Subjects: Message authentication codes, Data integrity, Storage, Error-correcting codes
Abstract: We have developed a corruption‐correctable message authentication code (CCMAC) that enables data integrity to be verified and corruptions of data to be corrected up to a certain threshold. As in a previous technique for identifying corrupted points, called corruption detectable MAC (CDMAC), the proposed scheme utilizes a system model composed of two types of storage: general and secure. General storage is vulnerable, that is, data stored in it could be attacked by a malicious third party, whereas secure storage is not vulnerable. In this study, we present two methods of the proposed scheme, each of which has a trade‐off relationship regarding the data size requirements between general and secure storage. We also define security notions for our methods and prove that they can be reduced to those of the MAC or CDMAC used as an internal component. [ABSTRACT FROM AUTHOR]
