摘　　要：ISO8583报文是一个国际标准的包格式,该格式定义了多种字段域,每个字段域有各自的约定格式,并对应特定的功能,字段域分定长和变长两种类型,报文最多可由128个字段域组成,可提供复杂的、扩展性强的、安全性能高的数据协议包。ISO8583协议是金融支付中常用的协议,如POS终端机通过银联与银行金融业务进行业务交互。在实际应用中通常采用位图方式去描述与具体业务相绑定的字段域,由于协议字段域较多且内置的逻辑复杂,增加了应用的难度,而本文则实现了一个能够正向、逆向解析位图的通用功能库,对ISO8583协议相关域进行可视化展现,同时提供了一系列工具函数,对字段域中不同编码格式进行快速转换,实现各种加解密算法及数字签名,为基于ISO8583协议二次开发提供了技术支持。ISO8583 message is an international standard packet format that defines mutiple field fields.Each field has its own format and corresponds to specific functions.There are two types of field:Fixed length and variable length.The message can be composed of 128 fields at most,which can provide complex,scalable and high security data protocol packets.ISO8583 protocol is a commonly used in financial payment.For example,POS terminal machines interact with bank financial business through UnionPay.In practical applications,bitmap is usually used to describe the fields bound to specific services.Due to the large number of fields and complex built-in logic,it increases the difficulty of application.This paper implements a general function library that can parse bitmap forward and backward,visually displays the relevant fields of ISO8583 protocol,and opens a series of tool functions,which can quickly convert different coding formats in the field,realize various encryption and decryption algorithms and digital signatures.It provides technical support for the secondary development based on ISO8583 protocol.
