Parallel Implementation of Simeck Family Block Cipher by Using ARM NEON

In these days, it takes a long time, a lot of operations and memory to implement the existing block ciphers based on SPN architecture such as AES, and etc. on the resource-constrained IoT device environment. By this reason, there are a lot of light-weight block ciphers such as SIMON, SPECK, and Simeck support various block/key sizes. In this paper, authors propose efficient implementation methods and results of the Simeck family block cipher on the 32-bit ARM by using ARM NEON SIMD and SIMT. Proposed methods on Simeck32/64 and Simeck64/128 are 8.9 cycles/byte and 12.0 cycles/byte. Proposed methods are 41.4% and 46.9% faster than previous related work respectively.
