ippsAESSetupNoise
Turns on the mitigation for AES-ECB mode - the ippsAESDecryptECB and ippsAESEncryptECB processing functions.
Syntax
IppStatus ippsAESSetupNoise(Ipp32u noiseLevel, IppsAESSpec* pCtx);
Include Files
ippcp.h
Parameters
noiseLevel |
The value of this parameter is directly proportional to the amount of noise to be injected. Increasing the noiseLevel by 1 means the delay (performance impact) is doubled. |
pCtx |
Pointer to the IppsAESSpec context. |
Description
ippsAESSetupNoise saves noise parameters in the pCtx context structure. A user-adjustable parameter is noiseLevel, it can be varied from 0 to 4. When the processing function is called with this context it checks the context for noiseLevel value and if it is non-zero, the function enables mitigation mechanism: the data passed to the processing function is divided into chunks, and each chunk is followed by probabilistic noise injection.
Return Values
ippStsNullPtrErr |
Indicates an error condition if pCtx pointer is NULL. |
ippStsContextMatchErr |
Indicates an error condition if the pCtx parameter does not match the operation. |
ippStsLengthErr |
Indicates an error if noiseLevel > 4. |
ippStsNotSupportedModeErr |
Indicates an error condition if the Intel® AES New Instructions (Intel® AES-NI) and Vector AES Instructions (VAES) instructions are not available on the target processor. |
ippStsNoErr |
Indicates no error. |
Any other value indicates an error or a warning.
