zuc序列密码算法c语言

根据提供的引用内容，以下是一个使用C语言实现的ZUC序列密码算法的示例：

#include <stdio.h>
#include <stdint.h>

#define ROL32(x, n) (((x) << (n)) | ((x) >> (32 - (n))))

void zuc(uint32_t *k, uint32_t *iv, uint32_t *keyStream) {
    uint32_t R1, R2, F, W, B, u, v;
    int i;

    R1 = k[0];
    R2 = k[1];

    for (i = 0; i < 32; i++) {
        F = (R1 + ROL32(R2, 15)) ^ iv[i];
        W = ROL32(R1, 2) ^ ROL32(R1, 10) ^ ROL32(R1, 18) ^ ROL32(R1, 24);
        B = ROL32(R2, 31) ^ W;
        u = F + B;
        v = F + ROL32(B, 1);

        R1 = ROL32(R1, 31);
        R2 = ROL32(R2, 29);

        keyStream[i] = u;
        keyStream[i + 32] = v;
    }
}

int main() {
    uint32_t k[2] = {0x01234567, 0x89ABCDEF};
    uint32_t iv[32] = {0x01234567, 0x89ABCDEF, 0xFEDCBA98, 0x76543210, 0x01234567, 0x89ABCDEF, 0xFEDCBA98, 0x76543210,
                       0x01234567, 0x89ABCDEF, 0xFEDCBA98, 0x76543210, 0x01234567, 0x89ABCDEF, 0xFEDCBA98, 0x76543210,
                       0x01234567, 0x89ABCDEF, 0xFEDCBA98, 0x76543210, 0x01234567, 0x89ABCDEF, 0xFEDCBA98, 0x76543210,
                       0x01234567, 0x89ABCDEF, 0xFEDCBA98, 0x76543210, 0x01234567, 0x89ABCDEF, 0xFEDCBA98, 0x76543210};
    uint32_t keyStream[64];

    zuc(k, iv, keyStream);

    printf("Key Stream:\n");
    for (int i = 0; i < 64; i++) {
        printf("%08X ", keyStream[i]);
        if ((i + 1) % 8 == 0) {
            printf("\n");
        }
    }

    return 0;
}

这个示例演示了如何使用C语言实现ZUC序列密码算法。在主函数中，我们定义了初始密钥k和初始向量iv，并创建了一个数组来存储生成的密钥流。然后，我们调用zuc函数来生成密钥流。最后，我们打印出生成的密钥流。
