Detailed Description

Parameter structure for function mcuxClEcc_Verify.

Field Documentation

curveParam

mcuxClEcc_DomainParam_t mcuxClEcc_Verify_Param_t::curveParam

[in] structure of InputBuffers for curve parameters and length of parameters.

pPrecG

mcuxCl_InputBuffer_t mcuxClEcc_Verify_Param_t::pPrecG

[in] InputBuffer for octet string of pre-computed point of base point G, which is of the same format as base point G.

It is calculated as (2 ^ (byteLenN * 4)) * G.

pHash

mcuxCl_InputBuffer_t mcuxClEcc_Verify_Param_t::pHash

[in] InputBuffer for string of message digest (hash), of which the length is byteLenHash (in optLen).

pSignature

mcuxCl_InputBuffer_t mcuxClEcc_Verify_Param_t::pSignature

[in] InputBuffer for to octet string of signature R and S.

Each of R and S is a Big-endian octet string of the exact length curveParam.byteLenN. The string of R is followed by the string of S.

pPublicKey

const uint8_t* mcuxClEcc_Verify_Param_t::pPublicKey

[in] pointer to octet string of public key, which is of the same format as base point G.

pOutputR

mcuxCl_Buffer_t mcuxClEcc_Verify_Param_t::pOutputR

[out] Buffer for memory area in which signature R calculated by verify function will be exported if signature is valid.

It will be stored as a Big-endian octet string of the exact length curveParam.byteLenN.

optLen

uint32_t mcuxClEcc_Verify_Param_t::optLen

[in] packed options (reserved) and lengths: bits 0~7: byteLenHash: length of the string of message digest; bits 8~31: reserved.
