【NUCLEO H533RE】HASH384测试 [复制链接]

• 前言

前一篇我们体验了AES算法，这一篇继续安全相关加速器的HASH-384. 还是按照硬件和软件对比的方式来体验。

• HASH-384

HASH-384原理见https://eips.ethereum.org/assets/eip-2680/sha256-384-512.pdf

 

三.软件算法

参考https://github.com/th-blitz/Hash-Algorithms/blob/main/sha384.c

 

 

• STM32硬件驱动

添加驱动文件

stm32h5xx_hal_hash.c

stm32h5xx_hal_conf.h中取消注释

/*#define HAL_HASH_MODULE_ENABLED */

 

 

初始化

HASH_HandleTypeDef  hhash;

    __HAL_RCC_HASH_CLK_ENABLE();

  hhash.Instance = HASH;

  hhash.Init.DataType = HASH_BYTE_SWAP;

  hhash.Init.Algorithm = HASH_ALGOSELECTION_SHA384;

  if (HAL_HASH_Init(&hhash) != HAL_OK)

  {

    /* 错误 */

  }

 

取消初始化

    __HAL_RCC_HASH_FORCE_RESET();

__HAL_RCC_HASH_RELEASE_RESET();

__HAL_RCC_HASH_CLK_DISABLE();

 

 

计算

  if (HAL_HASH_Start(&hhash, (uint8_t *)Input, INPUT_TAB_SIZE, aDigest, 0xFF) != HAL_OK)

  {

    /* 错误 */

  }

 

 

• 测试

 

shell_func.c中申明实现函数

static void sw_hash384_func(uint8_t* param);

static void hw_hash384_func(uint8_t* param);

 

新增两行命令用于计算

 

  { (uint8_t*)"sw_hash384",   sw_hash384_func,  (uint8_t*)"sw_hash384 input testtimes"},

  { (uint8_t*)"hw_hash384",   hw_hash384_func,  (uint8_t*)"sw_hash384 input testtimes"},

 

实现如下

 

HASH_HandleTypeDef hhash;

int hw_hash384(uint8_t* input, uint8_t* output, uint32_t len)

{

  __HAL_RCC_HASH_CLK_ENABLE();

  hhash.Instance = HASH;

  hhash.Init.DataType = HASH_BYTE_SWAP;

  hhash.Init.Algorithm = HASH_ALGOSELECTION_SHA384;

  if (HAL_HASH_Init(&hhash) != HAL_OK)

  {

return -1;

  }

 

  if (HAL_HASH_Start(&hhash, input, len, output, 0xFF) != HAL_OK)

  {

__HAL_RCC_HASH_FORCE_RESET();

  __HAL_RCC_HASH_RELEASE_RESET();

__HAL_RCC_HASH_CLK_DISABLE();

return -1;

  }

 

   __HAL_RCC_HASH_FORCE_RESET();

__HAL_RCC_HASH_RELEASE_RESET();

__HAL_RCC_HASH_CLK_DISABLE();

return 0;

}

 

int sw_hash384(uint8_t* input, uint8_t* output, uint32_t len)

{

sha384_core(input, len, (uint64_t*)output);

return 0;

}

 

 

static void sw_hash384_func(uint8_t* param)

{

uint32_t inlen;

uint32_t test_times;

if(sscanf((const char*)param,"%*s %s %d",(char*)(&(s_input[0])),&test_times) == 2)

  {

inlen = str2hex_buf(s_input,strlen((char*)s_input));

 

ULONG sw_start_time = tx_time_get();

for(uint32_t i=0; i<test_times;i++)

    {

sw_hash384(s_input,s_output,inlen);

}

ULONG sw_used_time = tx_time_get()-sw_start_time;

 

xprintf("sw %d\r\n",sw_used_time);

uint8_t* p = (uint8_t*)s_output;

for(int i=0; i<48; i++)

    {

xprintf("%02x",p);

}

xprintf("\r\n");

}

}

 

 

static void hw_hash384_func(uint8_t* param)

{

uint32_t inlen;

uint32_t test_times;

if(sscanf((const char*)param,"%*s %s %d",(char*)(&(s_input[0])),&test_times) == 2)

  {

inlen = str2hex_buf(s_input,strlen((char*)s_input));

 

ULONG hw_start_time = tx_time_get();

for(uint32_t i=0; i<test_times;i++)

    {

hw_hash384(s_input,s_output,inlen);

}

ULONG hw_used_time = tx_time_get()-hw_start_time;

 

xprintf("hw %d\r\n",hw_used_time);

uint8_t* p = (uint8_t*)s_output;

for(int i=0; i<48; i++)

    {

xprintf("%02x",p);

}

xprintf("\r\n");

}

}

 

 

测试如下

 

hw_hash384  01020304050607080900 10000

sw_hash384  01020304050607080900 10000

 

定义了大数组，栈要大点

uint64_t buffer[80];

 

 

硬件计算和在线计算工具计算出来的完全一样

• 总结

以上测试了HASH加速计算，使用硬件加速计算运算很快，接口也很简单。
