An Unconditionally Secure Electronic Cash Scheme with Computational Untraceability
Summary :
We have introduced the first electronic cash scheme with unconditional security. That is, even malicious users with unlimited computational ability cannot forge a coin and cannot change user's identity secretly embedded in each coin. While, the spender's anonymity is preserved by our new blind signature scheme based on unconditionally secure signature proposed in [7]. But the anonymity is preserved only computationally under the assumption that Decisional Diffie-Hellman Problem is intractable.
