Functions

func Zuc

func Zuc(k, iv []byte, wlength uint32) []uint32

Types

type Br

type Br struct {
	// contains filtered or unexported fields
}

Br : bit-reorganization, the middle layer of the zuc algorithm.

It extracts 128 bits from the cells of the LFSR and forms 4 of 32-bit words. (x0, x1, x2, x3)

type Fsm

type Fsm struct {
	// contains filtered or unexported fields
}

Fsm : nonlinear function, the bottom layer of the zuc algorithm.

It has 2 of 32-bit memory cells. (r0, r1)

type Lfsr

type Lfsr struct {
	// contains filtered or unexported fields
}

Lfsr : linear feedback shift register, the top layer of the zuc algorithm.

It has 16 of 31-bit cells (s0, s1,…, s15).
