A New Approach to Divisible E-cash System

摘要

In this paper a divisible e-cash system for some special applications is proposed using the secret sharing scheme. A verifiable secret sharing scheme based on the intractable discrete logarithm problem is put forward as the building block in constucting the e-cash system. The security of the divisible e-cash system can be derived directly from the security of the well-known Schonrr identification and signature schemes and the security of intractable discrete logarithm problem.
