Related-Key Differential Cryptanalysis of Reduced-Round ITUBee
Xiaoming Tang and Weidong Qiu and Zheng Gong and Zheng Huang and Jie Guo
Abstract
ITU{\scriptsize{BEE}} is a software oriented lightweight block cipher, which is first proposed at LightSec 2013. The cipher is especially suitable for limited resource application, such as sensor nodes in wireless sensor networks. To evaluate the security level of the cipher, we perform differential attacks on ITU{\scriptsize{BEE}} reduced to 10 rounds and 11 rounds with the time complexities ${2^{65.97}}$ and ${2^{79.03}}$, respectively. To our best knowledge, our analysis is the first related-key differential cryptanalysis on the security of 10-round ITU{\scriptsize{BEE}}.
Note: The differential probability is not rightly calculated.
