"Due to the rapidly growing impact of mobile phones, smart cards, RFID tags and sensor networks, lightweight cryptography which is suitable for such resource-constrained devices becomes more and more important. PRIDE is a lightweight block ciphers designed by Albrecht et al., appears in CRYPTO 2014. The designers claim that the construction of linear layers is nicely in line with a bit-sliced implementation of the S-box layer and security. In this paper, the authors find 8 2-round iterative related-key differential characteristics, which can be used to construct 18-round related-key differentials."
