HUKS Changelog

cl.huks.1 Change of the Permission for Using attestKeyItem

The attestKeyItem interface attests a key using a public key encapsulated based on the device certificate chain. Any arbitrary export of the device certificate increases the risks on user privacy. Therefore, certain permissions are required for using this interface.

Change Impact

Applications without the ohos.permission.ACCESS_IDS permission or the system_basic or system_core permission cannot call attestKeyItem().

Key API/Component Changes

  • Involved APIs:

attestKeyItem(keyAlias: string, options: HuksOptions, callback: AsyncCallback<HuksReturnResult>): void; attestKeyItem(keyAlias: string, options: HuksOptions): Promise<HuksReturnResult>;

  • Before change:

The AccessToken permission is verified only for the applications that pass in a tag related to ATTESTATION_ID.

  • After change:

attestKeyItem() can be called only by a system application with the system_basic or system_core permission or an application with the ohos.permission.ACCESS_IDS permission.

Adaptation Guide

Applications with the system_basic or system_core permission can call attestKeyItem(). If an application with the normal permission needs to call attestKeyItem(), it must have the ohos.permission.ACCESS_IDS permission. For details about how to apply for the permission, see ACL.
