Title:
Two Kinds of Biclique Attacks on Lightweight Block Cipher PRINCE

Authors: Zheng Yuan, Zhen Peng, Haiwen Ou

Abstract:

Inspired by the paper [10], using better differential characteristics in the biclique construction, we give another balanced biclique attack on full rounds PRINCE with the lower complexity in this paper. Our balanced biclique attack has 2^62.67 computational complexity and 2^32 data complexity. Furthermore, we first illustrate a star-based biclique attack on full rounds PRINCE cipher in this paper. Our star-based biclique attack has computational complexity 2^63.02 and the required data can be reduced to only a single plaintext-ciphertext pair, this is the optimal data complexity among the existing results of full round attack on PRINCE.
