一个新的多银行的电子货币系统

A New E-Cash System with Multi-Bank

文章把分布式密钥生成与部分盲签名相结合,构造了一个新的、高效的多银行电子货币系统。该系统中有多个发币行,但并没有增加消息的长度与存储容量;同时,由于使用了部分盲签名,降低了银行密钥管理的复杂性,减少了对存储数据量的需求,提高了银行在存款时的处理效率。

In this paper, we propose a new E-cash system with multi-bank. In this system, there exist many banks, and the coin is as long as it is in [5];on the other hand ,it makes use of partially blind signature, which mitigates the complex of key management for bank, reduces the needs of storage and promote the depositing efficiency.
