An Efficient CL-Signature scheme over NTRU Lattices
Sunil Prajapat, Pankaj Kumar, Vishnu Sharma · 2022
The advantages of key escrow and certificate management features over a public key, and identity-based infrastructure has led to extensive use of the CL-Signature in ebusiness, e-government, and programming security to address these underlying issues. Numerous CL-Signature techniques have been proposed based on the elliptic curve, RSA, and chaos. However, the majority of them are vulnerable to attacks using quantum computing. But in quantum time, the lattice-based CL-Signature technique is safe. Therefore, the CL-Signature Scheme, suggested in this study and shown to be secure in post-quantum environments, is implemented on the NTRU lattice. Additionally, the novel approach is more efficient than earlier lattice-based CL-Signature schemes.
