The Grain 128a stream cipher was first purposed at Symmetric Key Encryption Workshop (SKEW) in 2011 as an improvement of the predecessor Grain 128, which added security enhancements and optional message authentication using the Encrypt & MAC approach. One of the important features of the Grain family is that the throughput can be increased at the expense of additional hardware. Grain 128a is designed by Martin Ågren, Martin Hell, Thomas Johansson and Willi Meier. (Wikipedia).

Recovery, Recyrstallization, and Grain Growth
As metals are deformed and then heated they undergo recovery, recrystallization, and grain growth. The hardness, yield strength, ductility, and grain size all change wildly during these processes. Old, deformed grains are replaced by defect-free grains which grow over time via Ostwald ripe
