sigverify_otp_key_states Struct Reference

SRAM representation of the OTP ROT_CREATOR_AUTH_STATE partition. More...

#include <sw/device/silicon_creator/rom/sigverify_otp_keys.h>

Data Fields
uint32_t	ecdsa [kSigVerifyOtpKeysEcdsaCount]
	State of the ECDSA P-256 keys.
uint32_t	spx [kSigVerifyOtpKeysSpxCount]
	State of the SPX keys.

Detailed Description

SRAM representation of the OTP ROT_CREATOR_AUTH_STATE partition.

The data is loaded into SRAM via sigverify_otp_keys_init() and its integrity is verified by sigverify_otp_keys_check() before use.

Static assertions are used inside the implementation to ensure that the size of the data structure matches the size of the OTP partition.
