WebJan 11, 2024 · SPECK is a family of lightweight block ciphers designed and published by the National Security Agency (NSA) in June 2013. It uses an ARX (Add-Rotate-Xor) structure optimized for performance in software implementations and has been suggested for use on resource constrained devices or the Internet of Things (IoT). WebWhile they are both highly performant in constrained environments, Speck ciphers are optimized towards hardware constrained devices while Simon ciphers favor software constrained environments. This was accomplished by designing Simon ciphers around bitwise AND operations and Speck ciphers around modular addition. [1]
