A systematic approach for encryption and authentication with fault tolerance

摘要

In most studies, data security and fault tolerance are implemented separately. Solutions for each often require considerable software and/or hardware overhead. This paper proposes a systematic approach to integrate authentication and encryption with error detection/correction. Two hash functions in the row direction and in the column direction of a message matrix are introduced to provide intermediate values for the digital signature and serve as checksums for error detection/correction. By sharing the same computation, the total computation overhead is significantly reduced. The proposed approach can detect and correct up to three errors and apply to most cryptosystems.
