Fault Injection Attack on A5/3
Kitae Jeong, Yuseop Lee, Jaechul Sung, Seokhie Hong · 2011
In this paper, we propose a fault injection attack on A5/3 used in GSM. This attack is based on the fault assumption in. That is, it is assumed that we can decrease the number of rounds in block cipher KASUMI of A5/3 by injecting some faults. With small number of fault injections, we can recover the session key of A5/3 supporting a 64-bit session key. This is the first known cryptanalytic result on A5/3 so far.
