TMS320F28035: 可以在035添加mbedtls库是否可行

感谢您对TI产品的关注！
关于你的咨询，我们正在确认你的问题，稍后回复您。

在035工程上添加mbedtls 2.16.0后调用

void aes_cbc_encrypt(const unsigned char *plaintext, size_t plaintext_len,
                     unsigned char *ciphertext, size_t *ciphertext_len,
                     const unsigned char key[16]) {
    unsigned char iv[IV_SIZE] = {0};

    mbedtls_aes_context aes;
    mbedtls_aes_init(&aes);

    // 1. 设置加密密钥
    mbedtls_aes_setkey_enc(&aes, key, 128);

    // 2. PKCS7填充
    size_t padded_len = ((plaintext_len + 15) / 16) * 16;
    unsigned char padded[padded_len];
    memcpy(padded, plaintext, plaintext_len);
    memset(padded + plaintext_len, padded_len - plaintext_len, padded_len - plaintext_len);

    // 3. 加密
    mbedtls_aes_crypt_cbc(&aes, MBEDTLS_AES_ENCRYPT, padded_len,
                         iv, padded, ciphertext);
    *ciphertext_len = padded_len;

    mbedtls_aes_free(&aes);
}

unsigned char MiYao[] = {0xE1, 0xFF, 0xCA, 0xF2, 0x5F, 0xA4, 0x2A, 0x92, 0x47, 0x02, 0x9C, 0xAD, 0x10, 0x34,0x30}; // 秘钥
unsigned char A[] = {0x02}; // 带加密数据

unsigned char *ciphertext = NULL;
size_t ciphertext_len = 0;

void Aes_Test(void)
{
    aes_cbc_encrypt(A,(size_t)1,ciphertext,&ciphertext_len,MiYao);
}


//在主循环中调用一次Aes_Test主循环寻中调佣

 void vMain_Loop(void)
 {
    //局部变量定义
     static Uint16 u16S12V_count =0;//12V急停开关量计数
     static Uint16 u16TempTest = 0;//

     Uint32 u32PFCpowerMIN =0;
     if(u16TempTest == 0)
     {
         u16TempTest = 1;
         Aes_Test();
     }
 }

您好，

      1   c2000系列芯片没有集成MbedTLS的示例。

      2   TMS320F28035不支持，请参考Understanding Security Features for C2000 Real-Time Control MCUs (Rev. E)
