摘要: A new version of the stream cipher Grain-128 is proposed. The version, Grain-128a, strengthened against all known attacks and observations on original Grain-128, has built-in support for authentication. changes are modest, keeping basic structure Grain-128. This gives a high confidence in Grain-128a allows easy updating existing implementations.
