On the Security of the Core of PRINCE Against Biclique and Differential Cryptanalysis

Farzaneh Abed and Eik List and Stefan Lucks

Abstract: PRINCE is a modern involutive lightweight cipher which was proposed by Rechberger et al. in 2012. PRINCE uses 64-bit core cipher, which holds the major encryption logic and is wrapped by two key additions. Thus, the security of the cipher is mainly depending on the security properties of the core. In this paper, we present an independent-biclique attack on the full version and also a differential inside-out cryptanalysis on the round-reduced version of the core of PRINCE.
