生成UDS安全算法DLL文件

使用Visual Studio打开工工程模板，模板在C:UsersPublicDocumentsVectorCANoe10.0 (x64)CANoe Sample ConfigurationsCANDiagnosticsUDSSystemSecurityAccessSourcesKeyGenDll_GenerateKeyEx下，

打开工程GenerateKeyExImpl.vcproj，提示工程转换点确定

修改算法

KEYGENALGO_API VKeyGenResultEx GenerateKeyEx(
const unsigned char* iSeedArray, /* Array for the seed [in] */
unsigned int iSeedArraySize, /* Length of the array for the seed [in] */
const unsigned int iSecurityLevel, /* Security level [in] */
const char* iVariant, /* Name of the active variant [in] */
unsigned char* ioKeyArray, /* Array for the key [in, out] */
unsigned int iKeyArraySize, /* Maximum length of the array for the key [in] */
unsigned int& oSize /* Length of the key [out] */
)
{
unsigned int key = 0U;
unsigned int seed = 0U;
unsigned int i = 0;
if (iSeedArraySize>iKeyArraySize)
return KGRE_BufferToSmall;
// for (unsigned int i=0;i<iSeedArraySize;i++)
// ioKeyArray[i]=~iSeedArray[i];
seed = iSeedArray[1];
seed |= (iSeedArray[0]<<8);

key = seed + 1;

ioKeyArray[1] = key & 0xff;
ioKeyArray[0] = (key>>8)& 0xff;
oSize=iSeedArraySize;

return KGRE_Ok;
}
