E-Commerce Security by Quantum Digital Signature-Based Group Key Management

Abstract

The Internet development is high over the past decades and there is a lot of cloud computing technology is used in business and other purposes. This leads to the major tread to the security in the cloud and secure communication is much required. Quantum Key Distribution (QKD) is one of the most common methods used to provide better encryption. The main focus of this research is that provide secure communication from the group keying. The Quantum Digital Signature-based Group Key management (QDSGKM) combines QKD with the Fibonacci, Lucas, and Fibonacci–Lucas matrices, which provides the quantum digital signature checks. This method gives the technique to verify the integration of information received by the participants, to authenticate the identity of the participants, and to improve the verification of the signing verification. The experimental result shows that the proposed system provides the security with less delay when compared to the QKD system.
