This was accomplished by designing Simon ciphers around bitwise AND operations and Speck ciphers around modular addition. [1]

WebCurrently, an interesting research line is the understanding of how powerful machine learning methods are in distinguishing pseudorandom objects from truly random objects. Moving along such a research line, in this paper a deep learning-based pseudorandom distinguisher is developed and trained for two well-known lightweight ciphers, Speck and ...

On Pseudorandomness and Deep Learning: A Case Study
WebSleem and Couturier [24] have suggested Speck-R, ultra-lightweight Speck-based encryption. It is a hybrid cipher that combines addition/rotation/XOR (ARX) with a layer of dynamic substitution. ... Speck is a family of lightweight block ciphers publicly released by the National Security Agency (NSA) in June 2013. Speck has been optimized for performance in software implementations, while its sister algorithm, Simon, has been optimized for hardware implementations. Speck is an add–rotate–xor (ARX) … See more Speck supports a variety of block and key sizes. A block is always two words, but the words may be 16, 24, 32, 48 or 64 bits in size. The corresponding key is 2, 3 or 4 words. The round function consists of two rotations, adding the … See more The following is the designers' reference implementation, written in C, of the Speck variant with a 128-bit block size and key, where key = (K[1], K[0]). It is adapted from their IACR ePrint. Note that this code computes the round keys ( See more Initial attempts to standardise Simon and Speck failed to meet International Organization for Standardization super-majority required by … See more According to ECRYPT's stream cipher benchmarks (eBASC), Speck is one of the fastest ciphers available, both for long as well as short … See more Cryptanalysis The designers claim that Speck, though a "lightweight" cipher, is designed to have the full security possible for each block and key size, against … See more WebApr 30, 2015 · I am trying to implement Speck 64bit block / 128bit key cipher in java.
