本文档描述了与密钥管理相关的数据元素，该数据元素可以在事务消息中传输，以传递有关用于保护当前事务的加密密钥的信息，也可以在加密服务消息中传输，以传递有关用于保护未来事务的加密密钥的信息。 本文件阐述了ISO 8583-1中与密钥管理相关的数据元素的使用要求，使用了DEA和TDEA的以下两个ISO 8583-1数据元素: -安全相关控制信息（数据元53）； -密钥管理数据（数据元素96）。 与DEA和TDEA密钥管理相关的数据元素由两个ISO 8583-1消息元素串联而成，数据元素53-安全相关控制信息，数据元素96-密钥管理数据。 它传递有关关联交易的加密密钥的信息，并分为子字段，包括控制字段、密钥集标识符和其他可选信息。对于AES实现，数据元素汇总在一个字段中。 本文件适用于对称或非对称密码系统。

This document describes a data element related to key management which can be transmitted either in transaction messages to convey information about cryptographic keys used to secure the current transaction, or in cryptographic service messages to convey information about cryptographic keys to be used to secure future transactions. This document addresses the requirements for the use of the data element related to key management within ISO 8583-1, using the following two ISO 8583-1 data elements for DEA and TDEA: — security related control information (data element 53); — key management data (data element 96). The data element related to key management for DEA and TDEA is constructed from the concatenation of two ISO 8583-1 message elements, data element 53 — security related control information, and data element 96 — key management data. It conveys information about the associated transaction's cryptographic key(s) and is divided into subfields including a control field, a key-set identifier and additional optional information. For AES implementations, the data elements are summarized in one field. This document is applicable to either symmetric or asymmetric cipher systems.
