流密码Grain是esteam体系基于硬件的候选的密码算法，最终胜出的三个中的一个-Grain (stream cipher) are one of the estream ciphers based on hard ciphers

grain A new stream cipher, Grain-128, is proposed. The design is very small in hardware and it targets environments with very limited resources in gate count, power consumption, and chip area. Grain-128 supports key size of 128 bits and IV size of 96
