the existing KASUMI block cipher, which leads to reduce the overall time delay.  ...  Also, we proposed a modification in FL functions: FL(a) and FL(b) of the existing KASUMI block cipher.  ...  Some of the modifications were also proposed to optimize the functioning of KASUMI [8] . In 2014, Wang et al. DFA attacked KASUMI-64, which is the base of the A5/3 cryptosystem.  ...
