电子支付系统的各种安全需求依赖于系统的特征和定义在其操作上的信用假设。一般来说,电子支付系统必须具备授权、完整性、保密性、可用性和可靠性。完整性一个具有完整性的支付系统不允许一个用户在没有另一个用户明确授权的情况下取走资金。为了防止行贿受贿,没有允许,系统也不能接收款项。授权构成支付系统中最重要的环节。支付授权有三种方式:外部授权、口令授权和数字签名。

There are three ways to pay for an authorization: external authorization, password authorization, and digital signature.
