| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The data registered on the blockchain cannot be changed again, but Policy-based Chameleon Hash (PCH)by Derler et al. (2019) enables the blockchain to be modified.This allows users who satisfy the access policy to rewrite the data. However, PCH has a feature that even a user who has lost the access privileges can modify the blockchain using the key he or she has. In this paper, we propose Revocable Policy-based Chameleon Hash (R-PCH).The proposed R-PCH provides additional security to existing PCHs by allowing users who have lost their access privileges to revoke them. | |
