Using an efficient hash chain and delaying function to improve an e-lottery scheme

Abstract

A multi-level hash chain structure is employed to improve a fair e-lottery scheme which ensures secure winning number generation and verification and to make verification more efficient. In addition, an implementation of a delaying function based on a secure hash function is presented.

Keywords:
