Serpent is a 128-bit block cipher planned by Ross Anderson, Eli Biham, and Lars Knudsen as a claimant for the Advanced Encryption Standard. It was a finalist in the AES struggle. The winner, Rijndael, received 86 votes at the preceding AES symposium, while Serpent got 59 votes, Twofish 31 votes, RC6 23 votes, and MARS 13 votes. So, NIST’s alternative of Rijndael as the AES was not astonishing, and they had to be satisfied with silvery in the ‘encryption olympics’. Serpent and Rijndael are fairly comparable; the main dissimilarity is that Rijndael is quicker (having a smaller number of rounds), but Serpent is additional protected (Nazlee, Hussin, & Ali, 2009).

Table II summarizes the comparison of selected neutronics parameters and parallel computation data of the two Monte Carlo code simulations. MCNP and Serpent simulated 200 and 1000 k-code cycles (batches), respectively, including 50 inactive k-code cycles; each k-code cycle consisted of 2 million neutron histories. There is excellent agreement between the two code results; however, Serpent ran much faster than MCNP. In addition, Serpent has the capability to simultaneously use both MPI and OpenMP parallel computing platforms, which reduces the simulation RAM memory requirement.
