Detailed Description

This file includes common definitions for PSA storage.

Definition in file storage_common.h.

Macro Definition Documentation

◆ PSA_STORAGE_FLAG_NONE

#define PSA_STORAGE_FLAG_NONE 0

No flags to pass.

Definition at line 36 of file storage_common.h.

◆ PSA_STORAGE_FLAG_WRITE_ONCE

#define PSA_STORAGE_FLAG_WRITE_ONCE (1 << 0)

The data associated with the uid will not be able to be modified or deleted.

Intended to be used to set bits in psa_storage_create_flags_t

Definition at line 37 of file storage_common.h.

◆ PSA_STORAGE_FLAG_NO_CONFIDENTIALITY

#define PSA_STORAGE_FLAG_NO_CONFIDENTIALITY (1 << 1)

The data associated with the uid is public and therefore does not require confidentiality.

It therefore only needs to be integrity protected

Definition at line 38 of file storage_common.h.

◆ PSA_STORAGE_FLAG_NO_REPLAY_PROTECTION

#define PSA_STORAGE_FLAG_NO_REPLAY_PROTECTION (1 << 2)

The data associated with the uid does not require replay protection.

This may permit faster storage - but it permits an attecker with physical access to revert to an earlier version of the data.

Definition at line 39 of file storage_common.h.

◆ PSA_STORAGE_SUPPORT_SET_EXTENDED

#define PSA_STORAGE_SUPPORT_SET_EXTENDED (1 << 0)

Flag indicating that psa_ps_create and psa_ps_set_extended are supported.

Definition at line 55 of file storage_common.h.

◆ PSA_ERROR_DATA_CORRUPT

#define PSA_ERROR_DATA_CORRUPT ((psa_status_t)-152)

PSA storage specific error codes.

Definition at line 58 of file storage_common.h.

Typedef Documentation

◆ psa_storage_create_flags_t

typedef uint32_t psa_storage_create_flags_t

Flags used when creating a data entry.

Definition at line 34 of file storage_common.h.

◆ psa_storage_uid_t

typedef uint64_t psa_storage_uid_t

A type for UIDs used for identifying data.

Definition at line 43 of file storage_common.h.
