Differential Fault Attack on the PRINCE Block Cipher.
Ling Song, Lei Hu · 2013
Abstract. PRINCE is a new lightweight block cipher proposed at the ASIACRYPT’2012 conference. In this paper two observations on the linear layer of the cipher are presented. Based on the observations a differential fault attack is applied to the cipher under a random nibblelevel fault model. The attack uniquely determines the 128-bit key of the cipher using less than 7 fault injections averagely. In the case with 4 fault injections, the attack limits the key to a space of size less than 2 18 statistically. Key words: lightweight cipher, PRINCE block cipher, differential fault attack 1
