Lattice-Based Encrypted Verifiably Encryption Signature Scheme for the Fair and Private Electronic Commence
To achieve the fairness and the privacy of the e-commence, and also to consider the quantum security of the e-commence, a lattice-based encrypted verifiably encryption signature scheme (EVES) is proposed in this paper. We achieve the strong unforgeability and the opacity properties in the standard m...

To achieve the fairness and the privacy of the e-commence, and also to consider the quantum security of the e-commence, a lattice-based encrypted verifiably encryption signature scheme (EVES) is proposed in this paper. We achieve the strong unforgeability and the opacity properties in the standard model over lattice without the help of the lattice-based delegation technologies which is one of main tools to achieve the standard model security for the lattice-based cryptography. It is shown that the proposed scheme can be used to design a fair and privacy-preserving e-commence system in cloud, not only for business-to-customer business(B2C) but also for customer-to-customer business(C2C). The main reason is that the verifier can read the details of the EVES by easily computation operations before the EVES is verified.
