+# PRIDE is a modern (2014) lightweight block cipher optimized for 8-bit 
+# microcontrollers, that "significantly outperforms all existing block ciphers
+# of similar key-sizes, with the exception of SIMON and SPECK". Its design 
+# rationale is described in Block Ciphers -- Focus On The Linear Layer (feat. 
+# PRIDE); Martin R. Albrecht, Benedikt Driessen, Elif Bilge Kavun, Gregor 
+# Leander, Christof Paar, Tolga Yalçın: https://eprint.iacr.org/2014/453
