Answer to Question #203589 in Quantum Mechanics for Swera Ijaz

Question

How are wireless smart sensor networks based on quantum tunneling?

Answer 1

With the development of wireless sensor networks, devices are crucial for the Smart City; these devices change people’s lives such as e-payment and e-voting systems. However, in these two systems, the state-of-art authentication protocols based on traditional number theory cannot defeat a quantum computer attack. In order to protect user privacy and guarantee trustworthy of big data, proposed a new identity-based blind signature scheme based on number theorem research unit lattice, this scheme mainly uses a rejection sampling theorem instead of constructing a trapdoor. Meanwhile, this scheme does not depend on complex public key infrastructure and can resist quantum computer attack. Then it's designed an e-payment protocol using the proposed scheme. Furthermore, the scheme is secure in the random oracle, and satisfies confidentiality, integrity, and non-repudiation. Finally, the proposed scheme outperforms the other traditional existing identity-based blind signature schemes in signing speed and verification speed, outperforms the other lattice-based blind signature in signing speed, verification speed, and signing secret key size.
