基于入侵弹性的密码进化方案构造了一个入侵弹性的电子货币系统。在该系统中,银行公钥保持不变,在每个时间段内可多次随机的刷新密钥,使密钥泄漏带来的危害达到最小,且为货币赋予生命周期,从而降低重复花费检测与存储的代价。
Based on intrusion-resilient key evolution scheme,a new e-cash system is put forward. The bank public key keeps unchanged, while the private key of the issuer is evolved randomly over every period. This method makes the harm of private-key leakage touch bottom. Each coin is endowed with a life circle ,which reduces the cost of double-spending check and storage.
