A Time Optimized Secure Method for Digital Signatures

چکیده مقاله

Cloud computing is now an important part of IT enterprise. In recent years, organizations such as banks, hospitals, medical centers etc. have started to rely on cloud services. But there are challenges in the use of cloud computing, such as ensuring the reliability, data integrity and so on. Ensuring data integrity and security, while setup cost is optimal, is one of the most important challenges. In this paper, we propose a fast and secure method to create and evaluate digital signatures. Our method (E-ECDSA) is based on Elliptic Curve Digital Signature Algorithm and is a complement to it. In particular, we consider methods for reducing the burden of generating a constant amount of metadata at the client side. Whereas many prior studies on ensuring remote data integrity did not consider the burden of generating verification metadata at the client side, the objective of this study is to resolve this issue.
