ZUC is a stream cipher included in the Long Term Evolution standards used in 3GPP specifications for confidentiality and integrity . It is named after Zu Chongzhi, the fifth-century Chinese mathematician.
It uses a 16-stage linear feedback shift register with each stage in G F ( 2 31 − 1 ) {\displaystyle {\rm {GF}}(2^{31}-1)} and produces a 32-bit word on each tick.
