Abstract
In this paper, a novel digital signature scheme called the RS-signature scheme is proposed, which combines Reed-Solomon (RS) codes and the Elliptic Curve Digital Signature Algorithm (ECDSA). In conventional signature schemes, embedding a digital signature of the original file into the file itself changes its hash value, and this makes it impossible to generate a signature-embedded file in which the file itself is the target of the signature. However, by employing the proposed scheme, it becomes possible to generate such a signature-embedded file. In this paper, the theory and algorithm of the proposed scheme are first presented. Next, to demonstrate its validity, the scheme was applied to image authentication experiments, yielding results that show practical-level authentication speed and reliability. The RS signature scheme can, in principle, be applied to a wide variety of file formats. To demonstrate its extensibility, the scheme was also applied to experiments using HTML files, and satisfactory results were obtained.
