Several versions of the cipher have been proposed within its family, but in this article (and in Gohr’s work [11]) we will focus mainly on SPECK-32/64, the 32-bit block 64-bit key version of SPECK, which is composed of 22 rounds (for simplicity, SPECK-32/64 will be referred to as SPECK in the rest of the article).
WebSpeck key schedules for all variants with 64- and 128-bit blocks later. Given an array of 16 plaintext bytes, pt, and an array of 32 key bytes, k, the array of 16 ... For Feistel ciphers like Simon, it is a common trick to encrypt two rounds at a time so as to avoid swapping words. The same sort of trick can be applied to the various key ... WebJan 1, 2014 · SPECK is a typical ARX cipher and SIMON consists of ANDs, rotations, and XORs. They have various parameters. The algorithms with 128-bit block are comparable with LEA. The Performance of LEA is faster than SIMON in both 32- and 64-bit processors. Since SPECK uses 64-bit addition with 128-bit block, its performance exceeds that of LEA …
Speck is a family of lightweight block ciphers publicly released by the National Security Agency (NSA) in June 2013.
